The Lowdown
Alright folks, Rusty here. Let’s be straight with you – the next 16 days at Rehoboth Main are a tough watch. The forecast is littered with tiny, weak swell and poor conditions, making it a real struggle to find anything worth paddling out for. The combined wave energy barely cracks double digits for most of the run, sitting at a measly (18) on the first morning. We're looking at a long, flat spell.
There’s a chance the wind goes offshore on the morning of Thursday the 10th of September, with a light westerly breeze. The swell is only 3ft from the south with a short period of 6 seconds, so it’s weak and very ordinary. The energy is still low at (45). It’s surfable, but it’s not going to get the heart racing.
The pattern doesn’t really improve. We see a little bump in the energy on the 16th of September with a couple of afternoons hitting (70) from the ENE, but the swell is only 3ft and the period is a paltry 5 seconds – that’s just wind chop. The wind is clean cross-off from the NNW, but the waves will be crumbly and weak.
Honestly, the best looking window arrives on Friday the 18th of September. The afternoon shows a clean 2ft easterly swell, with a period of 7 seconds and a combined energy of (60). The wind is light and cross-off from the SW. It’s still small, but it’s the cleanest and most organised we’ve seen in a while. For a beginner, that’s about as good as it gets around here.
The last bit of hope is Sunday the 20th of September. The morning offers a clean, light breeze and a 1ft south-east swell with a period of 10 seconds. The energy is only (44), but that longer period might give the tiny waves a bit of shape. It’s not a standout, though.
The rest of the 16 days? It’s a desert. The swell is tiny, the wind is often onshore or cross/onshore, and the majority of the time the surf is rated as poor. With Rehoboth Main being exposed and always crowded, there’s nothing to get excited about. This is a proper blank run for the area. For a spot that’s fairly consistent, it’s a real bummer, but forecasts can change.
Stay patient,
Rusty
