Staying in the shade is one of the most effective ways reduce exposure to the sun. Shade can be either:
Natural: trees, hedges and other vegetation
Constructed: permanment or portable shade
Building good quality shade
The amount of shade protection a fabric provides is expressed in terms of its ultraviolet protection factor (UPF) rating. (AS/NZS 4399:1996.). Shade cloths made from tightly woven fabrics that have been given a UPF rating can provide protection from as much as 97% UV radiation.

Look for shade that provides at least 94% protection (UPF 15) from direct UV radiation and creates an environment that is comfortable to use in both summer and winter.
Whatever you use for shade, make sure it casts a dark shadow and that it allows for daily and seasonal sun movement.
In many situations combining built and natural shade will be the best option.
