Table - best surf conditions forecast for Udo Shrine over the next 16 days.
Alright, let me look at what we’ve got coming up for the next couple of weeks. It’s a bit of a mixed bag, but we’ve got some serious size on the way.
First up, we’re looking at a real beast of a setup. The swell energy is absolutely pumping, with a combined energy of 5103 – that’s some serious power in the water. We’re talking about a solid 9.8ft groundswell from the SE, with a super long 15-second period. The water’s sitting at 78.6°, which is a solid 3.1° colder than usual for this time of year, so you’ll feel that chill.
Thursday morning (July 9th) kicks things off at Udo Shrine, a reef break that’s really exposed to the south swell. The wind is onshore from the ENE at 9 mph, which is a bit of a bummer because it’ll mess with the surface. The reports say it’s marginal, and the tide might be a factor too. This is a big, powerful wave, and at 9.8ft, it’s already in the "experts only" territory. It’s over 8.2ft, so if you’re not on your A-game, sit this one out. The crowd situation is "often" here, so expect a few people jockeying for position.
Moving into Friday, July 10th, the swell jacks up even more. Morning sees 13.1ft waves from the SSE, with a 16-second period and a combined energy of 8439 – that’s a proper ocean roar. The wind is still cross-onshore from the east at 12 mph, which is going to make it choppy and messy. By the afternoon, the swell hits 14.8ft, period stretches to 17 seconds, and the energy goes through the roof at 10514. This is massive, powerful, and dangerous. Only for the most experienced, and even then, the cross-onshore wind is going to make it a battle.
Saturday, July 11th, is a write-off. The morning is a no-go with 13.1ft swell, strong cross-onshore wind at 16 mph, and a storm risk. The forecast literally says "poor surf conditions" with a score of zero. Save your energy.
Things start to ease down on Sunday, July 12th. The swell drops to 8.2ft, period shortens to 13 seconds, and the energy is down to 2235. The wind is a light cross-onshore breeze from the SE, so there’s some ripple on the surface. It’s still big and a bit unruly, but the window is starting to close on the massive stuff.
Monday, July 13th, is our first real highlight. The swell has dropped to a much more manageable 5.6ft, still from the south with a 11-second period. The energy is down to 726. The wind, however, is a game-changer. It’s a light cross-offshore breeze from the SSW at 6 mph. The morning is described as "expect very good surf conditions" and it’s clean. This is the sweet spot. The waves have shape and power, but the wind is keeping the face smooth. This is the best bet for the first week if you want quality over sheer size.
Tuesday, July 14th, is another good one. The swell is 3.3ft from the south, with a 10-second period. The energy is low at 246. But the wind is glassy. Dead flat from the WNW, glassing off the surface perfectly. The morning is clear and glassy. This is a fun, clean, small day. Not going to get barreled, but perfect for a longboard.
From Wednesday, July 15th, through to the 19th, it goes flat. The swell drops below 3.3ft, the energy is pathetic, and the wind is all over the place. It’s a full 5-day gap of nothing worth paddling out for. The calls are for "surfable but very ordinary" or "poor" conditions. A real lull in the action.
Then, a big change. Around Monday, July 20th, there’s a pulse of new swell. The swell is 7.2ft from the east, but the period is a terrible 7 seconds – that’s windswell, not groundswell. It’s going to be weak and choppy. The energy is 645.
But hold onto your board. Tuesday, July 21st, the real second-standout arrives. The
