In reply to Removed UserGRUMPY MONKEY:
I went to Rocklands last year and toured the western cape from July through August last year. Climbing was great. Rocklands/Clan william climate was cold mornings but warmed up. Nights can get very cold. had a few days of rain but generally just made them rest days. think in the 25 days were were there had 5 days with rain , but even then only 1 lasting all day.
ON the coast further south (garden route area), had a lot more rain but was told by locals it was unseasonally wet and cold then
