I'd agree-daylight shortening quickly now, gets harder as you enter late August and with cooler weather this week that takes us to 8/22 and beyond before any return to heat.
some burn here too and I'm 5 miles inland from the sound. I also have salt on my south facing windows... Nothing like what you're describing but you all face the open Atlantic vs the sound.
apparantly the 12zUKie looks similar to the 12z GFS-into FL and then mostly inland once to SC. A non event for us verbatim outside of some heavy rains etc.
