The Lowdown

Alright, folks, Rusty here. It’s a quiet stretch ahead for Rehoboth Main. The water temp is sitting at 76°, which is about average for this time of year, so no surprises there.

The bad news first: for the next week and a half or so, we’re looking at a real flat spell. From Wednesday the 19th all the way through to Thursday the 27th, the surf is basically non-existent with tiny waves and poor conditions. There’s a long gap there with no real recommendations. You’ll see a few glassy moments on the 22nd and 23rd, but the swell is just too small to bother with.

Things start to stir a little on Friday the 28th. The morning brings a 1ft swell from the SE, with a period of 9 seconds and a gentle offshore wind from the W at 9 mph. It’s only surfable, nothing special, and the combined energy is weak (60). The afternoon stays similar with a bit more wind at 12 mph, but still offshore – it’s clean, just small. Saturday the 29th and Sunday the 30th mornings offer the same story: 2ft SE swell, light winds, clean conditions. The best of it might be Saturday afternoon with glassy conditions and a 2ft SE swell, combined energy a weak 49. Still, these are really just ankle-biters, fine for a beginner to get wet but nothing to get excited about.

The standout window, and it’s a long-range one, lands on Tuesday the 1st of September. That afternoon we’ve got a 2ft swell from the ESE, period 8 seconds, with a gentle offshore wind from the W at 9 mph. The combined energy jumps to a moderate 147 – the strongest of the whole outlook. This is the best on offer, but it’s still ordinary waves. Wednesday the 2nd holds some clean 2ft ESE swell with a longer period of 11 seconds, but the energy drops back to weak (92). After that, Thursday the 3rd gets messy again with onshore winds.

So, overall, if you’re a beginner or just need to get in the water, the end of the month and the 1st of September are your best bet. For anyone else, it’s a waiting game. Keep an eye on the longer-range forecast, but right now, it’s pretty flat.

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.

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.
