The Lowdown

G’day, I’m Rusty. Let’s get stuck into the outlook for Rehoboth Main.

Alright, I’m going to be straight with you – it’s a tough start. There’s zero decent surf on offer through the entire 16-day stretch. Not a single day scores above a 1-out-of-10 quality rating, and even that one is described as “surfable waves but very ordinary conditions.” We’re looking at a long, dry run here, basically from now right through until Wednesday, 23 September. That’s a solid gap of over two weeks with no real recommendations.

For the first break in the water, Rehoboth Main is a beginner-friendly spot, exposed to swell, and it’s always crowded. It’s right on the beach, so you know what you’re getting. On Tuesday morning, 8 September, it’s clear with a light northwesterly cross-off breeze and wave heights of just 1.0ft, period of 9 seconds from the east, with combined wave energy sitting at only 18 (weak). The water temperature is a very unusual 77°, which is 5° warmer than normal for this time of year – that’s pretty notable. But honestly, it’s poor surf conditions.

From the 8th through the morning of the 10th, the swell stays tiny – mostly under 3ft – with periods bouncing between 4 and 10 seconds. Winds are mostly cross-off or onshore making the surface a bit messy or clean but with no guts. The best quality comes on Thursday morning, 10 September, when it’s cloudy, a moderate offshore from the WSW at 16 mph cleans up a 2ft, 6-second south swell. Combined energy is 40 (weak). It’s surfable but ordinary.

Then from Friday 11th into the second week, it’s a mess. Onshore winds, short periods, and wave heights rarely top 3ft. There is a little bump on the afternoon of Sunday 13 September – 3ft from the SSE at 5 seconds, with combined energy of 65 (weak) and a light cross-on wind, but still poor quality. Monday 14 September offers a brief moment of absolute glass in the afternoon with a 1ft south-east swell at 9 seconds, combined energy 26 (weak) – it’s clean but tiny.

Into the second week, nothing changes. Swells remain small and disorganised. The 19 September brings a bit more size with a 4ft north-easterly early, period 5 seconds, combined energy of 79 (weak), but winds are cross-onshore and choppy, making it poor. The very end of the forecast period on 23 September sees a 3ft east-south-east swell, period 8 seconds, combined energy 76 (weak), but onshore wind kills it.

This is a classic blank run for Rehoboth Main. With most records showing “poor surf conditions” and only the one “ordinary” moment, it’s one of those times where you just have to wait. Forecasts can change, but right now, there’s nothing worth paddling out for.

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.
