Rehoboth Main Surf Forecast and Surf Report

G’day, I’m Rusty. Let’s get into it.

We’ve got a long, quiet stretch ahead for Rehoboth Main. The water’s sitting at a warm 76.8°F, which is 4.1°F above normal for this time of year, so it’s notably warmer than you’d expect – a real treat for the skin.

The first recommendation kicks off on Thursday, September 3rd, with weak, tiny 1.3ft SE swell pushing in at 9 seconds. The combined energy is a measly 39, so barely a bump. Wind is cross-off from the WSW at 9 mph, so the surface is clean, but there’s just not enough push to get excited about. It’s poor surf, really. Thursday afternoon is similar with a lighter offshore wind, but still 1.3ft and 38 energy – a beginner’s dribble at best.

Friday, September 4th, we’re on the same tiny swell, 1.3ft from the SE, and the period drops to 8 seconds. The combined energy falls to 28. Morning wind is cross-off from the NW at 9 mph, so it’s clean but gutless. Friday afternoon is even weaker at 1.0ft and 20 energy.

Saturday the 5th is a write-off with 1.0ft SSE swell, short period at 6 seconds, and a cross-shore wind from the N at 12 mph creating a cross-chop. Energy is just 23. Not worth a paddle.

Sunday the 6th brings a slight increase in swell height – 1.6ft from the ENE in the morning, but the period is a terrible 3 seconds, and the combined energy is only 8. The wind is cross-on from the NE at 16 mph, making it choppy. Sunday afternoon sees a jump to 3.6ft from the ENE with a 5-second period and 78 energy, but it’s onshore wind from the ENE at 16 mph, so it’s messy and poor.

Monday the 7th is the first real flicker of hope. The morning is still poor with 2.0ft E swell, 7 seconds, and 63 energy, in a cross-shore breeze. But Monday afternoon – that’s the standout. We get glassy conditions with an easterly wind at just 3 mph, and the swell is 2.0ft from the E with a period of 11 seconds. The combined energy climbs to 83, and it’s described as surfable but very ordinary. For this stretch, that’s the best on offer. It’s a small, clean, long-period groundswell, perfect for a beginner looking for gentle, clean waves. The break is exposed, so it’ll catch that SE swell, and with the glassy surface, it’ll be a rare treat. Crowds are always here, so expect company.

From Tuesday the 8th onward, it’s a bleak run. Tuesday morning has 1.3ft E swell with a 10-second period and 34 energy, and offshore wind from the W at 6 mph, but it’s still poor. The next few days are all tiny, weak, and often choppy. Wednesday the 9th has a 0.7ft E swell in the morning, energy at 10, and a cross-shore chop. The afternoon brings a 2.0ft S swell with a 5-second period, but it’s clean under cross-off wind.

Thursday the 10th offers a 2.0ft S swell at 6 seconds, with a moderate offshore wind from the W at 12 mph, making it clean. Combined energy is 37, still poor. Friday the 11th and Saturday the 12th are dominated by weak, short-period swells with onshore or cross-on winds, choppy and poor. Saturday afternoon does see 4.3ft from the E at 5 seconds with 97 energy, but it’s cross-on from the SSE at 12 mph, so it’s a messy, choppy mess.

Sunday the 13th has 3.3ft to 3.6ft ESE swell, 6-second period, and energy creeping up to 116 in the afternoon – that’s moderate energy. But the wind is cross-shore from the S at 16 mph, creating a cross-chop, so it’s poor.

Monday the 14th afternoon is another small notch: 2.0ft E swell at 7 seconds, 63 energy, clean under cross-off SSW wind at 9 mph. It’s surfable but very ordinary. That’s the second best of the whole run.

After that, from Tuesday the 15th through to Friday the 18th, it’s all tiny, weak, and mostly onshore or cross-onshore. The swell never breaks 3.0ft, periods are short, and energy is in the teens to low 80s. There’s nothing to get excited about.

So, the honest truth: this is a lean 16 days. The only two windows that are surfable are Monday afternoon, September 7th (the standout for its glassy conditions and 11-second period), and Monday afternoon, September 14th (clean but tiny). Both are beginner-sized, clean, and small. For the rest, you’re looking at a lot of flat, choppy, or weak
