My wife and I visited Phoenix last November (JW Marriott Desert Ridge Resort & Spa). We are wanting to go again this year, and have been approved off of work for a week in August, but I am concerned about the heat and humidity. I hear it can be around 40C and 100% humidity.
My wife has Multiple Sclerosis and heat can cause fatigue and other problems. She normally does fine as long as there is plenty of cold water/drinks, pool, shade, and an air conditioned room we can escape to if needed.
I'm wondering if August weather would be too much? I'm sure it's drastically different from November when I think the highest it got was maybe 25C. How can I know? Is it like a sauna? I'm wondering if she'd be OK provided we go indoors sometimes and always use sun screen, sun hat, shaded cabanas, cold drinks, and spend most of the time in the pool?
Also, is it true we can expect a LITTLE rain each day, but it's mostly sunshine? We just had a vacation rained out in the US Northwest and it was awful. We are really hoping for some sunshine!
On a side note, I also posted this in the Puerto Vallarta forums as that is a fallback option for us, and I understand the weather can be very similar there as well (40C, 100% humidity). I guess at this point we want to pick the better if the two in terms of comfort and least chance of rain.
