Heat Record: Global Temperature, 1948–2026

Earth's surface temperature, mapped every month from 1948 all the way to right now — then continued day by day through the record heat of July 2026.

White marks 14°C, Earth's long-term average — red is hotter, blue is colder. That's why the map visibly pulses with the seasons: it's the actual temperature, not a deviation from average.
