Heat exhaustion happens when your body becomes too hot and struggles to regulate its temperature.

An obvious sign is excessive sweating, as well as feeling very hot and unwell - which is your body's way of warning you to cool down, fast.

Other symptoms include headache, dizziness and cramps, but it is not usually serious as long as you can cool yourself down.

Heat exhaustion can turn into heatstroke, which is a medical emergency. It means your body can no longer manage the heat and your core temperature is rising too high. You should get urgent medical help.

The signs to watch for and quickly act on include not sweating even while feeling too hot, a temperature of 40C or above, a seizure and lack of consciousness.

It can be easy to forget just how quickly the UK’s climate is changing.

Days exceeding 30C - known as "very hot" days by the Met Office - might feel normal, but they used to be much rarer.

As a reminder, Heathrow reached 26.9C earlier, making it the warmest day of the year so far. Temperatures are forecast to reach up to 33C in parts of the UK over the bank holiday weekend.

During the last decade, the number of these "very hot" days more than trebled compared with the 1961-1990 average, according to the Met Office.

And these temperatures are especially rare in May.

The Met Office says that 30C has been reached in May in only a handful of years since 1900.

And forecasts suggest that the current May record of 32.8C could be beaten over the upcoming bank holiday weekend.

The UK’s weather varies a lot naturally, but this early season heat is consistent with the long-term trend of rising temperatures because of human-caused climate change.

As a guide dog handler of 27 years, my heart falls every time I hear the fatigued pants of dogs in heatwave weather.

Animal welfare charity the RSPCA says that dogs are 10 times more likely to suffer heat-related illnesses from exercising in hot weather than from overheating in cars. Both are tremendously bad for your dog.

Canines have a very limited ability to regulate their temperature. They don't sweat like humans - only perspiring a small amount through the pads on their paws.

Heavy panting, difficulty breathing, excessive drooling, lethargy and drowsiness are all key signs that your dog is too hot. In extreme cases, dogs vomit and finally lose consciousness.

If your dog is in trouble, the RSPCA says, external you should move the dog to a shaded and cool area and immediately pour cool, but not very cold, water over the dog, avoiding their head.

For these dogs, a walk by the water has been a key part of the day.

Whether it's by the beach, river or canal these pictures from BBC Weather Watchers show the pooches basking in, or finding shade from, the sun.

Keeping cool is essential for dogs in the warm weather. Remember, start with shorter walks and don't push your dog if they are panting heavily.

In our next post, we'll bring you information from the BBC's Sean Dilley on the RSPCA's guidance on keeping dogs safe in the warm weather.

Heathrow has recorded the warmest temperature of the year so far, but not all parts of the UK are experiencing the warm weather.

While a heatwave is expected in parts of the country this weekend, cloudier skies across Scotland and Northern Ireland mean temperatures will only get between 17 to 22C at best.

This will fall well short of the threshold needed to declare an official heatwave - 25C for three days in a row.

But spare a thought for those in the Northern Isles, Scotland, where it’s even cooler. The maximum temperature today and over the weekend is only going to be 11 or 12 degrees.

It's the warmest day of 2026 so far, and temperatures are likely to rise even further throughout today.

In Heathrow, temperatures ticked up to 26.9C, slightly above the previous record of 26.6C in London's Kew Gardens on 8 April.

Here's what you need to know:

Heat warnings

The UK Health Security Agency (UKHSA) has upgraded their heat health warnings covering large parts of England.

Amber warnings have been issued in the East and West Midlands, London, East England and South East England - which means the conditions could impact the whole population in these regions, as well as the NHS and likely travel disruption.

Yellow heat warnings are in force in North East England, North West England, Yorkshire and Humber and South West England. A yellow warning indicates adverse weather likely to affect vulnerable groups.

All warnings are in place until Wednesday 27 May at 17:00 BST.

How can I stay cool?

We've put together a handy guide on how to stay cool in the coming days.

There's also some specific advice on how to tackle hot temperatures depending on your plans: whether it be staying at home, travelling on the train, or catching the football this weekend.

The forecast:

Bank holiday Monday could see the UK's hottest day in May ever, as there is increasing confidence that the maximum temperature could reach 33C.

Over the next five days, the country will be hotter and drier than parts of the Mediterranean and North Africa.

And, here's a fuller forecast of the days to come.

It’s getting very warm out there this lunchtime.

With 26.9C just recorded at Heathrow, it is now the warmest day of the year so far.

We’re expecting temperatures to rise even further so we’ll be able to let you know how hot it eventually gets later this afternoon.

Elsewhere across the UK, temperatures have been rising into the twenties.

But with more cloud around the far west of south-west England, west Wales and northern Scotland, temperatures are much lower at 11-14C. Northern Ireland is also cloudy, but seeing slightly higher temperatures.

It is officially the warmest day of the year so far in the UK, the Met Office has confirmed, as temperatures hit 26.9C in Heathrow.

Previously, the warmest day of 2026 was on 8 April, when heat of 26.6C was recorded in London's Kew Gardens.

Let's step away from the UK for a moment, to understand why we are seeing such high temperatures.

It’s well established that human-caused climate change is making hot weather more likely and more intense.

As humans burn coal, oil and gas and cut down forests, carbon dioxide and other greenhouse gases are released into the atmosphere.

These gases act like a blanket, causing the planet to heat up.

And even a small increase in average temperatures makes a big difference to heat extremes.

As the range of daily temperatures shifts to warmer levels, hotter days become more likely and more intense.

Since the 1980s, the UK has been warming at about 0.25C per decade – and 2025 was the UK’s hottest year ever recorded, the Met Office says.

The London Fire Brigade (LFB) says that risk of wildfire in the English capital is "very real", and is advising people against using disposable barbecues over the bank holiday weekend.

Assistant commissioner Paul McCourt says there will be a heightened risk of wildfires in London over the weekend, according to an assessment from the Met Office's Natural Hazards Partnership.

The LFB says people can prevent wildfires by "not using disposable barbecues", along with "being careful about how they dispose of cigarettes".

The heightened risk is due to the "wetter-than-usual" weather, which has allowed vegetation to grow, followed by "one of the driest Aprils on record", says McCourt.

The UK will be hotter and drier than parts of the Mediterranean and North Africa over the next five days.

Whilst hot, humid air is pushing across north-west Europe, colder air is affecting the south-east of Europe, including Greece and Turkey - popular summer holiday destinations.

It’s a huge weekend coming up for football fans, who are being urged to stay safe in the warm temperatures.

It's the last day of the Premier League on Sunday with games planned across England, and Wembley will be hosting the EFL final play-offs with around 170,000 fans expected across three days.

Supporters of the clubs involved - Hull City, Middlesbrough, Stockport County, Bolton Wanderers, Notts County and Salford City - have been told by Wembley to take extra care.

They've been advised to plan ahead, dress accordingly, and stay hydrated throughout the day, according to a statement seen by the BBC.

Let in cool air: Open windows on opposite sides of the home to encourage air flow. Do this when the air temperature outside is cooler than inside, which tends to be overnight or in the early part of the day.

Keep warm air out: During the peak heat of the day, keep your windows shut and blinds or curtains closed - especially on the side of your home where the sun is shining.

Use a fan: Putting the fan in front of an open window can encourage the fresh air from outside to be blown throughout the room - as long as it is cooler outside.

Limit hot activities: Ovens and cookers emit a lot of heat into the home during and after their use. Sticking to cold foods, such as salads, that don't require cooking can stop unnecessary heat being generated.

Cool yourself down: Tepid showers, wearing natural fibres like linen and cotton and using a cold water bottle on your body can help.

Find an alternative space: If your home is too warm, air-conditioned public buildings such as libraries, leisure centres and shopping centres can provide relief.

Network Rail, which manages many of the railways in Britain, has published some advice for those travelling by train in areas seeing warm weather.

They ask that, in hot weather, travellers:

• Check before travelling and allow more time for journeys
• Carry water bottles, which can be filled up at fountains at big stations
• Avoid boarding trains if feeling unwell, and ask staff for assistance at a help point if needed

Also with a warning is Southern Railway, which says trains are likely to be busier than usual, "particularly on routes to coastal destinations".

As a potential heatwave approaches parts of England, here's a look at how the weather across the UK will be over the bank holiday weekend.

Yellow vs amber

A yellow health alert means that adverse weather is likely to affect vulnerable groups.

An amber alert is issued when weather conditions could affect the whole population or the NHS, with travel disruption likely.

What are the risks?

TheUK's Health Security Agency (UKHSA) is warning that "significant impacts" are likely across health and social care services.

For places subject to yellow warnings:

These include a rise in deaths - particularly among those aged 65 and over or with health conditions - increased demand on health and social care services, and heat affecting the ability of the workforce to deliver services.

For places subject to amber warnings:

The same risks as above stand for places under amber alerts, but the UKHSA gives additional warnings that there could be issues managing medicines, an increased demand for power that exceeds capacity and that other sectors might start to notice issues, such as travel delays.

The amber alerts currently in place have been given a risk of 12, which means there is a 60-89% likelihood of these impacts.

It's worth noting that these heat warnings only cover England, and are not issued for other parts of the UK. Our earlier post covers which places are currently under warnings.

A few moments ago, the UK's Health Security Agency upgraded their heat health alerts in England, and issued new ones to previously unaffected regions.

Regions that have been upgraded from yellow to amber warnings are:

• East Midlands
• West Midlands
• East England
• London
• South East England

Regions upgraded from no alerts to yellow warnings are:

• North East England
• North West England
• Yorkshire and Humber
• South West England

All warnings are in place until Wednesday 27 May at 17:00 BST.

In our next post, we'll bring you more on what these alerts mean.
