Hello Friends,
The NE wind is chewing up a metre-ish south swell this morning. Maybe tomorrow morning…
BoM Forecast issued at 4:10 am EST on Tuesday 30 September 2025.
Weather Situation
Fresh onshore northeasterly winds are forecast today ahead of a series of strong cold fronts that looks set to cross the state from today onwards. The first front will cross the coastal waters later tonight and Wednesday with a brief southwesterly wind change. This will be followed by the second front on Thursday and early Friday bringing a fresh to strong west to southwesterly wind change in its wake. Winds will gradually ease through the weekend as a large high pressure system drifts across the state.
