It's been mostly pleasant here, I think my GPS maxed out at ~89f, but it was closer to 75 for most of the ride.
It's been in the middle 80's here for a few weeks. I still bike commute, but I sure do get more damp doing it.
Nothing at all like the high 90's low 100's where I used to live. That wasn't pleasant from about 9:30am until about 6:30pm.
90f is fine for me, if the humidity is low. 85f with high humidity I tend to keep rides under 30 miles unless I have something planned.
