What is driving today’s conditions in Kentlyn?
A weak trough over the NSW South Coast is drawing moist easterly winds across the Sydney basin. Kentlyn, situated at the foot of the Illawarra escarpment, often receives more cloud cover and slightly higher humidity than the coastal suburbs. Expect a morning low near 15°C, climbing to around 25–26°C by early afternoon before a 40–50% chance of a brief shower arrives. Winds will be light, generally 10–20 km/h from the east.
How does the weekend outlook compare?
Saturday will be similar — partly cloudy with a top of 27°C and isolated showers possible. Sunday brings a change: a firmer south-westerly wind will clear the sky, dropping humidity and lifting temperatures to a warmer 29°C. Overnight lows will stay around 14–16°C both days. For broader context, see our Sydney Weather page for regional trends.

Does Kentlyn ever get severe storms?
