A HEATWAVE will see temperatures peak at about 36C later this week – and it comes with a health warning.

Slough will swelter in 30-plus degree heat from tomorrow until Friday, with Thursday set to be the hottest day.

Forecasters are predicting temperatures of 36C, before cooling off towards the weekend.

Slough Observer:

The highest recorded temperature in July is 36.7C, on the first day of the month in 2015 at Heathrow.

And there is a chance that could be topped in some parts in and around London - and possibly in Slough.

Slough Observer:

Ruth May, chief nursing officer for England, said people should take care as temperatures rise, while Asthma UK urged sufferers to keep up their medication.

Dr Andy Whittamore, clinical lead at Asthma UK and a practising GP, said a ‘toxic cocktail’ of hot humid weather and rising pollen levels this week could be ‘extremely hazardous’ for asthma sufferers and could trigger deadly asthma attacks.

He said: "Hot air and hay fever can cause people's airways to narrow, leaving them struggling to breathe, with symptoms like coughing, wheezing, a tight chest and breathlessness.

Slough Observer:

"Hot weather can also increase the amount of pollutants, pollen and mould in the air which can trigger asthma symptoms.

"If you are worried about the weather or hay fever affecting your asthma, make sure you take your hay fever medicines, keep taking your regular preventer as prescribed by your doctor and carry your blue reliever inhaler at all times.”

How hot will it get?

Slough Observer:

Tuesday will see temperatures reach 33C, and after a maximum of 31C on Wednesday, Thursday sees the peak of the heatwave with the BBC predicting 36C.

By the weekend it will feel cooler, with a maximum of 24C in Slough.
