Overview
- The Met Office confirmed a provisional 37.3°C at Santon Downham on Friday, marking the hottest June day on record and the third consecutive daily June record this week.
- The heat forced hospitals to declare critical incidents, closed schools and attractions, led to a Kent hosepipe ban and was linked in reporting to at least six drowning deaths during the spell.
- Weather has begun to moderate as a westerly flow brings thunderstorms and heavy showers, with amber heat and thunder warnings still active in parts of south‑east England and travel and flight disruption reported.
- Medium‑range model runs show a plausible renewed multi‑day heat surge in early July with some maps indicating highs near 38°C in parts of England, though forecasters note such projections carry uncertainty and the Met Office is the operational guidance.
- Separately, local U.S. forecasts warn of a dangerous heat build‑up for the eastern U.S. ahead of the Fourth of July with heat indices possibly topping 100–105°F and likely Heat Advisories or Extreme Heat Warnings.
