ACSPO estimates of SSTs in the Gulf of Maine

Clear skies over the Gulf of Maine close to midnight early on 27 Man 2025 allowed for the VIIRS instrument on NOAA-20 to capture a crisp view of the sea surface temperatures over that body of water. Temperatures are cooler than 50oF over the entire Gulf of Maine, with low 40s (magenta in the color table used) hugging the coast of eastern Maine and Atlantic Canada. The coldest temperatures — in the 30s, still! — are over Lake Ontario. At the very southern edge of the scene, the warm waters of the Gulf Stream (just a bit warmer than 80oF) are apparent.
