Two days so far, gentle SE all day and a little SSW seabreeze coming in about 3pm.

We may be on soon! Anyone up north have anything yet?

Optimistic I know .... don't spoil it for me boys.

had the good fortune to be in Lancelin yesterday, after surfing glassy waves all morning, 20 knot southerly arrived (from where?) and lasted 2 hours, solid swell, fully powered on 5.7, probably could've rigged the 5.3. on my own except for a couple of kiters. Sunny, and super clean waves, sure the wind just stopped and I had to swim the last 300m back to the beach but it was worth it.

Hmmm...not sure that a NWer into a SWer constitutes a seabreeze, but I admire your positiveattitudalness

This was found in the Help section under The Wind

Seabreezes...

Cold sinks, heat rises. It's the concept that makes hot air balloons work, and why your vegies are at the bottom of the fridge. During a summer day, the land is heated by the sun, and this heat is absorbed by the surrounding air. Once this air meets a particular temperature, it begins to rise quite rapidly. As a result, a low pressure area is created at ground level. The sea doesn't heat up as quickly as the land, so the air temperature over the water is much less. As a result, this air is free to move sideways to occupy our new low pressure area. The result is a light to gale force wind which rushes in from the sea to fill the lower pressure area left by the hot air rising from the land. Seabreezes usually happen in spring and summer, when the difference in temperature between land and sea is greatest.

Seabreezes are the most amazing phenonenom. For many years I never really paid much attention to the wind. One day, we arrived (late) at the local river to do some water skiing. It was around 1pm, the water was glassy - perfect conditions. Then, me mate Mick says "Here comes the seabreeze...". Looking across the river we could see an approaching line of rough water. And then it hit us full on - the full glory of a 25 knot seabreeze.

What's even more amazing is that the wind can be travelling faster than the front of the seabreeze. It can be progressing inland at 25 km/h, but the actual wind can be blowing at 35 km/h! Sometimes the seabreeze can reach many kilometers inland, and other days it teases you by staying just offshore, coming in, and then going out again.

So to get a seabreeze, it needs to be hot inland. But too hot and you won't get one at all. To explain why this is the case, we need to understand high's and low's and the squiqqly charts they show on the telly called 'Synoptic Charts'.

Yep lads, pretty sure it was a seabreeze at Rotto on Monday earlier this week............ Apparently the surface ocean temp is quite low at the moment.
