High pressure is building across the UK and this means the weather will become more settled with brighter conditions.

After a chilly start on Monday morning, with sunshine and light winds across much of England and Wales, temperatures will climb into the low 20s.

Even with more cloud in Scotland and Northern Ireland, it will turn warmer with highs also reaching 18 to 22C.

It will also start to feel more humid again.

That more humid air combined with light winds across England and Wales into Tuesday means it will start off rather misty and foggy with areas of low cloud for some.

Once the sun has broken through though, it will feel warmer still.

Temperatures could peak at around 24 or 25C in south-east England, but reach the low 20s Celsius in many other parts of England, Wales, Northern Ireland and Eastern Scotland.

The highest temperature though will be determined by how much the cloud breaks allowing the strong September sunshine through.

2026 has already been a record-breaking year for the number of days above 25C, with last week exceeding the record of 89 days set in 1959.

This river was thought to be the stuff of legends – but it is very real

In a remote part of the Amazonian rainforest, there is a river so mired in myth that many thought it didn’t exist. However, thanks to the research and work of a celebrated geothermal scientist, the existence of the river has now been proven – and he’s fighting to protect it.

The Shanay-timpishka, commonly known as the ‘Boiling River of the Amazon’ is a tributary of the Pachitea River which flows towards the Amazon River. The river has been known to indigenous Peruvians who live in the Amazon, and it has been used for spiritual and healing rituals for centuries. They called it ‘Shanay-timpishka’ which translates to ‘boiled by the heat of the sun’.

The local Asháninka and Shipibo peoples believe the river is birthed by Yacumama, a gigantic mythical serpent thought to live in the Amazon. “a mythical enormous serpent believed to inhabit the Amazon Rainforest.”

Local shamans teach that Yacumama is the “Mother of the Waters”

Geothermal scientist Adrés Ruzo first heard of the scalding river from his grandfather who told him a legend about the Spanish conquistadors who ventured into the jungle and came back with tales of a river which boiled.

He was the first scientist permitted by the local shamans to map, study and legally help to protect the river. He travelled through the jungle in 2011, guided by his aunt and confirmed the existence of the river.

Ruzo worked to study the river, and also helped the local indigenous people secure their rights to it. The area is in massive danger from deforestation which destroys the forest and surrounding ecosystems.

Ruzo became an advocate for the ancestral people living in the region, and helped secure the legal titles to the land. He also founded the Boiling River Project – a non-profit organisation which advocates for the permanent protection of the river.

One of the most fascinating things about this river is that it is an anomaly.

Usually, geothermal rivers and springs are heated by volcanic currents but in the case of Shanay-timpishka, the closest volcano is 700 kilometres away. Instead, the water is heated by the core of the Earth.

Rainwater seeps into the earth’s crust through fault lines where it is heated to boiling and then pushed back up into the river. At its hottest points, the river can reach close to 100°C, and boils anything which is unfortunate enough to fall in.

The river is littered with animal bones and bodies which have been cooked inside.

Tragically, it’s not only animals which have been killed by the boiling water. A Toronto woman died in 2025 after she fell into the river whilst meditating on a rock nearby.

Although Maya Moreno managed to escape from the water alive, she tragically died later in hospital after suffering burns to 70% of her body.

According to a GoFundMe for Maya, she had travelled to the river as part of a spiritual journey, and fainted beside the river which caused her to fall in.
