As for the heat, I think most Brits that started climbing out here in the 80s climbed in the middle of the summer, in the sun. We were totally clueless and did what we did in the UK! Also summers now are hotter - last year was a slight exception as it seemed to be low to mid 30s most of the time with only a couple of days at 39 - 40°. The previous year was mid to upper 30s with quite a few 40° days.
Climbing on St Julien might just be OK early morning but it holds the sun till quite late in the evening and the rock just radiates heat long after dark!
Have a look here for the VFs https://www.ukclimbing.com/logbook/crags/saint_julien-8845/ The easy one faces SE but the three harder ones are on the north face. I'm not sure if the climbing routes on the north face are in fact still there. My guess is that they might have de equipped due to the VFs.
