In reply to Will Rupp:
In February 2012 in Marrakech it felt like a pleasant sunny summer's day here in Glasgow.
We arrived in Morocco again in June 2013. The temperature at menara airport in Marrakech was 41C in the shade and getting off the plane felt like stepping under a grill. To be fair it was a dry heat, and bearable, but hot it most certainly was and hot overnight too even in Asni at about 1000m (?) At altitude on Toubkal it was still very,very hot by UK standards and the potential for sunburn very high...I had my foot outside my tent for about 10 minutes and it really burnt ( I'm pretty pale though).
I'd be looking for shade, early morning and probably shortish routes or bouldering. Long sleeves, long trousers.
Or go at a different time of year.
