What is the 7‑day outlook for Sylvania?
Maximums sit around 22–25°C most days, with a possible 27°C mid‑week if a northerly flow develops. Overnight lows hold near 16–18°C. A trough brings a shower chance on Thursday and Friday; otherwise fine, sunny spells dominate. The 10‑day forecast keeps the pattern stable into the following week.
How does Sylvania’s coastal location affect its weather?
Sylvania sits on the Georges River estuary, about 2 km inland from Cronulla’s beaches. Sea breezes moderate summer heat and keep afternoon humidity lower than western suburbs. In winter, minima are 1–2°C milder than Sydney’s CBD due to the water’s buffering effect. Tides along the river can influence local wind patterns during north‑easterly flows – check Sylvania tides on WillyWeather if boating or fishing.
Is Sylvania weather similar to Sydney’s?
Broadly yes, but Sylvania is 1–2°C cooler in summer afternoon due to the river breeze, and slightly warmer in winter mornings. Rainfall totals match Sydney’s, though localised storms can be more common over the Sutherland Shire.
Where can I get a Sylvania weather 14‑day forecast?
Bureau of Meteorology provides a 7‑day official outlook; for a 14‑day view try Weatherzone or Elders, which extend the pattern using ensemble models. Check the Sydney weather page for the broader regional trend.
Does Sylvania get sea fog?
Occasionally in autumn and winter when warm, moist air moves over cooler coastal waters. The fog usually clears by mid‑morning. Visibility can drop below 1 km near the river, but it rarely affects road travel further inland.
