Weather Manchester is set for a possible heatwave this week if Greater Manchester reaches 25C on three consecutive days. The Met Office says the area is forecast to hit that level on Thursday and Friday, then climb to 26C on Sunday, putting the region within its heatwave threshold.
Gregory Wolverson, the Met Office deputy chief forecaster, said: "This week’s weather reflects a contrast we often see in summer, with more unsettled conditions passing to the northwest of the UK while heat builds in the south and east." The forecast then shows 22C on Saturday, 28C on Monday and 26C on Tuesday, leaving Monday’s reading as the warmest point in the run.
Greater Manchester threshold
The Met Office says Greater Manchester’s heatwave threshold is 25C, and a heatwave is reached when an area records at least three consecutive days at or above that level. If the forecast holds, the Met Office will be able to confirm one for Greater Manchester after the temperature sequence from Thursday through Tuesday.
The same forecast also shows a wider split across the UK. Wet and humid weather is expected across the north and west on Wednesday and into Thursday, while many parts of southern and eastern England are likely to see temperatures high enough to meet heatwave thresholds by the end of the week.
UKHSA heat-health alerts
The UK Health Security Agency issued yellow heat-health alerts across four regions in England from 3pm on Wednesday, June 17 until 8pm on Monday, June 22. The alerts cover the East Midlands, East of England, London and South East England, but not Greater Manchester or other western and northern parts of England.
The Met Office said the conditions are likely to become more widely settled as the weekend approaches, and the warm spell is expected to peak in the south and east. The UK also saw 32C forecast by the Met Office, while hot weather can bring dehydration, overheating, heat exhaustion and heatstroke.
Dementia and hot weather
Angelo Makri, senior knowledge officer for wellbeing at the Alzheimer's Society, urged people to support those at higher risk as temperatures rise. He said: "People should absolutely enjoy the warmer weather, but it’s important to remember that high temperatures can pose serious risks for people living with dementia if they are not supported to stay cool and hydrated."
He added: "People with dementia may not always recognise when they need a drink or wear suitable clothing, which can increase the risk of dehydration and heat-related illness. As temperatures rise this week, we’re urging families, friends and carers to check in and"
