I posted similar about UK waters the other day - it isn't as extreme here but it is noticeable, on Wednesday I completed a 2+ hour snorkel (with a wetsuit) when I'm often too cold after an hour.

Last night I snorkelled for 30 minutes with my son at 6pm without a wetsuit for either of us - the sea is that much warmer than average right now.

The heat is impacting the local catch of lobster and crabs, and increasing the number of new fish species here - and of jelly fish.
