Creating effective shade
SunSmart's guide for assessing shade needs and creating effective shade
Why is shade important?
Too much UV can cause sunburn, tanning, skin and eye damage, and skin cancer.
Shade can reduce UV exposure by over 90%, but this only occurs when exposure to the sky is eliminated. Typical shade, such as a tree or umbrella, reduces UV exposure by up to 75%. This means that 25% or more of UV still reaches you, from reflection off the sky or surrounding surfaces. As a rule of thumb, if you can see the sky, you are less than fully protected.
For the most effective UV protection, combine shade with protective clothing, a broad-brimmed hat, sunglasses and SPF 30+ sunscreen.
Currently, many outdoor facilities and venues in Victoria have inadequate or ineffective shade. It is important to advocate for the creation of effective shade at these venues to:
- reduce the risks associated with UV overexposure
- create cool, comfortable outdoor environments for physical activity and recreation.
This resource provides a step-by-step guide to developing high-quality, UV-protective shade in Victoria.
The ideal shade scenario
SunSmart (Cancer Council Victoria) recommends outdoor spaces include:
- sufficient shade to protect all people when the UV level reaches 3 and above. In Victoria this is generally from September to April
- shade that offers at least 94% block-out of direct UV and minimises indirect UV
- a combination of built and natural shade. Built shade structures provide predictable, reliable coverage, while natural shade is aesthetically pleasing and environmentally friendly. Deciduous trees offer the added benefit of providing cool, UV-protective shade when required and dropping leaves in winter, allowing sunlight to warm and brighten your outdoor space
- shade that is easily accessible, attractive, in good condition and regularly maintained.
The ideal shade scenario may not be achievable right away. However, the steps in this guide will help you:
