The Lowdown

Alright, grab a coffee and settle in, because I gotta be straight with you – the next couple of weeks are looking pretty grim for a paddle. Let's get into it.

So, we're looking at Rehoboth Main. Right off the bat, the water is sitting at 78°, which is a touch warmer than normal for this time of year. Feels nice, but the waves are the problem. We’ve got a run of tiny, weak swell for the first week and a half. We’re talking about a knee-high dribble from the 18th of August right through to the 30th. The combined energy is mostly in the single digits or low teens, which is just flat-out weak. There’s a few days where the wind is clean – like Wednesday the 19th with a light cross-off, and even a glassy morning on the 25th – but the waves are just too small to get excited about. It’s a long, dry spell.

The first real glimmer of hope doesn't come until the 30th of August. Sunday morning, the wind is a light cross-off from the NW, and we finally see a bit of swell, about 2ft from the ESE. The period is 9 seconds, so it’s got a little bit of shape to it. The energy is up to 71, which is still pretty weak, but it’s the best we’ve seen. The conditions are described as "surfable but very ordinary," which is about right. This is the only window that’s truly worth a look. The wind stays clean into the afternoon, but the swell is tiny.

The next day, the 31st, the wind goes cross-shore and the energy drops back down. Things just get messy again. The wind is onshore or cross-onshore for most of the first week of September, with that weak SE swell barely making a ripple. The energy occasionally climbs into the high 70s or 90s, but with short period waves and dirty wind, it’s a no-go. The setup is a beach break, and with the wind howling onshore for most of it, it’s looking more like a kite-surfing window than a paddle-surfing one.

In short, there’s only one time to even think about getting wet: the morning of Sunday the 30th of August. It’s not a standout, it’s just the only option. Beyond that, it’s a long wait for anything decent.

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.
