Should You Put Shade Cloth Over Your Swimming Pool? (Benefits & Best Setup)

Introduction

During an Australian summer, having a backyard swimming pool is the ultimate luxury. However, high solar exposure comes with distinct challenges: harsh water glare, rapid chemical loss, soaring water evaporation rates, and the risk of severe sunburn for long afternoon swims.

Installing overhead shade cloth or a shade sail above your pool area is one of the most effective ways to lower water temperatures, protect your family from UV rays, and significantly reduce weekly pool maintenance. Here is everything you need to know about using shade fabric around swimming pools in Australia.

1. Overhead Pool Shade vs. Pool Blankets: Know the Difference

Before starting a DIY project, it is essential to distinguish between the two types of pool covers:

Surface Pool Blankets (On the Water): Solar bubble covers sit directly on the water surface. Their primary job is to retain water heat overnight and prevent evaporation when the pool is not in use.
Overhead Shade Cloth Structures (Above the Water): Suspended shade cloth rolls or tensioned shade sails float above the pool. They block direct sunlight, reduce UV exposure for swimmers, cut down water surface glare, and keep ambient air around the deck cooler.

2. Key Benefits of Shading Your Pool Area

A. Maximum UV Protection & Reduced Water Glare

Harmful UV rays reflect off water, doubling sun exposure for kids and families while swimming. High-density 90% shade cloth or commercial-grade shade sails filter out up to 95%–98% of UV radiation, making afternoon swimming significantly safer.

B. Reduced Chemical Burn-Off

Chlorine breaks down rapidly under direct, intense sunlight—a process known as photolysis. By shading the pool surface during peak solar hours (11:00 AM to 3:00 PM), you preserve chlorine levels, keep the water chemistry balanced for longer, and cut down on chemical costs.

C. Reduced Evaporation & Lower Water Bills

In hot regions across New South Wales and Australia, an unshaded, exposed pool can lose up to 50–100 litres of water a day purely to heat evaporation. Overhead shade blocks direct solar heat, keeping the top layer of water cooler and dramatically reducing water top-up frequency.

D. Keeps Leaves and Debris Out of the Filtration System

Overhanging trees drop leaves, blossoms, and twigs directly into the water, clogging skimmer baskets and altering water pH. Suspended shade fabric acts as a canopy, catching falling debris before it reaches the pool floor.

3. How to Choose the Right Material: 70% vs. 90% Blockout

70% Shade Cloth: Best if you want a balance of light shade while keeping the pool environment bright. It allows generous airflow and moderate sunlight filtering.
90% Heavy-Duty Shade Cloth: The standard for pool protection. It delivers maximum thermal insulation, keeps water temperatures comfortable during 40°C heatwaves, and blocks almost all direct UV rays.
Pre-Tensioned Shade Sails: For larger spans across wide in-ground pools, a heavy-duty shade sail with reinforced perimeter webbing and marine-grade stainless steel hardware is ideal for withstanding high wind loads.

4. Pro Tips for Poolside Installation

Angle for Drainage and Air Flow: Never install pool shade fabric completely flat. Angle the canopy at a minimum 20° slope so rainwater runoff doesn't pool in the center.
Maintain High Clearances: Mount fixing points high enough (at least 2.5m to 3m) to keep the fabric well clear of active swimmers and pool equipment.
Upgrade the Pool Deck Area: Combine your overhead canopy with permeable, quick-draining artificial turf around the pool coping. It creates a soft, non-slip, mud-free area for lounging that stays cooler underfoot than concrete or dark paving tiles.
