Mentone, on Port Phillip Bay’s eastern shore, is in for a mild and partly cloudy day. The live forecast above shows a top of around 22°C, with light south-westerly breezes keeping the bay-side air fresh. No rain is expected, making it a good afternoon for a walk along the Mentone Beach foreshore.
What’s driving Mentone’s weather pattern?
A high-pressure system sitting over the Tasman Sea is directing a stable north-westerly flow across Melbourne’s bayside suburbs. This keeps Mentone dry, with low humidity and clear skies overnight. A weak trough moving in from the west may bring a few more clouds by late afternoon, but the Bureau of Meteorology’s mentone weather bom observations show no significant change for the next 24 hours.
How does Mentone’s bay location affect conditions?
Mentone sits directly on Port Phillip Bay, so sea breezes often moderate summer heat and can bring cooler air in from the water during spring. This local effect means temperatures here can be a degree or two lower than inland suburbs, particularly in the afternoon. For those checking a mentone weather hourly forecast, expect the coolest conditions between 3pm and 6pm when the south-westerly wind is strongest.
Does Mentone get much rain?
Mentone averages around 600 mm of rain annually, with the wettest months typically from May to October. Winter fronts bring most of the rain, while summer is usually dry with occasional thunderstorms.
Is the water warm enough for swimming in summer?
Port Phillip Bay water at Mentone Beach reaches around 18–22°C in January and February. It’s comfortable for swimming, though a wetsuit is often preferred by surfers. The bay’s sheltered position means low swell.
Can I see a mentone weather radar?
Yes, the Bureau of Meteorology’s Melbourne radar (Mount Dandenong) covers Mentone. It’s the best tool for tracking rain bands moving in from the west or south-west. You can access it via the BOM website.
