The Lowdown
Alright, Rusty here again. Let’s put it in feet and miles per hour.
We’re looking at a quiet start, with nothing much to ride for the first few days. The water’s about 65°F, which is pretty standard for the season.
The real highlight is Sunday morning, August 2nd. We’re looking at a clean 5ft SSE swell with a long 12-second period, and the energy is solid (609). The wind is light from the NNW, keeping it glassy. That’s the session you want. The next best is Saturday afternoon, August 1st – a clean 4ft SSE swell, with a 9-second period and total glassed-off conditions. The energy is 382 (moderate wave energy). It’s a beach/sandbar setup, so don’t be surprised if it gets a bit crowded.
Later on, the morning of Saturday, August 8th, is a big one. A 7ft SE swell (10-second period) and 755 energy (moderate to strong) with a light offshore north wind. That’s a proper size, so it’s for the advanced folks. The morning of Sunday, August 9th, is also a solid option with a 6ft SE swell and clean conditions.
The second week looks a bit more uncertain with onshore wind and rain, so the Saturday and Sunday mornings (8th and 9th) are the best bets, but keep an eye on it as we get closer.
Rusty.
