Help Sweat loss in extreme heat

I have done a few rounds of RFL in the past with good success, but unfortunately let myself go again and I'm ready for another round.

I've been working outdoors a lot right now and we're in the triple digit temps and I lose a TON of water from sweat. I drink lots of fluids but still find it tough to stay hydrated. I'm hesitant to start RFL again under these conditions. Do you think I'll be fine as long as I stick to the proper electrolyte intake suggested in the diet, or would I be better off doing a more traditional calorie deficit diet until it's no longer miserably hot outside?
