Quiaios, a rocky road to another sunset

Leaving the Italians to voyage on south, I head north, remembering to keep the ocean on my left. It's hot and sticky today, with the ever present head winds.... I thought that the prevailing winds were usually south westerly, but maybe that's only in Ireland. I have the feeling that I have only had one day when the wind was in my favour this whole trip. I also find a few Eurovelo 1 signs... It has been a while. 

The goal is to make 90km today and find a nice dune to experience another sunset. This being Portugal, this task is easily achieved, albeit having to cycle off the beaten track. The beach is completely devoid of people and any signs of civilization.
