The Lowdown

Alright, this is Rusty, and I’m looking at the forecast for Udo Shrine. It’s a reef setup that needs south in the swell window, and it’s inconsistent, so it takes a bit of patience and the right direction to fire.

Right off the bat, we’re in a bit of a dry spell. The first couple of weeks are looking pretty grim. From Sunday the 6th right through to the 16th, it’s mostly a write-off. We’ve got a lot of cross-onshore wind, choppy conditions, and the swell is just not cooperating. There’s a bit of energy out there, but the wind is trash. The combined energy gets up to 571 on the 14th, but it’s also onshore and messy, so it’s not one to get excited about. The water temp is about what you’d expect for this time of year, nothing weird going on there.

There is a little moment in the middle of the second week. On the morning of Tuesday the 15th, we’ve got a 6ft swell from the east, but it’s still a bit of a gamble with the wind and questionable tides. It’s not going to be perfect, but it’s the closest thing to a window we’ve had in a while. The period is only 9 seconds, so it’s a bit of a windswell feel, not a grunty groundswell.

The real standout, and the only one I’d circle on the calendar, is the morning of Friday the 18th. I’m talking glassy conditions, with the wind going completely still. The swell is only 3ft from the east, with an 11-second period, so it’s a long-period groundswell. That’s the kind of energy that can wrap around a reef and offer up some clean, lined-up waves. The combined energy is 180, so it’s moderate, but the glassy conditions make it a winner. The swell direction is east, but the optimum for this break is south, so it’s a bit of a compromise. Still, with that kind of glass, it’s the best we’ve got.

After that, the energy drops off fast. The 20th and 21st are back to small, weak, and messy with the usual cross-onshore wind. The combined energy dips to 56 on the 21st, which is just weak.

So, to wrap it up: the first 12 days are a wash. The 15th is a maybe for the desperate. The absolute pick of the trip is the morning of the 18th, with glassy conditions and a long-period groundswell at Udo Shrine. It’s an inconsistent break, so you need to be in the right place at the right time, but that morning could give you a few clean ones.

Rusty.

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.
