Camino mozarabe in may

I intended to travel to China in may. Due to the developments concerning the coronavirus the chances that this trip will be cancelled are increasing. In that case I am considering to walk a camino again. The Camino Mozarabe is number one on my "Camino to do list ". I am afraid in may it will be too hot to my liking ( I walked the Via de la Plata from Sevilla beginning the end of March, and it was allready on the limits for me) Perhaps walking on somewhat higher altitudes will diminish the temperature a bit. I understood that day distances are sometimes are more than 30 kilometer, so starting early in the morning does not solve the problem 100 percent. Can anyone tell me what I might expect. I read also that there are few pilgrims on the Mozarabe, is this still the case? Thanks in advance
