Beaumaris weather today, as shown in the live forecast above, reflects the typical coastal conditions of Port Phillip Bay: mild, changeable, and often influenced by afternoon sea breezes that keep summer temperatures cooler than inland Melbourne.
What drives the local forecast?
Beaumaris sits on the eastern shore of Port Phillip Bay, so its weather is moderated by the water. The Bureau of Meteorology’s observations from nearby Moorabbin Airport provide the most reliable data, but the bay can create localised cloud and wind shifts not always captured by inland readings.
- Summer afternoons often see a cooling south-westerly sea breeze arrive by 2–3 pm, dropping the temperature by 3–6°C in minutes.
- Winter minimums hover around 6–8°C, with frost rare due to the coastal influence and proximity to the bay’s warmer water.
- Rainfall is spread evenly through the year, averaging about 600 mm annually, with no pronounced wet season.

How does Beaumaris Beach affect conditions?
The beach itself faces north-west, sheltered from the dominant southerly swell, but the open exposure to the bay means wind and tide can shift the local feel quickly.
- Onshore winds from the south-west or south push cool, moist air directly over the beach, often dropping the apparent temperature by 2–3°C compared to the official reading at Moorabbin.
- Offshore northerly winds in autumn and spring can bring warmer, drier air to the foreshore, making it feel noticeably milder than suburbs just 2 km inland.
- If you’re checking Beaumaris weather hourly, pay close attention to the wind shift around midday — that’s when the sea breeze typically develops.
Is Beaumaris weather the same as Beaumaris Tasmania?
No — they are different locations. Beaumaris, Victoria (this page) is a bayside suburb of Melbourne. Beaumaris, Tasmania is a small coastal hamlet on the island’s east coast, with significantly cooler, wetter conditions year-round.
Where can I see a Beaumaris weather 14 day forecast?
Our 10-day forecast page covers the broader Melbourne region, which applies well to Beaumaris. For a true 14-day outlook, the Bureau of Meteorology’s long-range forecast is the most reliable source — we link to it below.
Why does Beaumaris temperature often feel cooler than the forecast?
The sea breeze from Port Phillip Bay is the main reason. Even on a 28°C day, a south-westerly wind off the 18–20°C water can make the beachfront feel 22–24°C. Always check the wind direction alongside the temperature reading.
