UK weather forecast – Met Office warns of dangerous 33C Bank Holiday heat as families hit the road in temperatures matching Hawaii

FORECASTERS are warning of potential dangerous Bank Holiday heat this weekend – as temperatures match Hawaii.

Thermometers could hit a record-breaking 33C in parts as families hit the road for the last long weekend before Christmas.

And the rain should stay away across much of the UK as we see off summer with a final flurry of blistering sunshine.

But the Met Office have issued a level 2 heat alert across parts of southern and eastern England – warning off a potential health hazard.

They say there is a 60 per cent probability of “heat health criteria” being met between Saturday evening and Tuesday morning.

This means there is a strong chance that the warmth will be detrimental to the health of some people – putting local authorities on alert.


A spokesman said: “High pressure will start to build over the south of England, allowing temperatures to gradually rise into the weekend, with the warmest temperatures in the south and east of England.

“Maximum temperatures on Saturday are likely to be near the threshold, but then a warm night is expected on Saturday night, with temperatures reaching thresholds from Saturday evening and onwards.”

Forecasters said the warning system is an important alert for social and healthcare services to act to reduce harm from a potential heatwave.

A 33C heatwave is forecast to strike on Sunday and Monday – which would smash the UK’s record for the hottest ever August Bank Holiday.

That would top the 32C expected in Honolulu, Hawaii, over this weekend.

But as millions prepare to take to the road for short breaks, experts have warned the hot weather could cause more breakdowns.

RAC spokesman Rod Dennis said: “With summer returning in time for the weekend for many of us, it’s going to mean millions of us take to the road for day trips and short breaks.

“Unfortunately, as the temperature rises so can the chances of a breakdown – so it’s important drivers check over their vehicle before setting out.

“Tyre pressure and tread, as well as oil and coolant levels, should all be looked at and doing so can really cut the chances of breaking down.

“Hungry, thirsty or tired passengers can also be recipes for in-car irritability – and ‘carguments’ – so pack enough food and water to keep your passengers happy, and plan in enough breaks along the way.”


The expected 33C heat by Monday would smash the previous high set two years ago – by as much as five degrees.

Chief Met Office meteorologist Steve Willington said: “By Bank Holiday Monday itself temperatures will rise further with around 33C possible in the southeast – which would set a new record for the coming Bank Holiday weekend.”

The current highest temperature on record for the August Bank Holiday Monday is 28.2C at Holbeach, Lincolnshire in 2017.

But the hottest overall temperature during the late summer Bank Holiday weekend is 31.5C, on August 25, 2001, at Heathrow.


A sunny long weekend will be welcomed by Brits bored with the cooler and damper weather we have seen for the past few weeks.

The blast of hot air follows June and July roasts which saw 34C on June 29, at Northolt, north London, and the 38.7C hottest day since records began 178 years ago in 1841, on July 25, in Cambridge.

Met Office forecaster Grahame Madge said: “The August Bank Holiday record is 28.2C and that will easily be challenged. Above the high 20s is quite possible in the odd spot.

“The high 20s are forecast reasonably widely.

“There is also a low chance of beating the overall August Bank Holiday weekend record of 31.5C.

“The fine Bank Holiday weekend will provide a good opportunity for people to be outside after a very wet August.”

There will be showers in northern areas of the UK on Friday, with isolated outbreaks of rain also expected in some southern areas before high pressure moves in, bringing warmer and drier weather.

Friday morning will be dry and bright for most, but there will be extensive cloud and the odd light shower in Wales, the Midlands and North West England.

It will also be cloudy with rain in parts of Scotland.

Central and southern England are expected to see the warmest weather of the bank holiday, while temperatures across northern areas of the UK will be lower, with conditions likely to be more changeable.

Temperatures are forecast to build until Sunday, meteorologist Emma Smith said.
