Guildford, in Sydney’s west, currently sees mild conditions as shown in the live forecast above; you can expect a typical western Sydney pattern of warm days and cooler nights, with the chance of an afternoon shower or thunderstorm in summer.
What is the typical weather pattern for Guildford NSW?
Guildford sits in Sydney’s Cumberland Plain, so it gets hotter than the coast in summer and cooler in winter. The Bureau of Meteorology (BoM) records show January averages around 28°C, while July averages near 17°C. Rainfall is spread fairly evenly across the year, though late summer and early autumn often bring the heaviest falls from east coast lows.
- Summer (Dec–Feb): Hot and humid, with maximums often above 30°C. Afternoon storms can develop quickly.
- Autumn (Mar–May): Warm days, cooler nights. Mist and fog are common in the early morning.
- Winter (Jun–Aug): Cool and crisp. Minimums can drop to 3–5°C, with frost possible in low-lying areas.
- Spring (Sep–Nov): Warming up, with variable winds and occasional thunderstorms.
How does Guildford weather compare to the Sydney CBD?
Because Guildford lies 22 kilometres west of the coast, it misses the sea breeze that cools the CBD in summer. Afternoon temperatures here can be 4–6°C higher than at Observatory Hill. Conversely, winter nights are often 2–3°C colder, with fog lingering longer in the morning.

Is Guildford affected by east coast lows?
Yes. East coast lows can bring prolonged heavy rain and strong winds to Guildford, most often in late autumn and early winter. These systems can cause localised flooding in low-lying parts of the suburb.
