heat

Three weeks after the autumnal equinox, it finally feels like fall.

Well, kind of.

This past weekend, Southern Californians breathed a collective sigh of relief as an oppressive heat wave broke. Temperatures in L.A. dropped 31 degrees, from 104 degrees on Oct. 4 to one week later, a high of 73 degrees, according to observed weather data.

I felt like a climatological grim reaper when, in the midst of my friends celebrating the drop in temperature, I told them it was temporary, as it was expected to get hot. Again. (I’m great at parties!)

But, even still, I want to help you get outdoors — safely. In this week’s edition of The Wild, our weekly outdoors newsletter, I will share three excellent L.A. hikes that each offer something different — great views or shade, for example — with caveats about the best time to go.

The first caveat is: The National Weather Service issued a red flag watch and warning, which signals an increased risk of fire danger, for much of L.A. and Ventura counties from Thursday morning through Saturday evening. It includes the San Gabriel and Santa Monica mountains. As a result, parks within Santa Monica Mountains National Recreation Area will be closed Thursday through Saturday. The closure applies to land managed by California State Parks, the National Park Service, the Santa Monica Mountains Conservancy and Mountains Recreation and Conservation Authority.

Daniel Swain, UC Agriculture and Natural Resources climate scientist, told my Times colleagues Terry Castleman and Rong-Gong Lin II in a recent story that the greater fire risk will be in communities and natural areas west of the 405 Freeway, as east of the 405 recently saw rain.

“West of that point, almost no rain fell at all, and in early October we had a record-breaking heat wave,” Swain said. “East of the 405 in Southern California, the fire risk is lower because it recently rained.”

Bearing that in mind, two of the hikes below are east of the 405 and the third is an urban hike. All three avoid long drives far into the mountains. The two hikes closest to the foothills have large parking areas and clear exits. The urban hike usually offers clear views that should allow hikers to spot a fire near them and evacuate quickly.

1. A shady hike along a flowing river

Gould Mesa via Gabrielino Trail
Distance: About 4 miles out and back
Elevation gained: About 300 feet
Difficulty: Easier end of moderate
Dogs allowed: Yes
Nearest to: Pasadena, La Cañada Flintridge and Altadena
Accessible alternative: The first mile of this trail is paved. See notes below.

The Gabrielino National Recreation Trail is a 28.8-mile journey from Chantry Flat Recreation Area north of Sierra Madre all the way to the Ventura Street & Windsor Avenue trailhead near the Hahamongna Watershed Park in La Cañada Flintridge. It is a multi-use trail for hikers, mountain bikers and horse riders.

The trail has several beautiful sections, including from its western entrance in Hahamongna to the Gould Mesa Trail Camp. This segment is mostly shaded and great for a morning stroll, especially before 11 a.m. Saturday and Sunday.

To begin your hike, you’ll park at a large free dirt lot near the backside of NASA’s Jet Propulsion Lab. If hiking in a wheelchair or seeking an accessible paved path, I recommend parking at this smaller paved lot, as that’s where the paved portion of the trail begins. (Please leave this lot for folks seeking the accessibility alternative, as it’s smaller than the large dirt lot — and both are free!)

You can either take the paved trail or an unofficial dirt trail that follows the Arroyo Seco before leading you to the official trail. Either way, it’s primarily a mix of flat path and gentle inclines along the Arroyo Seco, shaded by coast live oaks, bay laurels and sycamore trees. After hiking about two miles, you’ll reach the Gould Mesa Trail Camp, where you can set up a picnic at one of the campground’s tables, or cool off along the creek.

And if you’d like to go a bit farther, you can continue onward to the Paul Little Picnic Site or the Brown Mountain Dam waterfall (see map). Regardless of where you stop, I promise you’ll be treated to a stunning landscape and likely hear the chirp and squawk of scrub jays, California quail and more.

2. A canyon hike with incredible views

Dunsmore Canyon & Le Mesnager Loop Trail
Distance: 2.6 miles
Elevation gained: About 800 feet
Difficulty: Moderate
Dogs allowed? Yes
Accessible alternative: Stough Canyon Fire Trail with Action Trackchair AXIS 40

This 2.6-mile hike through the 709-acre Deukmejian Wilderness Park in Glendale will offer you not only great views of the surrounding cities but also an opportunity to spend time among healthy native trees and plants, including California buckwheat, black sage and California sagebrush (which you should smell).

You’ll park in a lot near the Stone Barn Nature Center. Several signs are usually posted around the lot warning visitors about when the park will close, and a staff member will lock the gate. I think that’s serious, so take note.

You’ll start your hike on Dunsmore Canyon Trail, headed northeast up a straight gravel path covered on both sides with thick ceanothus, yerba santa and more.

Although some hikes, like this path in Dunsmore Canyon in Glendale, may appear exposed during the day, you might find they’re shadier in the morning or evening, depending on their local topography.

Just 0.2 miles in, there’s a massive old coast live oak where kids could easily create an imaginary forest kingdom under its large branches.

As you continue to climb, you might hear Dunsmore Creek, which runs parallel to the trail. Remember to turn around as you gain elevation, as this trail rewards you with substantial views of Glendale and the Crescenta Valley soon after you start. All the while, you have the San Gabriel Mountains right in front of you, including Mt. Lukens, which you can hike to from the same park.

Half a mile in, you have the option to continue on the Dunsmore Canyon Trail or Le Mesnager Trail to make a shorter loop. Le Mesnager Trail includes a lookout point at about 2,750 feet, a great spot for sunset as long as you don’t get locked in! As you meander down the trail, you’ll find a nice shady canopy and continued views of the city below.

Given our weekend temperatures, this trail is best in the morning or evening. I personally prefer the latter, when golden hour paints the mountains a deep gold to red.

If you plan to hike it in the evening, though, keep the park hours in mind. It is open until 8 p.m. until Monday, when its hours shift to closing at 7 p.m., which remains until Daylight Saving Time ends Nov 1. This is relevant if you plan to park in the lot. Otherwise, you can walk out of the park and back to your car. Regardless, have fun!

3. An urban hike near a great picnic area

Culver City Stairs to Baldwin Hills Scenic Overlook
Distance: 1.4 miles
Elevation gained: About 350 feet
Difficulty: Moderate
Dogs allowed? Only on the paved road, not on trails
Accessible alternative: Discovery Park and Bluff Creek Trail

This 1.4-mile out-and-back jaunt up 282 concrete steps, known locally as the Culver City Stairs, takes hikers to the stunning Baldwin Hills Scenic Overlook. From here, you’ll have one of L.A.’s most breathtaking — kind of literally — city views.

To begin, you’ll take the Baldwin Hills Scenic Overlook entrance off Jefferson Boulevard. You’ll follow a dirt path briefly east, follow a switchback to the west and soon find stairs. Head straight up, pausing to breathe and appreciate the views. The stairs vary in height, from about 3 to 20 inches, so it’s good to take your time.

At the top, you’ll have panoramic views that, on a clear day, include the Pacific Ocean. To return, you can either head back down the steps or take the meandering dirt trail down.

Culver City is expected to be cooler on Sunday than Saturday, with an expected high of 85 degrees. Why not make it a morning trek followed by brunch?

Regardless of where you go, I hope you have a safe and meaningful time on our public lands!

The must-read

The 90-acre Turtle Conservancy in Ojai was founded in 2005 as a research center and advocate for turtle habitat. But over the past 10 years, its mission has shifted in response to illegal turtle poaching, prompting the small nonprofit to take in 810 turtles — more than 400 of which they received in the past six months. What should the conservancy do once it has the turtles? That question remains heavily debated (and underfunded), an issue covered in a recent Times story by writer Stuart Miller. “It’s so easy to pluck an animal out of the wild, but when you want to put one back there’s more roadblocks,” said conservancy founder Eric Goode. “Can we find a happy medium? Because the best thing for these turtles is not to keep them in holding areas for too long.”

Happy adventuring,

Would you like to help scientists better understand where native species are thriving in L.A. County? Or how about researchers who are tracking where invasive species are taking up loads of space? The L.A. Nature Quest is a monthlong challenge that runs through Oct. 31. The L.A. Public Library helps host the challenge, which asks participants to download the citizen science app iNaturalist and then document the natural world in their neighborhood. This year, quest organizers are especially hoping people will pay attention to “cold spots,” where there is little to no data on habitat in an L.A. neighborhood.

The Singapore Grand Prix has been declared a heat-hazard race, the second weekend in a row that the designation has been used in Formula 1 and the fourth time this year.

The definition allows teams to fit cooling devices to their cars that pump liquid through a vest worn by the driver to manage temperatures in the cockpit.

A heat hazard is an official status for an event where it is forecast that temperatures will exceed 31C at some point during the race. It was first introduced in 2025.

Singapore is close to the equator and has long been known as one of the most demanding for drivers – in 2024, George Russell and Lewis Hamilton were treated for heat exhaustion after the race.

Temperatures in the city are always in the 31-33C region across the race weekend, with high humidity and a chance of rain every day.

The race is held at night, but temperatures remain in the region of 30C even after dark.

A cooling kit is not mandatory, but any driver who chooses not to use it has to carry 5kg of ballast in their car to ensure he does not have a competitive advantage.

The system uses a cooling tank and pump, usually situated in the car’s nose, that delivers a cooled liquid, such as glycol, through a system of pipes in a fireproof top worn under their overalls.

Some teams and drivers prefer not to use the system because of two key compromises.

It is difficult to keep the liquid cool enough for long enough so that it lasts for an entire grand prix – a problem exacerbated in Singapore because it is the longest race of the year.

And some drivers find the cooling top uncomfortable in the tight confines of the cockpit.

If the liquid cannot be kept cool, it reverts to car temperature, which is considerably higher than ambient. It is not unusual for temperatures in an F1 cockpit to rise above 40C.

Mercedes are one of the teams who have decided against running the system because they preferred to devote the resource that would have been involved in making it robust enough to last a race into car performance.

Governing body the FIA has granted teams an allowance under the cost cap of $50,000 (£38,000) if they can make a system that keeps the liquid cool for an entire grand prix, and a further $75,000 (£57,000) if they could make the top comfortable.

Mercedes deputy team principal Bradley Lord described the allowance as “small”, adding: “We didn’t believe that allowance was sufficient for us to be able to develop a solution that would be robust enough to last for the entire race.”

Singapore follows the Austrian, Italian and last weekend’s Bahrain Grand Prix in Malaysia in being declared a heat-hazard race this year.

It was so hot at Dodger Stadium on Saturday…

How hot was it?

It was so hot a team that averaged nearly 50,000 fans for often meaningless regular-season games beat the Atlanta Braves 5-3 in its first postseason game before thousands of empty seats — some of which were literally too hot to sit in.

It was so hot the Dodgers set up pallets of bottled water near the gates and anyone brave enough to enter the stadium was given a plastic 16-ounce Dasini bottle. Gatorade also set up a cooling tent under the right-field pavilion.

It was so hot Nicolas Gonzalez, a fan sitting in the shade of the reserved level, saw a stadium attendant, overcome by heat, stretchered before the game even started. She wasn’t the only one. By the later innings, other fans on the reserved level were reportedly seeking medical attention on the concourse.

The Dodgers declined comment.

So how hot was it?

The game started 45 minutes after the National Weather Service issued an extreme heat warning, cautioning against “extremely dangerous heat conditions” as the temperature reached 100 degrees at first pitch. By the third inning, the temperature reading atop the left-field scoreboard peaked at 103 degrees, matching the highest first-pitch temperature at 64-year-old Dodger Stadium.

“I’ve been coming to games my whole life and this is easily the hottest game I’ve ever been to,” said Gonzalez, 38, of Culver City. “Having a game in these conditions feels like we’re flying too close to the sun, both literally and figuratively.”

Around him, fans tried to cool themselves by waving makeshift fans. It didn’t work.

But the weather didn’t just effect the way the game was watched. It effected the way it was played, too. The cloudless skies made every pop-up an adventure and the warm, dense air reduced drag, allowing batted balls to travel further. As a result, the teams combined for five homers, accounting for all eight runs.

“That’s probably one of the hottest games that we’ve ever had here. And so shout out to the Dodger fans; they were amazing,” said Max Muncy, who hit of those five homers.

“My feet were hot. Really hot.”

The Dodgers wound up with an early afternoon game in the middle of a historic heat wave because MLB and the TV networks — in this case Fox and TBS — set conditional start times for the four Division Series games before the teams and matchups were known. When the San Diego Padres eliminated the Chicago Cubs in the wild-card round, Saturday’s early NL game went to the Dodgers.

Left-hander Tarik Skubal, who gave up just a run on two hits in six innings to get the win in his Dodger postseason debut, said he didn’t really notice the heat until he came out of the game.

“I walked back into the dugout, and I asked — I forget who, I think it was [Blake] Snell — I was like, ‘has it been this hot all game?’ It’s amazing what your brain can do in certain circumstances and moments,” he said.

“I actually didn’t think it was horrible when I was pitching.”

But then Skubal pitched in much hotter conditions as a kid growing up in northern Arizona.

“I played a Little League game in 127 [degrees]. Lake Havasu,” he said. “[Saturday’s] up there with as hot a baseball game that you can play in.

“Every team’s playing in it, right? They’re playing in the same conditions we are. It shouldn’t really impact how you are mentally or how it’s going to impact how you pitch. Just go out there and play baseball and try to drink water. That’s really it.”

At least Skubal got to drink his water in the relative cool of the dugout between innings. Umpire Roberto Ortiz, wearing 10 pounds of protective gear and a black-and-gray uniform, got no such relief. He had to stand behind the plate for 2 hours 44 minutes and all 290 pitches, one of which smoked him in the seventh inning.

That’s why his five fellow umpires made a point of patting him on the back or shoulder before jogging to their positions for the first pitch.

“He stayed tough,” Dodger catcher Will Smith said of Ortiz. “I’m sure he’ll rehydrate and be ready for tomorrow.”

Speaking of tomorrow, the Dodgers, Braves and the umpires will all get some relief for Game 2. At first pitch Sunday afternoon the Weather Channel is forecasting a temperature of just 97 degrees.

“The dark silver lining,” Gonzalez, the heat-weary fan said in a nod to global warming, “is this might be the coolest October of the rest of our lives.”
