When to burn Bermuda field

Due to wet weather and more rain coming, I sprayed my Bermuda field with glyphosate 3 weeks ago even though it was still pretty cool temps. Because of the cool temps the burn down did not work perfect. So I sprayed again this Friday. What is the earliest you would burn the field. Also the Bermuda really started to green up today. Night time temps this coming week are to be in the 30s and 40s. What are y’alls thoughts ?
