The Lowdown
Alright folks, Rusty here. Let’s be straight with you. I’ve looked over the next couple of weeks for our stretch of coast, and I’ve got to be honest – it’s a tough watch. We’ve got a long, flat spell ahead with very little to get excited about. The swell is just not showing up, and we’re going to be clinging to scraps for most of the period.
The water’s sitting at 78°, which is a touch warmer than usual for this time of year – not a bad thing when you’re just floating around waiting for a ripple.
We start off with a few days of tiny, short-period slop. Sunday the 9th has a small 2ft south swell with a 5-second period, and the energy is weak, just 28. The wind is a cross-off but the waves are just too small and weak to be worth a paddle. Monday and Tuesday are even smaller, with nothing breaking properly. We’re checking weak energy readings in the low teens and single digits, just to give you an idea. It’s flat, mates.
There’s a slight bump Wednesday afternoon with a bit of an offshore wind and clean conditions, but the swell is still only 1ft. It’s ankle-biters at best. The wind picks up a touch on Thursday, but the swell stays pitiful.
The first weekend brings a little more wind, but the surf remains poor. Sunday the 16th sees the wind really howling from the south at 22 mph, with a lumpy 4ft of short-period windswell. It’s a messy, onshore mess. Honestly, with that wind and the junky surf, this looks more like a kiteboarding session than a surf – at least they’d be having fun.
After that, the pulse dies again. We’re looking at a stretch of days with pretty much nothing – just tiny, weak waves and not a single decent option on the horizon.
Now, for a couple of brief glimmers. Around Wednesday the 19th and Thursday the 20th, we see a slightly longer period swell trying to push in from the southeast. The energy climbs a bit, up to 95, but the wave height is still only around 2ft. The wind is offshore on Wednesday afternoon, and it’ll be clean, but it’s still just not enough to get your heart racing. It’s the type of day where you make do with what you’ve got, but it's a marginal call at best.
Otherwise, the rest of the window into the following week just fizzles out. There are long gaps of several days with no recommendations, just periods of flat, calm water. We’re looking at a pretty blank run, which does happen here. The long-range stuff, like around the 23rd and 24th, is just more of the same, with tiny swells barely registering.
So, keep the board in the car, but maybe focus on something else for a while. It’s a tough stretch. I wouldn't hold your breath for any standouts – there just aren't any. Forecasts can change, but right now, this doesn't look good.
Rusty, signing off.

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.
