Check the live forecast above before heading to Mordialloc Beach. Afternoon sea breezes often cool the coast, so pack a layer even on warm days. Rain is most likely in the morning, and the bay can kick up a stiff breeze by lunchtime.
What is the typical weather pattern for Mordialloc?
Mordialloc sits on Port Phillip Bay, about 22 kilometres southeast of the Melbourne CBD. Summers are mild to warm, with average maximums around 25°C, and winters are cool, averaging 13–15°C. The bay moderates extremes, so you won’t see the inland heatwaves that affect other parts of Melbourne weather.
Rainfall is fairly even through the year. The wettest months are usually October and November, while January and February are the driest. Fog can form on calm winter mornings, especially if you’re checking the Australia weather hub for details on visibility.
How reliable are the 10-day and 14-day forecasts for Mordialloc?
The weather in mordialloc 10 days forecasts give a useful trend, but day-to-day accuracy drops after day 7. For the most reliable view, check the mordialloc weather bom page directly, as the Bureau updates its model several times a day. A mordialloc weather 14 day forecast is best used as a general guide—expect shifts as the date gets closer.
If you need up‑to‑the‑minute rain, use the mordialloc weather radar loop. It shows showers moving in from the bay, which can arrive suddenly. For an hour‑by‑hour breakdown, the mordialloc weather hourly table on BOM or WillyWeather is more useful than a daily summary.
When is the best time to visit Mordialloc Beach?
December to February offer the warmest water and calmest days for swimming. Sea breezes pick up after 2 pm, so morning or late afternoon are most comfortable. Check the live forecast above for wind speed before you go.
Does Mordialloc get fog often?
Yes, especially in winter when the bay is warmer than the land. Fog usually clears by mid‑morning, but it can lower visibility for early walks along the beach. The mordialloc weather radar will show if any fog banks are lingering.
Where can I find the latest Mordialloc weather warnings?
The Bureau of Meteorology issues coastal wind warnings and severe weather alerts for Port Phillip Bay. Check the severe weather warning page for any current advisories that may affect Mordialloc.
