The Lowdown
Alright, let’s get into it. The long-range charts are showing a pretty quiet stretch ahead for our stretch of coast, but there’s a window of clean, rideable surf on offer if you pick your moments. Don’t expect any hero waves, but the mornings are where it’s at.
The standout is going to be Tuesday morning, August 11th, at Udo Shrine. We’ve got a clean 4ft of east swell rolling in with a 12-second period, and the wind is dead glassy. It’s a reef setup, so that long period is going to give it some proper shape. It’s not huge, but it’ll be lined up and clean. The water’s sitting at 84°, which is about average for this time of year, so it’s not a shock to the system.
The energy is moderate at 739, so there’s a bit of push behind it. Just know this spot is inconsistent, so you gotta be there when it’s on. Crowds are often a thing here, so get out early.
After that, the surf dips out for a few days. The middle of the week is looking poor, with small, crumbly south swell and onshore breezes making a mess of things. Not worth the paddle.
The next real highlight is Sunday morning, August 16th. The east swell returns, a touch smaller at 3ft, but again, glassy conditions and a 10-second period. It’s a clean, fun-sized option. The energy is a bit weaker at 309, but it’ll be rideable. Then Monday morning, August 17th is similar, with a slightly better 4ft east swell and a longer 11-second period.
After that, things really shut down. From the 18th through the 24th, it’s mostly tiny, poor surf. There’s a small window on the 21st and 22nd with glassy mornings, but the swell is just too small to get excited about. The 25th shows a bit of life in the afternoon with 3ft east swell and a 13-second period, but it’s light and clean, more of a longboard wave.
So, in short: get on it Tuesday morning, then again Sunday and Monday. The rest is a waiting game. The swell energy stays pretty weak for the most part, so we’re not looking at any proper power. It’s not a bad run, just a quiet one. Keep the board waxed and the eyes on the horizon.

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.
