If, like me, you have been caught out with a wardrobe still full of jeans and light jumpers, you will have been hit by this Costa Blanca heatwave, which seems to have come out of nowhere.
I am sure there is normally a more gradual transition from spring to summer, giving us all a bit more time to adjust. However, this year the weather seems to have other ideas. Honestly, it feels more like late July than the beginning of June. Already, my ceiling fan is working overtime at night, and I am checking the pavement before taking my dog for a walk.
Is the Costa Blanca really experiencing a heatwave?
As is typical with the weather, it has now become a topic of conversation, with comparisons to previous years made by those who have lived here for a while. “It’s getting hotter every year” is a phrase often heard over a morning coffee or while waiting in the shade outside a local shop.
As it turns out, comparisons with previous years show that summer has definitely come early to the Costa Blanca. Typically, temperatures are around 26–28°C, with moderate humidity and comfortable evenings. However, recent years have shown a gradual trend towards earlier and more intense heat. Because of the terrible start to spring this year, the intensity of June has caught us even more by surprise.
What’s behind the unusually high temperatures?
Across the region, temperatures are climbing into the thirties, and nights are starting to feel stubbornly warm. Many climatologists attribute this change to the warming of the Mediterranean Sea and broader climate patterns. Meteorologists have also highlighted persistent high-pressure systems across Western Europe that are driving unusually warm air northwards from Africa. Whatever the reason, there is agreement that Spain may be entering one of its hottest summers in recent years.
As June unfolds, it will be interesting to see whether temperatures return to more ‘normal’ levels. One thing’s for sure, though, summer 2026 has wasted no time in making a grand entrance.
