The Lowdown
Hey folks, Rusty here. Let’s talk about what’s happening around Rabbit/Manana Island. To be honest, this 16-day forecast is a tough one. We’ve got a solid stretch of wind that’s just going to wreck any decent swell that comes through.
The water temperature is about what you’d expect for this season, so nothing unusual to report there.
Starting from Sunday, August 2nd, and running all the way through Saturday, August 16th, it’s just a long list of “poor surf conditions.” The wind is relentless from the ENE, blowing 19 to 25 mph, making the water a messy, lumpy chop. The swell hangs around mostly short period (7 to 8 seconds), and while the height fluctuates from 3ft to 7ft, the wind is just too strong to let anything clean up. The combined swell energy is mostly moderate, hitting around 913 early on, but it’s all energy you can’t use.
The only day that might be worth a look is the very last one. On Monday, August 17th, we get a “marginal surf forecast” with a tick up to a score of 1 out of 10. The swell is up to 7ft from the ENE with a 7-second period, but the wind finally drops to a moderate cross-shore at 12 mph. The combined energy is 525, still moderate. For an intermediate surfer, you might catch a few lumpy ones. But it’s still not clean. The optimum swell direction for this break is NNE, so this ENE swell is off-angle. With that size and the onshore/cross conditions, this beach-and-reef setup might actually be better for a kite surfer than a paddle surfer.
All in all, there are no great days to highlight. It’s a tough two weeks. Just keep an eye on the forecasts, because it never stays bad forever.
Rusty.
