Although this summer has been a bit of a let down there have been days that reached 35 degrees and instead of scurrying off inside to find some summer shade its much nicer to be outside in the dappled shade and enjoying the breeze.
There are as many types of sun shades here in Portugal as there are rainy days in the UK. We have tried just about them all with varying degrees of success. Temporary cloth-covered shades from parasols to garden tents (arbors) are great for the UK where you will use them for a very limited time and the put them away.

Suspended sheets of sail material are attractive but you must ensure that they are mounted into a very solid fixing point if you are mounting them on a Portuguese house you must fix the to the reinforced concrete structure not the bricks as they are just not strong enough A small problem with these shades is that birds tend to mess on top of them and it take a while for these marks to washed off which can look a little off-putting.
