Somebody wise once said Seabreeze for Northerlies and BOM for Southerlies. I tend to agree.
i am pretty sure they all get the info after watching the 6pm news.............and then go to the pub and have a laugh at all the windsurfers, kites, charter boats doing nothing.
silly queenslanders forget to put tassie on the map, and now south straddie
question is, which BOM - arrows or text?
does wind come off a low at 45 degrees-ish like it does with a high? maybe it really will have some east in it?
That wind map is completely at odds with the forecast for Moreton Bay - at least strength-wise.
Moreton Bay Waters:
Friday until midnight: Wind: W/SW 15/20 knots. Sea: 1 metre.
Saturday: Wind: W/SW 15/20 knots. Lighter winds inshore early. Sea: 1 metre.
Sunday: Wind: SW 15/20 knots.
Monday: Wind: SW/SE 15/25 knots
the wind maps on the bom site are computer models without human intervention.
the written forecast is the human version after looking at the models.
bom uses ecmwf models up until 2 days out and then uses it's own models. that's why sometimes you can get a big change 48 hours to go.
with the land models foreast wind maps it switches 24 hours out.

i think the changing direction is the influence of the land heating up. so a southerly will kick SSE-SE as the day progresses and a northerly with kick NE etc.
ok ............lets go to maui they say 15knts and its 25/30knts.....like their system
