It always amazes me the difference in seabreeze forecasts and those from the BoM. Why is it so?

Sunday until midnight: Wind: SE/E 15/20 knots increasing to 20/25 knots
overnight, reaching 25/30 knots south of Cape Moreton. Sea: From 1.7 to 2.2
metres, reaching 3 metres south of Cape Moreton at night. Swell: E'ly 2 to 2.5
metres. Occasional showers.

i think the bom forecasts are issued for coastal waters up to 60 knots offshore. maybe the seabreeze ones are intended for more inshore areas?

Nope....BoM forecast is for South East Coastal areas. The places where we kite.
No satisfactory explanations as yet....

Methinks BoM has human scientists, data and computer models to predict with and seabreeze is just computer models.

The next few days will tell who is right.

under the marine forecast heading: "Coastal waters forecasts are for areas within 60 nautical miles of the coast"


The coast where we kite is within 60 nautical miles of the coast! and seabreeze forecast is also for the coast where we kite.

The other marine waters forecasts are for offshore waters!!

dave i don't think you get it so let me simplify it for you- up to 60nM from the coast means from where the water starts to 60 nautical miles out to sea. high seas forecasts cover the areas past that.
coastal waters forecast is not for inshore waters only (where we kite), its meant to cover all possibilities for conditions up to 60 knots out. once you get a few miles off the coast the weather can get very different.

It's obvious! One of the moderators is planning on going out at the sunshine coast early this week and doesn't want to be disturbed.

Here is the marine wind forecast. As you can see SFA on ther beach, 325kts a little way out to sea. Time to get a boat.

I'm still confused... If the forecast is up to 60 n miles out to sea does that
mean I have to wear a pfd or not ?
