Does hot weather change oil pressure a little, I noticed my pressure was a little lower at idle than usual. It was very humid, it was at the 40 mark.

It shouldn't! But it could if your oil viscosity is low (ex. need oil change).
I assume you use synthetic, so therefore it should maintain it's viscosity at high temps. Certainly higher than what the outside temp can throw at it.
Maybe it's time to change your oil.

My ACR runs 50 - 70 with factory fill.

how about at idle, it usually runs a little higher. it was at 40 at idle.
