The Lowdown
Alright, listen up. Rusty here. I'm gonna be real with you – the next week and a half at Udo Shrine is a total loss. Forget it. The ocean is going to be a mess of storm energy and howling winds. We're looking at a long stretch of nothing but blown-out, lumpy surf.
The water is a warm 85°, which is pretty standard for this time of year, but that’s about all that’s normal.
That first big pulse of swell hits on the 5th and 6th of August, but it's way too big and the wind will be straight onshore. The whole place will be a washing machine. We're talking about a lot of water moving, but it's all just whitewater. That run of bad conditions is going to stretch all the way through the middle of the month.
So, what are we waiting for? Look at Monday, August 17th. The wind is finally supposed to turn offshore. The swell backs down to a manageable 10ft from the East with a 11-second period. East is the right direction for this break, and with clean conditions, it could actually be fun. The energy is moderate, but the clean face will make it worthwhile. That's our first real hope, but it's a week and a half away, so don't book your flights yet.
And then, the one to really get excited about – Tuesday, August 18th. The swell is still a solid 8ft from the East, but the wind is forecast to be dead calm. Glassy. That's the day. The reef should be working perfectly. But remember, this place is inconsistent, and at that size, it's only for experienced surfers.
Bottom line: be patient. Sit on the beach for a week, then be ready to paddle out when that clean window arrives around the 17th and 18th. It might be a wait, but it could be worth it.
Rusty, signing off.

A general guide to surfing at Udo Shrine can be found by selecting the local surf guide option on the grey menu.

Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Udo Shrine may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself.
