What does the live forecast mean for Seaforth?
The numbers in the live forecast above give you the immediate temperature range and wind speed. In plain English, a south-easterly flow often brings cooler, moist air off the ocean, keeping Seaforth a few degrees cooler than inland Sydney suburbs. Check the “feels-like” reading to gauge how the breeze will affect your comfort on the beach or foreshore.

FAQ
Where can I check the BOM Seaforth observations?
The Bureau of Meteorology’s nearest automatic station is at Sydney Airport, about 20 km south. For coastal wind and swell, use the BOM’s Manly Hydraulics Lab buoy data; BOM Seaforth radar is not available – use the Sydney radar instead.
What are the Seaforth tide times today?
Seaforth tide times follow the Sydney Heads pattern. High and low tides occur roughly 10–15 minutes earlier than at Sydney Harbour’s entrance. Check a dedicated marine app or website for precise seaforth tide times before heading to the water.
Is the Seaforth 14 day forecast reliable?
A seaforth weather 14 day forecast gives a useful trend but confidence drops after day 7. For planning, combine the longer-range outlook with the seaforth weather hourly forecast from the live panel above, which is updated more frequently.
