Europe bakes under second-hottest May on record as heat dome turns continent into 'new normal'

The world just sweated through its second-hottest May on record, and Europe got the worst of it.

The EU's climate monitor, the Copernicus Climate Change Service (C3S), dropped the news on Wednesday. Last month, a "heat dome" — a massive bubble of hot air that parked over the continent — dragged temperatures way above normal. Britain, France, Ireland, and Portugal all broke national records for May.

This wasn't your usual spring warmth. The heat came from northern Africa, where a pool of superheated air drifted north and just sat there. That's what a heat dome does: it traps hot air under a high-pressure system, turning the sky into an oven lid.

C3S director Carlo Buontempo didn't mince words. He said climate extremes are becoming the "new normal" on the continent. The monitor has been tracking global temperatures since 1940, so this isn't a small sample.

The only year that beat May 2026 was May 2024 — which itself was part of a 12-month streak of record-breaking global heat. That streak ended only recently, but the underlying trend hasn't let up.

What does this mean for regular people? In Europe, it means more early heatwaves that catch cities unprepared. Many homes don't have air conditioning because it's never been this hot this early. Hospitals see a spike in heat-related emergencies. Farmers watch crops wilt before summer even officially starts.

Globally, May 2026 was 1.5°C warmer than pre-industrial levels, according to C3S data. That number matters because 1.5°C is the limit countries agreed to aim for under the Paris climate accord. The world isn't past that limit permanently — yet — but every hot month edges closer.

Copernicus uses billions of measurements from satellites, ships, aircraft, and weather stations to build its temperature record. The data is public and widely used by scientists and governments.

The heat dome that cooked Europe in May has since weakened, but the season is just starting. Meteorologists expect more extreme heat through June and July. The same weather patterns that drove the May heat — a wobbly jet stream and warm Atlantic waters — are still in place.

For Filipinos, this story hits close to home. The Philippines has seen its own brutal heat this year, with several cities declaring a state of calamity due to extreme temperatures in April and May. The same global warming that bakes Europe also makes typhoons stronger and dry seasons longer in Southeast Asia.

So what's next? The C3S will release its June data in mid-July. If the pattern holds, Europe could be in for a long, hot summer. And the world will keep watching those temperature numbers creep up.
