The Lowdown

Alright, Rusty here, let’s have a look at what’s cooking for the next couple of weeks.

Honestly, the start of this run is a real flat spell. We’re looking at a solid week of nothing worth paddling out for. From Tuesday the 18th through to Saturday the 23rd, it’s just tiny, weak waves with poor conditions. The energy is barely there, and the wind is mostly messy. You’re better off taking the week off or doing some maintenance on your board.

The first real glimmer shows up on Sunday the 23rd afternoon. We’ve got a tiny 3ft swell from the SSE, but the wind goes light and clean. It’s surfable, but very ordinary. That little trend continues into Monday the 24th with a glassy afternoon session – 2ft, SSE, clean and glassy. The energy is still weak (44), but for a summer knee-high dribbler, it’s as good as it gets.

Then we hit a rough patch again mid-week. The wind picks up and the swell stays small and junky. Nothing exciting until Thursday the 27th afternoon, when the energy jumps to 314 and a 5ft S swell shows up. The wind is cross-off and clean, but the period is short at 7 seconds, so it’ll be a bit soft and lumpy. Still, it’s the biggest wave we’ve seen.

The real standout is Monday the 31st of August. The morning session at Rehoboth Main looks like the best on offer. We’re looking at a solid 6ft swell from the E, with a clean, light breeze and glassy conditions. The wind is cross-off, so it should be clean. The energy is strong at 306. This is a proper summer swell. The only catch is the afternoon – the wind swings onshore and gets choppy, so get out early.

The period is short at 6 seconds, so it might be a bit soft and fat, but for a beach break, it’s got some push. The water temp is about average for this time of year, so a spring suit is fine.

After that, it drops back to small and mediocre for the first couple of days of September. Tuesday the 1st and Wednesday the 2nd are back to tiny, poor conditions.

So, the pick of the run is the morning of Monday the 31st of August. It’s the biggest, cleanest swell we see. The rest of the window is mostly flat or very small. If you’re desperate, Sunday the 23rd afternoon and Monday the 24th afternoon offer tiny, clean waves for a longboard. For the rest, it’s a waiting game.

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.
