The Lowdown
Alright, Rusty here again. Let’s talk about what’s going on at Rehoboth Main.
Honestly, it’s been a real struggle to find anything decent. The next week and a half is looking pretty grim, with hardly any surf worth paddling out for. We’ve got a big gap from now until the 22nd of September where the conditions are just too poor to recommend. There’s a tiny bit of swell here and there, but the wind is all wrong or the period is way too short.
Let’s be real: September 12th through to the 21st is a write-off. You’ve got tiny swell mixed with onshore winds or messy cross-shore chop. It’s just not worth getting wet. The water temperature is sitting at a balmy 76°F with a whopping 5°F anomaly, so it’s much warmer than normal for this time of year, but that’s the only good thing.
Now, the first real glimmer of hope comes on the 22nd of September. The combined energy starts to build, but the wind is still a mess. The real standout window is the 23rd of September. Wednesday morning and afternoon are the absolute best on offer. You’ve got a solid groundswell from the ENE pushing 8 ft to 8 ft with a period of 8 to 9 seconds. That’s proper size, and over 8 ft is strictly for experts. The wind cleans up with offshore W winds, going from a gentle to moderate breeze. The wave comment even says “expect very good surf conditions,” and I can’t argue with that. The combined energy jumps right up (724 to 955), showing there’s plenty of power. This is your window if you’re skilled enough.
The 24th of September keeps the size, with swell around 8 ft from the E with a 10-second period. The wave energy is massive (1131), but the wind gets tricky again – strong cross-off in the morning turning to a lumpy cross-shore in the afternoon. It’ll be a handful.
After that, the swell drops off and the wind stays messy through to the end of the run. It’s really just that Wednesday the 23rd that’s the standout. Get on it if you can handle it.
