Caught some fun surf last Friday and the water was close to 60. Paddled out today on Long Island and it seemed like the water temperature had dropped at least 5 degrees. Literally got light ice cream headaches after two duck dives. Didn't wear boots or gloves but my hands and feet were borderline going numb. I know that front brought north winds and cooler temps, but it's been like 90 for the past week. Anyone else notice a large drop in water temps overnight? Maybe some type of upwelling?
