Bob,

Thanks for thoughts on sea breezes and thermals which makes sense to me. I had overlooked the fact of the relatively shallow depth of the Gulf. Lake Michigan's average depth of over 200 feet keeps the core temp of the deep water at 40F. This means that the wind can blow the warmer surface water away and the cold water will well up in its place. The Northern part of the lake stays cold 50F to 60F making it great for thermal flows on shore all summer.

Looking ahead, I hope we can continue this dialogue on sea breezes. Maybe you could post up when you think them likely as the season progresses. Or send a windy text. I generally watch the meters before going, but as you say in your post I could miss some sessions following this routine. Am used to more predictable thermals on Lake Michigan and in Corpus.

Regards,
Tim
