The Lowdown
G'day, I'm Rusty. Let's have a look at what's on the menu for the next couple of weeks.
Alright, I'll be straight with you – this run is a tough one. We're looking at a long stretch of flat, weak, and messy conditions, with the first real chance of anything decent not arriving until Tuesday, September 15th. That's a two-week gap of poor surf, so patience is key.
The only flicker of hope in this whole outlook is a standout day on the 15th. Rehoboth Main (Rehoboth-Main) is the place to be on Tuesday morning, September 15th. Get ready for a clean, glassy session with light cross-offshore winds from the SSW. The swell is set to be a small 5ft out of the East, with moderate wave energy at 243. It's not a monster, but with those clean conditions, it'll be the most fun we've seen in a while. The water is a touch warmer than normal at 76°, so that's a nice bonus for a quiet session.
Before that, it's a waiting game. From Monday, August 31st, right through to Monday, September 14th, we're looking at flat, lumpy, or onshore conditions. The wind is mostly a problem, and the swell is tiny with very weak energy (values like 12, 15, 29). There's a brief moment on Thursday, September 3rd, with a clean morning and a 2ft E swell, but it's still considered "very ordinary." It's a consistent spot, but it's just not on.
The big spike on September 6th has 5ft of swell, but with a strong cross-onshore wind and a short period of 6 seconds, it's a choppy mess. It's not for paddle surfing; that setup looks more interesting for kite surfing than a clean wave.
So, the call is simple: mark your calendar for Tuesday, September 15th. Dawn patrol at Rehoboth Main will be the window. The rest of the 16 days? Grab a coffee, tie some flies, and wait for the next proper swell.
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.
