Sounds like Louisiana...I've pretty much taken to staying indoors from May-September. Can't wait for the "winter"... I bow hunt, the season starts this weekend, and it's still normal for the temps to be in the high 80s until October... I'll be wearing shorts and a t-shirt under my leaf suit. The only thing that makes being outside tolerable is the chance of seeing deer, which peaks in the early morning and late evening, when it's not that hot. I HAVE to come out in the early mornings during the summer to move cameras and recover cards, but don't like it. I do almost all my brush trimming in March, risking the wasted effort (ie, no deer activity spotted around a given spot) to avoid doing the work later in the summer. I do the occasional half-day canoe trip as well, usually on a local stream 15 minutes away, leaving early and coming home in time for lunch... the way the sun is angled on that N/S flow, it's shadier too, but I still go through about a quart of water every hour...
The winter makes up for it though... I start getting comfortable with temps (for hunting early/late) by mid October (when gun season starts), and can go back to camping on the ground (vs hammock, for heat, bug, and snake protection) by November, and continue through April... 5 months isn't too bad. But by May, it's a struggle to get outside again during the squirrel season, and by the end of May, I stay inside again. I can also canoe all during that time (though hunting is my main activity from Sept through November), and you won't die if you fall in the water in January... not too scenic then, but still nice to be out on a clear dry day.
Two years ago, I aborted one day into a 4-day trip in the Adirondacks because the expected norm (high 40s for lows, and high 60s for highs) wasn't even close... it was in the mid 80s... I was horribly disappointed, but I just couldn't do it, physically.
Tried again on what turned out to be a bad overnighter (supposed to be Friday-Sunday) a couple weekends ago... paddled to a new spot on Toledo Bend Lake (hour away) with a couple friends. Humidity was indescribable. I came in by noon on Saturday, and it took two solid nights of good sleep to recover from the one bad night... horrible. I've learned. I'm no longer a spring chicken, I work in a building kept at low humidity and about 65* via A/C, and it's had a detrimental effect on my ability to deal with the heat and humidity.
Looking forward to October.
