None of these are Hot Rock at the end of Feb, it's winter. We live in Sardinia and climb all year round, at the end of Feb in the sun at low-lying crags in the sun like Quirra, Villasimius, Campo dei Miracoli if I look back at the routes I climbed this Jan-Feb-Mar. There is a new guide to Sardinia, the 5th edition of Pietra di Luna, the first new guide to the whole island for 9 years, with twice the number of routes (3600) compared to the last guide. The FAQ's in this guide tell you about the weather for climbing and you can also see them at
http://www.sardiniaclimb.com/NuovoscEng/FAQ/meteo/meteo.html . This guide should be available soon in the UK (you can buy it already in Germany), it was published 10 days ago. I have some copies already since I translated it.
