The Lowdown
G’day, Rusty here. Let’s be straight with you – for the next couple of weeks, Rehoboth Main is a tough ticket. There’s a long, long gap of flat or next-to-nothing conditions to start, and even when the ocean finally stirs, it’s messy. The first real pulse of energy doesn’t show up until the middle of the second week, and even then, the wind isn’t playing nice. Let’s walk through it.
The first week is a write-off. From Saturday the 5th right through to Tuesday the 15th, we’re looking at tiny swell – mostly 0.7ft to 3ft – with periods that are short and weak. Combined wave energy barely breaks 50 for most of that time, and the highest we see is a measly 54 on the afternoon of Tuesday the 15th. That’s weak, flabby surf. Winds are all over the shop – cross, cross-on, cross-off, onshore – but it doesn’t matter much because there’s nothing to ride. The only moment that even hints at potential is Monday afternoon the 7th: glassy conditions with a calm wind and a 10-second period swell from the E at 2ft. But even then, the energy is tiny (50), and it’s a one-off that doesn’t last. For a break that’s always crowded and exposed, this stretch is a dead loss.
Then, finally, a change arrives. From Wednesday morning the 16th, the swell starts to build. Wednesday morning sees 5ft from the E at 6 seconds, but it’s onshore and choppy – combined energy of 153 (moderate). That afternoon jumps to 5ft at 7 seconds, energy 257, but again it’s cross-onshore and choppy. Not clean, not inviting.
The standout window – and I mean the only window worth talking about – is Thursday the 17th through Friday the 18th. On Thursday morning, we get 5ft from the E at an 8-second period, with a light cross-shore breeze and only a slight cross-chop. The combined swell energy hits 323, which is solid moderate energy. It’s not perfect, but it’s the best on offer. That afternoon the wind picks up to a moderate cross-onshore, making it choppy again, but the morning session holds promise. Then Friday morning the 18th keeps it going: 5ft from the E at 9 seconds, with light cross-shore wind and small wind ripples, energy at 375. That’s the pick of the whole forecast. The sets will have some push, and the period is decent enough for a beach break – though a 9-second period isn’t long enough for the super-straight lines that can be tricky here. It’s exposed and the crowd will be there as always (this place is never empty), but if you get in early Thursday or Friday morning, you might snag a clean one.
After Friday, the swell drops back. Saturday the 19th fades to 3ft and then 3ft, still onshore, and by Sunday the 20th it’s back to 2ft and 1ft with moderate onshore wind. The window closes.
So here’s the summary: the first two weeks are mostly a bust. You’re waiting until the 17th of September for anything rideable. Thursday morning the 17th and Friday morning the 18th are the best shots – expect 5-5ft E swell with light winds, but know that crowds are inevitable at Rehoboth Main, and the conditions are only marginal, not epic. The water is much warmer than normal for this time of year, sitting at 77°F with a +5°F anomaly – that’s notable, so you can leave the thick wetsuit at home.
Stay stoked, but be patient.

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.
