The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s cookin’.

Straight up, the next 16 days are a real struggle for surf. We’ve got a long dry spell kickin’ things off. From the first recommendation on Wednesday, August 26th, right through to the end of the first week of September, it’s mostly flat, weak, and messy. The wave energy is just sad, with combined energy values barely crackin’ 100 (like 15 to 112) for over a week. The whole window is a test of patience. There’s a small pulse of energy around the 4th of September, but it’s plagued by poor wind and short-period chop.

Alright, so where do we even start? The only spot in the game is Rehoboth Main. First up, on Wednesday morning August 26th, it’s glassy with a mere 0.7ft of swell from the ESE, period a tiny 10 seconds. Energy is a pathetic 15. It’s not surfable, just a flat, glassy pond. The water temp is about average for the time of year, so no surprises there.

The rest of that week is a write-off. Thursday and Friday see a little more swell (1ft), but the wind is cross or onshore, and the wave comment is “poor surf conditions.” Energy stays in the 20s and 30s. Not worth paddling out for.

The weekend of the 29th and 30th is the same story – tiny swell, cross-on winds, and energy levels dropping to 30 or less. It’s a beach break, so with this weak, short-period stuff, it’s just washing machine conditions.

We get a brief moment early in the second week. On Tuesday, September 1st, the swell is only 0.7ft, but the period jumps to 15 seconds – a very long period groundswell. The energy is 34. It’s glassy in the morning. This is a tease. That long period will just make those tiny waves fat and straight at a beach break. Not really a goer.

Then on Wednesday, September 2nd, we get a slight bump. The morning has 1ft of swell from the SE, period 12 seconds, and cross-offshore wind from the WNW. The energy is 58, and the wave comment is “surfable waves but very ordinary conditions.” It’s the best of a bad lot, but honestly, it’s still a weak, average day.

The only real bump in the whole 16 days shows up around Thursday, September 3rd, and Friday, September 4th. The swell height hits 3ft to 4ft, direction shifts to ENE, and the period is a short 5-7 seconds. The combined energy finally climbs into the low hundreds (112 to 125), but the wind is all wrong – cross-shore or cross-onshore. This is a short-period, choppy, wind-affected mess. At 4ft, it’s a bit much for beginners, but the quality is so poor it’s not really a winner for anyone. With that onshore wind and small period, this setup at a beach break looks more interesting for a kite surfer than a paddle surfer.

After that, it fades back to nothing. By Monday, September 7th, we’re back to 2ft with poor cross-shore wind. The rest of the forecast is a flat, weak end to the run.

There is no standout period. No day to circle on the calendar. The run from August 26th to September 10th is mostly a blank, with only a few fleeting, average moments. It’s a tough stretch for the area, but it’s one of those runs where the forecasts can change, so keep an eye out.

Rusty.

Information about the Rehoboth Main Surf forecast

The above surf forecast table for Rehoboth Main provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Rehoboth Main can be found by selecting the local surf guide option on the grey menu. Our Rehoboth Main surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Rehoboth Main) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. 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. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
