The Lowdown
Hey, Rusty here. Let’s be real — Rehoboth Main is looking pretty flat for the next couple weeks. The first seven days are a total bust. Swell heights barely touch 3 ft, with weak, short-period windswell and combined energy readings in the double digits (63 or less). Winds are mostly cross or onshore, so the water’s choppy and messy. Wednesday the 15th afternoon goes glassy, but with only 0.7 ft, you’re better off swimming.
That long gap finally breaks on Monday the 20th morning. A pulse of 6 ft swell from the ENE shows up, with a combined energy of 290 — moderate. But the period is only 6 seconds, so it’s weak, junky windswell. Light cross-shore wind keeps it marginal. The afternoon stays around 6 ft but turns onshore — messy. Tuesday the 21st drops to 5 ft, still cross-onshore and choppy. Not worth it.
The rest of the second week stays small. Wednesday the 22nd through Friday the 24th see swell under 3 ft, with onshore or cross-onshore winds. Energy is weak, mostly in the 50-110 range. Saturday the 25th and Sunday the 26th bring a little more push — up to 4 ft from the south, with energy climbing to 208 on Sunday morning — but the wind is strong and gusty from the south, making it lumpy. Monday the 27th is the cleanest window: 3 ft in the morning with light offshore W wind, glassy in the afternoon. Waves are surfable but very ordinary. Tuesday the 28th is back to choppy.
No standout sessions here. If you’re itching, Monday the 20th morning has the most size, but it’s not clean. Monday the 27th is the cleanest, but tiny. For a break that’s usually fairly consistent, this is a rare dry spell. Forecasts can change, but right now, I’d stay home.
Rusty.

Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Rehoboth Main may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself.
