hi, Ive put a link in to a similar discussion below for you,

I dont think youll have a problem with those temps, if you follow the link youll see the sort of climate my worms have survived but find the shadiest spot in the garden you can, my worm farm is under a tree with a fence on two sides so it doesnt get any sun on it at all over summer

Here is a link that might be useful: heat and worms

I am in the South West, So Cal and we are regularly in the 100's. I have a wooden bed for my worms and I keep it in the shade and have a tarp over it to ease the sunshine. I also go out in the morning and give a light watering if it is going too be a scorcher of a day. I have a watering bucket I keep for just such occasions. my guys don't show any problems with it.

southernsam,

I live in Tupelo, and I have two wormbins in the backyard....Mine are about 4.5' across...So, there's plenty of stuff in the bins to where the worms can move about...Mine are in the shade also....Hope this helps...Dwight
