Coronet Bay currently has the conditions shown in the live forecast above, typical for this time of year. The bay’s coastal position means conditions shift quickly with the tide and wind patterns from Western Port.
What is the typical weather pattern in Coronet Bay?
Coronet Bay sits on the eastern side of Western Port, about 90 minutes south-east of Melbourne. Summer days reach the mid-20s Celsius with sea breezes from the south-west. Winters are cool, with daytime highs around 14–15°C and persistent drizzle. Spring brings the windiest conditions, often affecting boaters and those checking Wonthaggi weather for a more inland comparison.
How do tides and wind affect conditions?
The tide range in Western Port exceeds two metres. Low tide exposes mudflats and can drop air temperatures by several degrees. The prevailing south-westerly wind picks up from late morning, making afternoon sailing brisk. For detailed timing, consult the Melbourne weather marine forecast and local coronet bay tides charts.
