My RES has an outdoor swimming pool. It's 6' in diameter and about 15 inches deep. It's about 3/4s full and has three secure rock formations for basking on or lurking under. The pool is also partially shaded. Pierce is a little guy, a little over 4 inches now, and he just loves it.
So far I only put him in the pool if the water temp is at least 70. His indoor tub is about 75. And the temp outside has always been above 75, with some of the basking sites at the low 90s. I only put him outside when I am home, so I can check on him frequently or just sit back watch.
My question is, what are the suggested temperatures for him to be outside in? Is there a minimum and maximum temp? I live in northeastern Wisconsin, so it hasn't gotten that hot yet, chilly is a different story.
Can he be out in the rain? Obviously the wild ones are. But can a brief downpour alter the temp of the water so drastically that it can be dangerous to him?
Any advice would be appreciated. Maybe I'm looking in the wrong places, but I have yet to find any answers.
Thank you!
