The Lowdown
Alright, Rusty here again. Let’s break it down real simple. The forecast starts with a long stretch of trash – strong cross-onshore winds, lumpy chop, and blown-out surf from August 12th all the way to the 23rd. That’s nearly two weeks of no-go. Then, right at the end, we get a few days of glassy, clean water, but the swell is small.
The first real chance to paddle out is Thursday, August 24th. At Rabbit/Manana Island, the wind goes glassy in the morning and stays light and variable through the afternoon. The swell is tiny at 0.8m to 0.9m from the east, with a period of 9 seconds. The energy is weak (101 to 143 units). The water is about average for this time of year. It’s not going to be big, but it’ll be clean. Crowds are possible, but with the small size, it’ll be mellow.
The next day, Tuesday, August 25th, keeps it clean with cross-offshore and glassy conditions. The swell sticks around 0.9m to 1.0m from the east, period 9 seconds, energy still weak (135 to 160 units). It’s a tiny, clean wave. The break is fairly consistent, so you can count on it. The best of a quiet stretch.
The rest of the forecast into late August is small and cross-shore, nothing to get excited about. The 24th and 25th are your best shots.
Rusty.
