The Lowdown
Alright, Rusty here, let’s have a look at what’s on offer for Rehoboth Main.
Honestly, the next 16 days are looking pretty flat and quiet. This is one of those stretches where the ocean just isn’t putting out. The first real chance to even mention a wave is Friday the 7th of August, and even then, it’s marginal. The swell is tiny, only 0.7m from the south with a short period of 5 seconds. The wave energy is weak (47). It’s surfable, but only just. The wind is a cross-off from the SW at 15 km/h, which keeps the surface clean, but there's no push behind it. This is beginner territory, but honestly, it’s not really worth getting wet for.
All through Saturday the 8th and Sunday the 9th, we’re stuck in the same rut. Tiny 0.4m to 0.8m south and southeast windswell, with a combined energy never breaking 100. The wind on Sunday shifts a little more offshore from the WSW at 10 km/h, which cleans things up, but the waves are just too small to get excited about.
Monday the 10th brings glassy conditions with a SW wind at only 5 km/h in the morning, but the swell is only 0.5m and the energy is a mere 23. It’s flat, mate. This pattern of low energy and small swell continues right through to the end of the second week. The water temperature is 24°, with a 0.5° anomaly, so it’s right around average for this time of year.
There’s really no standout window here. The most promising breeze comes on the morning of Tuesday the 18th of August, with flat calm glassy conditions and a tiny 0.4m southeast swell, but the energy is still negligible. Then on Thursday the 20th of August, we see a 0.4m SE swell with a period of 10 seconds and energy of 40, with a light offshore wind from the WSW at 10 km/h. That’s about the best we get, and it’s still a very small, weak wave. For a spot that is exposed to east swell, this south and southeast direction just isn't delivering.
Because the swell is so small and weak across the entire period, and Rehoboth Main is always crowded, there isn't a single standout. This is a long stretch of poor conditions. The setup is more interesting for a kite surfer than a paddle surfer given the constant wind and lack of wave power.
Rusty.
