Check the live forecast above for today’s conditions in Glendale, then plan your day around the sea breeze that often arrives by mid-afternoon. Glendale’s coastal Hunter location brings mild winters and warm summers, with Lake Macquarie moderating temperature swings.
What drives Glendale’s daily weather?
The main influence is the coastal trough and sea breeze. In spring and summer, north-easterlies develop during the day, cooling the suburb compared to inland Hunter towns. Overnight, the lake can keep minimums a degree or two warmer than nearby Newcastle. For an hourly view, refer to the glendale weather hourly data in the live panel above.
Typical seasonal conditions
Summer maximums usually sit in the mid-to-high 20s °C, with occasional heatwaves from inland air pushing past 35 °C. Winters are mild, with overnight lows around 6–8 °C and daytime maximums of 16–18 °C. Most rain falls in autumn and early winter, brought by east coast lows. The glendale weather radar (available from the Bureau of Meteorology) is useful for tracking these systems.
Does Glendale get much rain?
Yes, annual rainfall averages about 1,100 mm, with a wetter period from March to June. Thunderstorms and east coast lows can bring intense downpours, especially in spring.
How does Glendale compare with Newcastle weather?
Very similar, but Glendale is slightly inland so it can be 1–2 °C cooler overnight and a touch warmer on summer afternoons before the sea breeze arrives. For that comparison, check our Sydney Weather page for regional context.
Is a 14-day forecast useful in Glendale?
It gives a broad trend, but local conditions can shift quickly with sea breezes and troughs. The glendale weather 14 day forecast above is best used as a guide, not a day-by-day plan.
