Climate change - first temperature data for 2026

I have incorporated the first set of temperature data for 2026 in my Climate change database.

The data source is https://www.ecad.eu/dailydata/ and there is currently data until April 2026.

The graph below shows the data for Santander Airport (north of Spain) April 2025 (green line) compared to April 2026 (blue line).

Note that on average 2026 is warmer, with a peak value of 32.8 degrees Centigrade on April 6 (early Spring) 🥵
