Calderdale will be basking in a heatwave over the weekend and the public are warned to be careful and conserve water.
It will be hot today with plenty of sunshine and temperatures are expected to reach 27 degrees.
Tomorrow, will also bring long periods of sunshine but temperatures slightly lower.
The Met Office said Yorkshire can expect heatwave conditions over the next few days and a level three heatwave alert has been issued.
That means people need to take action to protect themselves from the possible health effects of hot weather.
The Met Office forecasts there is a 90 per cent probability of heatwave conditions through to Sunday evening.
Dr Stephen Morton, Director of the Yorkshire and the Humber Public Health England Centre, said: ““Everyone can enjoy the sun safely by keeping out of the heat at the hottest time of the day, avoiding sunburn and staying hydrated with plenty of cool drinks.
“The elderly and those with long-term illnesses are particularly vulnerable to the effects of very hot weather, so it’s important to look out for them and keep indoor areas as cool as possible.”
The West Yorkshire Ambulance Service has seen a spike in calls over recent days.
Acting Director of Operations David Williams said during periods of high temperatures there is a noticeable increase in ailments brought on by the warmer weather such as breathing difficulties, fainting and unconsciousness.
Mr Williams explained many calls could have been prevented and he said people should be drinking plenty of water, use suncream and stay in the shade early afternoon.
“We know this advice is common sense but, by putting it to the forefront of people’s minds, we hope it will help to reduce the number of people who suffer any ill-effects from the hot weather and cut down the need for ambulance assistance.” he said.
Yorkshire Water is urging customers to be water-wise and only used what they need.
The company, which typically provides its five million customers with around 1.3 billion litres of water a day, has seen demand rise to closer to 1.4 billion litres as temperatures have soared.
Latest figures show that the average British person uses 160 litres a day - 100 litres of water more, per day, than two generations ago.
It’s also significantly more than in countries such as Germany where daily individual consumption levels stand at 127 litres per day.
Matt Thompson of Yorkshire Water said: “We would always urge our customers to be water-wise and only use what they need, regardless of the time of year.
“We’ve seen daily demand for water rise by millions of litres in the last seven days.”
