What temperatures to expect in September/October

[clubman]

Hello

I'm planing my next visit to Morocco, I have 2 possible dates, either from the 21/9 to the 5/10 ( my preferred date ) or from 18/10 to the 2/11.
Now my planned route will start from Midelt, down to the Dades Gorge and further south all the way to Zagora and Mahmid . After will travel east to Merzouga.
From your experience what temperatures can we expect down south in these periods ? in the end of April,early May 2012 max temp was around 32ºC which was nice, but more than this starts to became to much for confort.

Best Regards

Tito
