Seabreeze forecast wind speed in KNOTTS and BOM in KILOMETERS. Seabreeze is more dedicated to boaties so I understand and appreciate wind speed in knotts. However, BOM is forecasting wind speeds for next few days using very similiar numbers but in kilometers which is very different. This is confusing, who is correct, BOM or Seabreeze?

Marine forecasts from BOM are in knots.
Terrestrial forecasts in Km/h.

Look at all possible forcasts and then make up your own mind. They vary heaps.
Here's some of the ones I use.

Yeh I use Meteye to confirm as well.

www.bom.gov.au/australia/meteye/

Spot forecasts out to 7 days and if you click "detail" at the bottom of the box for each day, 3 hourly predictions for your precise location.
Kmh or Kts your choice. Knots make much more sense to me.

Don't get me wrong, I reckon Seabreeze gives a brilliant instant overview, which is first class with tide and swell all there.

and weather girls obviously don't get it.

Plenty of times I have sailed maxed out on 5.0 and the evening news says it is SSW 20km. I swear they must not notice there is kn and km.

1 nautical mile is 1.852 kilometres, 1 knot is 1.852kilometres an hour.
It's also very close to 1 minute in lattitude so easy to put on charts. Also time wise,.with 60 to the hour it made calculations easier, anyhoo knots are the only way to talk wind its heritage listed ****. And depth should always be in fathoms. But I digress

^^^ I was on a 10sq cubits sail today.
Sailed out at least 5 chain to the break, got rolled by a 6ft set in only half a fathom!

5 chain is a long swim back into a force 3 breeze.

Used panties and vials of school girl drool... but the porn has all the naughty bits pixelated out except for the cartoon kiddy porn at the convenience stores...

I'm still not seeing a connection though
