The Met Office has issued an Amber heat warning for southern and eastern England, with the alert set to last into next week. The warning comes as betting markets show near-certainty that temperatures will break the UK's June record, with Polymarket toss odds hitting 99.95%.
Why the warning was issued
The Amber warning covers a wide swath of the country, from the south coast up through East Anglia and into the East Midlands. Forecasts show a prolonged period of hot weather, with temperatures expected to climb well above seasonal norms. The Met Office advises people to take precautions, especially those with health conditions or who are vulnerable to heat stress.
What the betting odds mean
Polymarket, a prediction market platform, now gives a 99.95% probability that a new June temperature record will be set. That's as close to a sure thing as markets get. The previous June record for the UK stands at 35.6°C, set in 1957. If the warning pans out, that number could be eclipsed within days.
Wimbledon 2026 forecast
Looking further ahead, climate models for Wimbledon 2026 suggest temperatures could top that same June record. While the tournament is held in July, the forecast points to a broader warming trend. Organizers are likely to review heat policies for players and spectators, though no official changes have been announced yet.
The current heatwave is not expected to break until early next week, when a cold front may bring some relief. For now, residents and visitors in the affected areas are urged to stay hydrated, avoid peak sun hours, and check on older neighbours.
