Table - best surf conditions forecast for Udo Shrine over the next 16 days.
Right, let’s have a look at Udo Shrine. It’s a reef break that’s inconsistent and can get crowded often, but when it fires, it’s a special little wave. The water’s sitting at 79°, which is a bit colder than normal for this time of year – nothing wild, but you’ll feel the difference. The whole period kicks off with a solid pulse of southerly groundswell, but the wind is messy and onshore, so the surface will be choppy and tough to love.
The best of the early window is Thursday, July 10th. We’ve got a big SSE swell running, around 13 ft in the morning and pushing 15 ft in the afternoon, with a long 17-second period. The combined energy is pumping hard (10297 in the morning, 11117 in the afternoon). That’s serious power. The trouble is the wind is onshore at 12 mph from the east, and there’s a risk of thunderstorms, so it won’t be perfect. The break is exposed to the south and the optimum swell direction is from the south, so the direction is a solid match for what’s coming. This is only for experienced surfers – the size and energy are too much for beginners. Look for early morning lulls if you can, but the wind will be a battle.
After that, the swell drops steadily through the weekend and into the following week. By Sunday, July 13th, it’s down to 5 ft with a cross-shore breeze, and the energy is weak (558). Conditions are ordinary. The next solid window shows up on Sunday, July 19th, with another east swell building to 10 ft in the morning and a 9-second period. The combined energy jumps back up to 1517. The wind is light and cross-onshore, which at least keeps the surface from getting too messy, but the direction is east, and the optimum swell direction for Udo Shrine is south. That mismatch means the waves won’t be as lined up as they could be. Still, it’s a big swell and the cleanest option in the second week for those who don’t mind a bit of cross-shore chop.
Monday, July 20th, holds at around 8 ft with a 10-second period and moderate energy (1332), but the wind is onshore again. After that, the swell fades out into small, weak leftovers. The last day worth mentioning is Thursday, July 23rd, with just 3 ft and a 10-second period, but the wind goes glassy offshore from the east-northeast. That will make the surface perfect, but it’s a small wave. For a dedicated session, the standout is definitely Thursday, July 10th – get out there if you’ve got the experience. For the second week, Sunday, July 19th is the most promising, but keep your expectations in check given the direction mismatch.

Information about the Udo Shrine Surf forecast

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. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
