Pub gardens are an appetising option for many Brits in the sunshine, but some experts have advised people to avoid alcohol in the hot weather in order to keep safe.
The warning has come as alcohol is a diuretic meaning it makes you pee more.
This means that drinking excessively can cause you to become dehydrated, which is especially risky when the temperature soars as high as it's predicted to early next week.
Instead, doctors have advised people to drink lots of water, particularly when out in the sunshine.
Other diuretics include caffeine, with coffee also something to be avoided or cut down when the mercury is rising particularly high.
If you can't resist a beer garden, having a couple of pints or G&Ts in the sun will probably not do you serious harm, but it is a good idea to also drink lots of water and avoid drinking alcohol to excess.
Other measures you can take to minimise risk in the heat are wearing lots of sunscreen which you regularly reapply, as well as wearing sun hats and avoiding being in the direct sun for extended periods.
The NHS website lists the symptoms of heat exhaustion as having a headache, dizziness and confusion, loss of appetite and feeling sick, excessive sweating and pale, clammy skin, cramps in the arms, legs and stomach, fast breathing or pulse, a high temperature of 38C or above, and being very thirsty.
If you've been out in the sun and start to experience these you should get out of the sun and cool off, as well as drinking lots of water.
The Met Office recently issued an extreme weather warning across the UK for the coming days.
Monday is predicted to see the UK hit temperatures in excess of 40C.
Penny Endersby, Met Office chief executive, told the Sun: "The extreme heat that we're forecasting right now is absolutely unprecedented.
"Please treat the warnings we are putting out as seriously as you would a red or amber warning from us for wind or snow and follow the advice.
"Stay out of the sun, keep your home cool, think about adjusting your plans for the warning period."
