Somerville’s weather today, based on the live forecast above, is mild with a mix of cloud and sun, and a slight chance of a shower moving in from the bay this afternoon.
What’s driving today’s conditions in Somerville?
A weak trough over central Victoria is drawing moist air across the Mornington Peninsula. The live forecast above shows light north-easterly winds shifting southerly later, which will keep the coast a degree or two cooler than inland spots such as Frankston.
- Expect a partly cloudy morning, then the chance of a light shower near the bay from mid-afternoon.
- Winds will stay under 20 km/h most of the day, so it’s a calm weather pattern with no coastal warning.
- Overnight, cloud may thicken as the trough drifts south — see the 10-day forecast for the weekend outlook.
- For hourly changes, check the Melbourne weather page, as the city’s coastal influence often mirrors Somerville’s timing.
How does Somerville’s local geography affect its forecasts?
Somerville sits on the Mornington Peninsula, roughly 50 kilometres south-east of the CBD, so bay breezes and a rain-shadow effect from the Otway Ranges play a big role. The live forecast above captures those nuances.
- The closest official observation site is at Coldstream (elevation 83 m), but the peninsula’s own Weatherzone Somerville station often records higher humidity near the coast.
- Locals often check “weather Somerville Vic” for the bay’s effect on daytime temperatures – typically 1–2°C cooler than the outer northern suburbs.
- For radar, use the BOM Melbourne radar to see showers forming over the bay before they reach Somerville.
- If you need “weather in Somerville Victoria 10 days”, the 10-day outlook includes the peninsula’s coastal gradient.

Does the Somerville weather radar show rain before it arrives?
Yes. The Bureau of Meteorology’s Melbourne radar (at Laverton) covers this area well. Showers forming over Port Phillip Bay appear 30–45 minutes before they reach Somerville, so check the radar link in the sources below.
How does Somerville compare with Frankston weather?
Frankston sits closer to the bay and is often 1–2°C cooler and slightly windier in the afternoon. Somerville, being slightly inland, can see afternoon temperatures rise a bit higher before the sea breeze kicks in – the live forecast above accounts for that difference.
