Check the live forecast above before heading out, as Frankston North’s coastal position means sea breezes can drop temperatures sharply in the afternoon, even when the morning is mild.
What makes Frankston North’s weather different from inland Melbourne?
Frankston North sits on the eastern edge of Port Phillip Bay, so it often stays a few degrees cooler than central Melbourne in summer and less frosty in winter.
- Afternoon sea breezes arrive from the south-west, pulling cooler air off the water from late morning onward
- Summer maximums can be 3–5°C lower than the city when a northerly wind is blowing inland
- Winter minimums are milder due to the bay’s thermal effect, usually 1–2°C warmer than outer suburbs
- Rainfall is spread fairly evenly year-round, with spring the wettest season on average
Will the weather in Frankston tomorrow be different from today?
Not usually, unless a change is forecast. Check the live forecast above for the next 24 hours.
- A south-easterly wind change can bring cloud and drizzle, especially overnight
- Clear skies and a northerly wind mean warmer conditions ahead of a cold front

How reliable are the weather in Frankston 10 days forecasts?
Day 5–7 forecasts give a useful trend but can shift by 2–3°C or more by the day. The 10-day outlook is best used for planning, not firm decisions.
- BOM Frankston weather data is the most reliable source for official warnings and observations

What causes the sudden temperature drop in Frankston North on summer afternoons?
The sea breeze from Port Phillip Bay arrives between midday and 2pm, pushing cooler marine air inland. Temperatures can fall 6–10°C in under an hour. The drop is more dramatic on days with a hot northerly wind in the morning.
Does Frankston North get frost in winter?
Occasionally, but less often than inland suburbs. The bay’s warmth raises overnight minimums, so frost is mainly confined to clear, calm mornings after a dry spell. Light frost may occur once or twice a season near open ground.
Where can I check live BOM Frankston radar for rain?
