The Lowdown
Alright folks, Rusty here. Let's have a look at the next couple of weeks at Udo Shrine. It's a reef break, and it's pretty inconsistent around here, so we've got to be honest about what's on the table.
Right off the bat, we're starting with a real flat spell. The first solid week is pretty much a write-off if you're looking for anything decent. From Wednesday the 15th right through to the 26th, the energy is just not there. We're talking tiny waves, mostly under 2ft, and the wind's all over the shop. There's a few glassy moments, like Friday morning the 17th and Sunday the 19th, but the swell is just too small and short-period to really get into. The combined energy is weak, barely cracking 100 (66-127), so it's a lot of paddling for very little reward. It's a tough run for a while.
Now, things start to look a bit more promising as we head into the last few days of the month. Monday the 27th sees a jump in period, with a 15-second groundswell pushing in from the ESE. The combined energy is moderate (157-250) and the morning is glassy calm. However, the swell direction is a bit off, and the waves are still small (1ft to 2ft). It's a marginal call, but it's the best we've seen in over a week.
The real standout, and the only one I'd really get excited about, is Thursday the 30th of July. We've got a solid 6ft to 6ft SSE swell, with a very long 15-16 second period. The combined energy is strong, hitting 1474. That's proper groundswell energy. The downside is the wind is onshore and cross-onshore, which will mess up the surface. Because it's a reef break, the long period will help it handle the swell better than a beach break, but it’s going to be a bit of a battle. This is for the experts only, as anything over 5ft can get heavy, and the onshore wind will make it tricky. The rest of the second week keeps the same swell direction, but with smaller waves and cross-onshore winds, so it’s not worth getting too worked up about besides that one day.
Keep your eyes on the 30th, but don't hold your breath. The water sits at 82°F, which is pretty much normal for this time of year.
Rusty.
