Soaring temperatures are set to sizzle Manchester this week as the Met Office warned of the third heatwave of the summer.

Temperatures could climb into the low 30s and the heat is forecast to remain at night by the end of next week, with consecutive days of hot weather.

But forecasters said it appears as though the UK will avoid the stifling weather of the high 30s and low 40s seen in the Mediterranean in recent days.

Temperatures in Greater Manchester are expected to reach almost 30C by Friday (July 11) with sunny skies and dry and warm conditions throughout the day. It follows a weekend of cooler air, cloud and rain in most of England.

Marco Petagna, senior meteorologist at the Met Office, said: “I think Wednesday is probably going to be the day when we could start to reach the thresholds of 25 to 28 degrees, depending on where you are.

“But of course, you need three days at those temperatures for it to be able to be called a technical heatwave.

“So, although the temperature will be reaching the criteria, we probably won’t actually reach an official heatwave until around Friday, to give the three consecutive days at those temperatures.

“But temperatures are going to continue to climb as we go toward the end of the week and certainly by Friday and Saturday we could see 30 degrees, perhaps just nudging into the low 30s.

“At the weekend, we could just start to see humidity increasing a little bit as well and night-time temperatures look like they are going to be, so it will be starting to become more uncomfortable by night.”

In Manchester, Monday will see temperatures of around 20C with partially cloudy skies and sunny conditions. Tuesday (July 8) will be much the same, with sun throughout the day and highs of around 20C.

By Wednesday, temperatures will peak at around 24C, rising to 26C by Thursday (July 10). Friday will reach almost 30C in some areas, with average temperatures raising to an average of 29C.

Yet the duration of the hot spell remains difficult to gauge, and there are uncertainties about just how high temperatures will rise.

Mr Petagna added: “It’s a bit of a question mark going through the weekend early next week as to how long the heat will last and how high the temperatures will get, because some models are sort of pushing the heat away a bit more quickly, whereas others keep the heat going.

“At this stage it looks as though certainly into next weekend, we should hold on to hot weather across the south of the UK and temperatures could again certainly get into the low 30s in a few spots.

“And we are going to see some very high pollen and very high UV levels as well.

“But at this stage, we’ve managed to escape some of the very highest temperatures, those seen across Spain and Portugal in particular, where it has reached the mid-40s.”
