Valencia swelters through 30C nights as cooling bills hit €150

It doesn't matter if the official thermometer reads 33 or 34 degrees in the shade: in Valencia, with asphalt burning and humidity above 80%, the street feels like 40. The problem is no longer the high. It's the low.

Nights with no relief

Two months of lows of 25 or 26 degrees that aren't even reached at dawn: they hit at six or seven in the morning. And this week the record came: 30.9 degrees, the highest minimum since records began. With that temperature and sticky humidity, sleeping without air conditioning is for heroes or reckless people.

The cost of cooling a home

The electricity bill has gone from 70 euros to more than 150 in a flat with a good energy rating. The extra 80 euros are, literally, the price of being able to sleep. Some have installed their first air conditioner this summer after thirty years of putting up with it: statistics won't show it, but it's a behavioural data point. Air conditioning is no longer a luxury; it's a mandatory expense.

Tourism fleeing north

The heat doesn't just inflate the bill. It's starting to shift the map of housing and tourism. While the Mediterranean becomes a deep fryer, prices on the Cantabrian coast — Asturias and Cantabria — are rising fast. Wealthy buyers who owned homes in the south or the islands are considering selling and buying in the north. It's not a fad: it's an incipient phenomenon of climate migration.

CO2 and solar cycle: a fight that doesn't cool things down

Behind so much heat, the usual debate: CO2 versus solar cycle. The hottest years, 2016 and 2020, coincided with low solar activity, and solar advocates use that data to dismantle the CO2 narrative. The other side responds that emissions keep rising and that the atmosphere didn't notice the lockdown. Each side picks the thermometer that suits them best. Meanwhile, the asphalt burns.

The night at 30.9 degrees can be explained by the ponentada, El Niño or solar radiation. The 150-euro bill cannot be explained: it is paid. Valencia's summer has ceased to be a weather topic and become a problem of family economics. And that, neither the solar cycle nor CO2, will fix in the short term.
