The Lowdown
Alright, Rusty here.
Let’s be straight with you. For Rehoboth Main, the next week plus is a tough slog. We’ve got a whole lot of small, weak, and messy conditions stretching from Thursday the 13th all the way through to Wednesday morning the 26th. The swell is tiny, mostly under 2ft, with combined wave energy sitting in the low double digits (5 to 63) the entire time. The winds are all over the shop, often cross or onshore, and the wave comment just keeps calling it "poor surf conditions." For a beginner spot like this, it’s a flat spell. There’s nothing worth paddling out for.
The first real glimmer of hope comes on Thursday the 27th. We see a building swell from the ENE pushing 5ft by the morning, with moderate energy (167). It’s still cross-shore and messy then. But the afternoon is where it gets interesting. The wind swings around to the west, going offshore, and that swell jumps to a clean 6ft with the energy climbing to 256. That’s a proper pulse of moderate wave energy and the wave comment finally reads "expect good surf conditions." This is the standout window. For a beginner-friendly break, 6ft is pushing into the intermediate zone, but with offshore wind cleaning it right up, it’ll be fun for those with a bit of experience. Just be aware, crowds at Rehoboth Main are always present, so expect company.
Friday the 28th morning still has some 5ft surf from the E, and it’s clean with a cross-off wind, but the energy drops back to 193. It’s a solid follow-up session but not as strong as the Thursday afternoon peak.
In the end, the entire first week and a half is a write-off. You’re looking at a massive gap with nothing on offer. The only true standout to mark on your calendar is the afternoon of Thursday the 27th. It’s worth waiting for.
Rusty.
