The United Kingdom is preparing for what could become the hottest May day ever recorded, with forecasters warning temperatures may climb as high as 34C across parts of southern England during the ongoing Bank Holiday heatwave. The extreme conditions have already pushed several regions into official heatwave territory, while health alerts remain active across large parts of the country.

According to the Met Office, temperatures in London, the South East, and parts of the Midlands are expected to rise significantly above seasonal averages, potentially breaking a May temperature record that has stood for more than a century.

UK Already Experiencing Historic Heat

Britain has already recorded its hottest day of 2026 so far.

On Sunday, temperatures reached 32.3C at Kew Gardens in London, making it the hottest May day seen in the UK in nearly 80 years. Forecasters now believe Monday could become even hotter, with a realistic possibility of temperatures touching or even exceeding 34C.

The current official May temperature record stands at 32.8C, recorded in:

Camden Square, London (1922)
Horsham
Tunbridge Wells
Regent’s Park (1944).

Meteorologists say those figures are now under serious threat.

Which Areas Will Be Hottest?

The most intense heat is expected across:

Greater London
South East England
East Anglia
Parts of the Midlands.

Meanwhile, Scotland and Northern Ireland are expected to remain cooler with more cloud cover and occasional showers.

Several locations have already officially entered heatwave status after recording three consecutive days above regional temperature thresholds, including:

Heathrow
Kew Gardens
Essex
Suffolk.

Why This Heatwave Is So Unusual

Meteorologists describe the current conditions as “historic” because temperatures above 33C or 34C are extremely rare in May.

A Met Office spokesperson said temperatures approaching 35C in spring are highly unusual, even compared to typical summer conditions.

The heatwave is being driven by:

Strong high-pressure systems
Clear skies
Dry air
Warm continental airflow moving into Britain.

Climate experts also say global warming is increasing the likelihood of extreme early-season heat events across Europe and the UK.

Health Alerts Issued Across England

Due to the extreme temperatures, the UK Health Security Agency (UKHSA) has issued amber heat-health alerts covering:

London
South East England
East Midlands
West Midlands
Eastern England.

Officials warned the heat could lead to:

Increased health risks for elderly people
Dehydration
Heat exhaustion
Pressure on hospitals and emergency services.

Experts are advising people to:

Stay hydrated
Avoid direct afternoon sun
Wear sunscreen
Keep homes cool
Check on vulnerable relatives and neighbours.

Tropical Nights Could Add to Discomfort

Forecasters are also warning about unusually warm overnight temperatures.

In some areas, temperatures may remain above 20C overnight, creating what meteorologists call “tropical nights” — conditions that can make sleeping uncomfortable and increase health risks during prolonged heatwaves.

Public Rushes to Beaches and Parks

The hot weather has triggered huge crowds at beaches, parks, lakes, and public spaces across Britain over the Bank Holiday weekend.

Coastal towns, public swimming spots, and outdoor attractions have seen major increases in visitors as people attempt to enjoy the sunshine.

However, authorities have also warned about:

Wildfire risks
Water safety dangers
Traffic congestion
Heat-related illnesses.

Perspective

Britain is no stranger to warm summer days, but temperatures approaching 34C in May highlight how unusual weather patterns are becoming increasingly common.

What once seemed exceptional is gradually becoming more frequent.

Whether this heatwave officially breaks the all-time May temperature record or not, it has already entered the history books as one of the UK’s most extraordinary spring weather events.
