Check the live forecast above before heading out. St Andrews sits inland in south-western Sydney, so its daily weather often runs hotter and more extreme than conditions nearer the coast.
How hot does St Andrews get in summer compared to Sydney weather?
St Andrews is usually 3–5°C hotter than the Sydney CBD on summer afternoons. Without the coastal sea breeze, the heat builds up through the day. Always check the local St Andrews report rather than relying on the broader Sydney weather page, as conditions can be quite different.
What brings the biggest weather risks to St Andrews?
Summer thunderstorms are the main hazard. St Andrews sits near the Georges River and local escarpments, which can trigger rapid storm development. Keep an eye on the live forecast above, and if severe storms are predicted, check the Severe Weather Warning page before travelling.
Is St Andrews weather similar to Campbelltown weather?
Yes. St Andrews and Campbelltown share the same local climate zone in the Macarthur region. Conditions are nearly identical, so checking the Campbelltown weather forecast is a reliable way to plan your day in St Andrews.
Does St Andrews get much rain?
Rainfall is moderate, averaging around 700–800mm per year. Rain is fairly evenly spread, though late summer and early autumn often bring the heaviest falls from thunderstorms.
Are heatwaves common in St Andrews?
Yes, heatwaves are a regular summer risk. The inland location means several consecutive days above 35°C are not unusual. Check the live forecast above and stay hydrated on extreme heat days.
