Hot weather can affect your health. The people most likely to be affected are the elderly, the very young, and people with pre-existing medical conditions.
The Met Office has also said there will be a high UV count on the three days, with residents urged to make sure they wear sunscreen.
During a heatwave, residents are advised to stay out of the sun; cover up with suitable clothing and sunglasses; take extra care with children; keep your home as cool as possible – shading windows and shutting them during the day may help - and open windows when it is cooler at night.
You should also keep drinking fluids and if there's anybody you know, for example an older person living on their own, who might be at special risk, make sure they know what to do.
