So many of those stations in the Keys came online in the winter of 2019-2020. So there's only a few years of summer data with them to begin with. So all of these low 90s readings may be typical. CNN is such a hype machine.
Meh...that station came online Nov 2019. It has routinely hit 95-97F in June/July since then.
I remember water temps offshore around Fort Myers Beach being frequently 92-93F when I was down there in 2007. It was 93F yesterday.
