NOAA-20 & Suomi-NPP See Ocean Heat Wave off New Hampshire
In the Gulf of Maine, which stretches from Cape Cod to southern Nova Scotia, a “marine heatwave” sent temperatures toward record-highs in August 2018. This visualization uses data from NOAA’s polar-orbiting satellites to map areas where August 2018 sea surface temperatures had been warmer or colder than average. Warm sea surface temperatures help transport more heat energy and moisture into the atmosphere. The persistent warm waters off the coast of the northeastern U.S. and Canada in August 2018 contributed to record-warm overnight temperatures and high humidity levels in New Hampshire.
