Not only was July 2023 the warmest month on record with the highest SSTs on record, it had the highest average dew point of any July (and month) on record. Blues represent record high dew points. Of course over water this is highly correlated to SSTs. Still, it was a wet heat. pic.twitter.com/ZxDGWFim83
