Check the live forecast above before you head out, because Raby can swing from clear to stormy quickly—especially in summer. This south‑western Sydney suburb sits inland enough to feel hotter than the coast, so plan your day around the risk of afternoon thunderstorms and always carry water.
What is the weather pattern in Raby?
Raby has a humid subtropical climate with warm to hot summers and mild winters. Most rain falls from late spring through autumn, often as short, heavy downpours. Winter days are crisp but sunny, with overnight temperatures occasionally dropping below 5°C. The region’s position relative to the coast means Sydney weather can differ; Raby is usually a couple of degrees warmer in the afternoon.
When should I visit Raby?
The best months are March–May and September–November, when humidity is lower and skies are more settled. Summer (December–February) can be uncomfortably hot, with a high chance of storms. If you’re escaping the winter cold elsewhere, June–August are fine for daytime walks—just pack a warm jacket for the evening. Avoid school‑holiday periods if you want cheaper accommodation.
Is it worth checking the radar before driving to Wollongong from Raby?
Yes, because rain that passes over Raby weather radar often moves east toward the coast. Check Raby weather hour by hour before you leave, especially in summer when a clear sky can turn stormy in under an hour.
Does Raby get fog in winter?
Yes, especially in June and July on calm, clear nights. The fog usually clears by mid‑morning. If you’re commuting to Raby weather hourly shows visibility improving after 9 a.m.
How does Raby compare with Wollongong weather?
Raby is inland and usually 2–3°C warmer in summer and slightly cooler in winter. Wollongong weather is moderated by the ocean, so it rarely hits extremes. Raby gets less coastal wind but more thunderstorms.
