Global sea surface temperatures (SSTs) in September 2026 shattered the previous September record and were only slightly lower than the all-time record set last month. September is typically the 6th warmest month for SSTs - but this September would have set a record in all but 1 other month. 🔥🔥🔥

How much does normalcy bias affect media reporting?
Here is a chart of global sea-surface temperatures (SSTs) from 1982 to 2026 with the years 2023, 2024 and 2025 omitted.
As of June 27th, global SSTs have set 26 daily record highs in a row.

The Mediterranean is getting warmer, and marine heatwaves are a defining feature of that change.
In 2024, it recorded its highest number of MHW days in two decades.
Mean SSTs reached 1.23°C above the 1982–2024 baseline, rising at 0.32 ± 0.01°C per decade.
