I put the shorts on for the first time this year.

And Finn had his cooling mat for the car.

From the BBC^» (British Broadcasting Corporation - home page):

A yellow weather warning has been issued for thunderstorms, which could lead to flooding in parts of England and Wales.

The warning covers areas including Wales, the Midlands, west of England, London and the South East from 12:00 BST to 22:00 on Monday, the Met Office said.

Up to 50mm (1.9in) of rain could fall within a few hours, with a possibility of delays and some cancellations to train and bus services.

England has had its driest start to spring for 69 years, the Environment Agency said earlier this month.

Showers are forecast to drift in from the south in the early hours of Monday, the Met Office said.

Temperatures across the board are due to remain mild in the high teens or early 20s.

The Met Office said there was the "potential for minor localised issues" and flash flooding.

Sunshine and settled conditions will return across the UK^▸ (United Kingdom) for the rest of the week, with temperatures forecast to reach 23C in some parts.

Last week, the Environment Agency warned that water companies that more must be done to safeguard water supplies.

Many places have gone without any rain for weeks, including Preston in Lancashire and parts of Fife which have been dry since mid-April.

According to the UK Centre for Ecology and Hydrology's three month Drought Index, large parts of the UK are in the 'extremely dry' category.

This has implications for the infrastructure of our railways, so I'm posting it here - from the BBC^» (British Broadcasting Corporation - home page):

First heatwave of 2025 likely as temperatures to surge above 30^c

Temperatures are set to soar to more than 30C (86F) this week as an area of high pressure builds across the UK^▸ (United Kingdom).

It will become increasingly hot later this week and by the weekend some places could easily beat the highest temperature recorded so far this year - 29.4C (85F) in Suffolk on 13 June.

For a heatwave to be declared by the Met Office we need to reach a threshold temperature for at least three consecutive days, and that varies from 25C across the north and west of the UK, to 28C in parts of eastern England. Whilst we have seen temperatures exceeding these figures in recent weeks, the warm spells have not been long enough to qualify as a heatwave - but that could be about to change.



The warm weather will be concentrated across East Anglia and south-east England on Monday and Tuesday before spreading across the Midlands, east Wales and north England by the weekend.

On Monday we are likely to reach 26C, by Wednesday the heat becomes much more widespread with highs of 28C, and by the weekend the hot spots surge somewhere between 30 and 33C. Meanwhile, it will become warmer in Northern Ireland and Scotland later in the week, but it will be more comfortable here with temperatures mostly in the low 20s.



By Sunday things become more uncertain and we may see fresher air move in from the Atlantic with a risk of thundery downpours. However, some forecast models keep the heat for longer, especially in East Anglia and south-east England with temperatures continuing to stay above the 30C mark.

Heatwaves are becoming more common due to climate change, with a greater chance of seeing extreme heat.

They can cause problems for our infrastructure, such as trains running at reduced speeds due to the risk of train tracks expanding and buckling in the heat.

We also see more heat-related health problems which can lead to an increase in excess deaths in those with underlying health conditions.

Heat-health alerts are issued to warn health providers of the risk of a heat causing adverse impacts to the health and wellbeing of the population.

The mercury reached the balmy heights of 26 degrees at the end of April and we had cancellations and speed restrictions due to what was described at the time as "severe weather" (much to the memorable hilarity of tourists at Paddington from countries who get genuinely severe weather!) , so it's probably safe to assume similar/worse once it rises a few more degrees.

The mercury may have reached the balmy heights of 26 degrees but track temperatures reached 42 degrees.

Heatwave eases as wind and rain drift across UK^▸ (United Kingdom)

Wind and rain are drifting across the UK, bringing more mild temperatures following a wave of extreme heat, the Met Office said.

It forecast Sunday would feel fresher for most, with sun and scattered showers, and that a weather front was due to push in from the west over Monday evening, bringing a wet end to the weekend.

On Saturday, the UK experienced its hottest day of the year, with temperatures of 33.2C (91.8F) recorded in Charlwood, near Gatwick.

An amber heat health alert covering England, first issued by the UK Health Security Agency (UKHSA) on Thursday, remains in place until 09:00 BST Monday. An amber alert warns health and social care services are likely to be "significantly" affected by the high temperatures, including through an increase in demand and a rise in deaths particularly among those aged 65 or over or with health conditions.

After the hottest weather of the year on Saturday and some late thunderstorms, Sunday has felt very different. Temperatures are lower and the humidity has dropped. Temperatures have reached around 27C in southeast England but more cloud is streaming over the UK on a brisk westerly wind that is bringing showers or longer spells of rain to many areas.

The week ahead will remain more unsettled with some rain at times, together with some sunshine. It will still be cooler and fresher than it has been but there will be some very warm weather at times in eastern parts of England.

Monday will see fewer showers and more sunshine. There could be some light and patchy rain on Tuesday. But later on Wednesday and Wednesday night, muggy air from France means there is the risk of heavy rain and thunderstorms. This should clear on Thursday with more wet and windy weather for northern areas to end the week with warmth further south.

During Saturday's extreme heat, passengers on trains in south London had to evacuate after a fault on a train near Loughborough Junction brought all services in the area to a halt.

"Without power and air conditioning on such a hot day, we pulled all resources from across Sussex and Kent to get personnel on site to safely evacuate passengers as quickly as possible along the track," Thameslink and National Rail said in a statement.

Temperatures above 30C expected as a second June heatwave looms

The second heatwave of 2025 is set to send temperatures soaring back over the 30C mark this weekend.

The hot weather will last into the first part of next week with the heat becoming increasingly intense with the possibility of recording the highest temperature of the year so far.

The hottest day of 2025 to date was recorded on 21 June at Charlwood, Surrey with temperatures reaching 33.2C (91.8F).

Heatwaves are becoming more common due to climate change, with a greater chance of seeing extreme heat.

There are lots of summer events that will be affected by the heat. It's likely to be the hottest start to Wimbledon, surpassing the record of 29.3C (measured at Kew) from 2001. Temperatures will get close to the Glastonbury record of 31.2C (measured at Rodney Stoke) recorded in 2017.



Rain and showers are forecast for Thursday with a fresh feel to the weather.

Humidity increases on Friday as a warm airmass associated with the recent extreme heatwave in the USA makes its way across the Atlantic. Rain and showers will affect the north-west of the UK^▸ (United Kingdom), but with more sunshine in eastern England, temperatures will head into the high 20C's.

It becomes much hotter over the weekend as a ridge of high pressure over Europe influences our weather. On Saturday temperatures will more widely cross 'heatwave thresholds' reaching 27-30C in south-east England, East Anglia, the Midlands and Central Southern England.

By Sunday the heat reaches parts of east Wales and north England. The highest temperatures will be in East Anglia and southeast England reaching 32C in the hotspots.

The heat will get even more intense on Monday, which is likely to be the peak of the heatwave. In East Anglia and south-east England temperatures are likely to reach 33-34C, challenging or surpassing the highest temperature of 2025.

This is extreme heat and isn't far away from the June record which stands at 35.6C (96F), recorded at Southampton during the infamous summer of 1976.

There's more uncertainty in the forecast for Tuesday onwards. Many computer models suggest cooler and fresher air arrives from the west, but it's not inconceivable that the hot weather clings on for another day or so in the east.

No heatwave is expected in Scotland and Northern Ireland with temperatures more generally staying into the low 20Cs. There will be some warm spells of sunshine around, but also the prospect of some areas of rain - for example rain could be heavy on Monday.

Heatwaves can cause problems for our infrastructure, such as trains running at reduced speeds due to the risk of train tracks expanding and buckling in the heat.

We also see more heat-related health problems which can lead to an increase in excess deaths in those with underlying health conditions. Heat-health alerts are issued to warn health providers of the risk of a heat causing adverse impacts to the health and wellbeing of the population.

Health alerts come into force ahead of second heatwave

Heat health alerts have come into force across most of England as the country braces for a second summer heatwave.

An amber alert covers the East Midlands, south-east, south-west, east and London - meaning various health services and the whole population could be affected by the heat, according to the UK^▸ (United Kingdom) Health Security Agency (UKHSA).

In Yorkshire and the Humber, as well as the West Midlands, less serious yellow alerts apply, meaning that the elderly and vulnerable could be affected.

Temperatures are forecast to rise into the 30s over the weekend, coniciding with Glastonbury Festival, before reaching a new high for the year on Monday, when the Wimbledon tennis championship begins.

Monday could be the hottest day of the year so far with a temperature of 34C, possibly 35C in London towards the Cambridgeshire area, according to BBC Weather. The Met Office says London could reach 34-35C.

That would make Monday the hottest ever start to Wimbledon, exceeding the previous opening-day record of 29.3C in 2001 - although players and spectators can expect more comfortable temperatures in the 20s by the middle of next week. The hottest day during Wimbledon as a whole was on 1 July 2015 when 35.7C was recorded.

Temperatures will remain in the mid to high 20s for the 200,000 festival-goers descending on Glastonbury in Somerset this weekend, with a potential peak of 28C on Sunday.

Mark Savage, the BBC's music correspondent at the festival, said shorts, sun hats, bikini tops and bottled water were the order of the day on Friday. He observed no heat-related health issues - other than the occasional red nose and a few very sleepy children.

Although there was little shade at the Pyramid Stage and temperatures were set to soar higher over the weekend, there was plenty of free water and sun cream around the site.

Conditions are expected to remain dry with sunny spells - free of the mud baths of years past - but warm nights could make things for uncomfortable for campers.

Elsewhere in Britain, dry and sunny spells are forecast, with temperatures in the low to mid 20s this weekend. By Monday, Cardiff could match the 30C highs expected across large parts of England.
