Mine just started to die down yesterday after being unbearable for 5-7 days. Give it a week. The pollen is bad here too. Sheets of yellow-green everywhere.
You're definitely a cool spot. 77.7F there today and I had 77.9F. Some summers I struggle to hit 90F...will be interesting to see if you can pull one off.
It mixes the dews out Sunday afternoon, but by evening it has them well into the 60s. I’d be wary of that and lean toward higher theta-e pooling as well.
