The Lowdown
Alright folks, Rusty here. Let's be straight with you. The next couple of weeks are looking pretty grim for a proper paddle. We're staring down the barrel of a long stretch of small, messy surf. It’s not going to be pretty for a while, so maybe keep the board in the car and the kite gear handy.
Looking at the opener, and the first real chance of anything decent, Rehoboth Main is the only spot on the map. The water's sitting at a very unusual 77°, which is nearly 5 degrees warmer than normal for this time of year—that’s a real treat when you do get out. But the surf itself is the problem. For the next several days, we're looking at weak, short-period swell, often under 3ft, with lousy winds. The energy is just pitiful, with combined readings struggling to get past the 50s (37, 20, 29). Thursday the 10th might have a clean morning with a light offshore, but the swell is only 2ft with a 6-second period. Glassy, but barely a ripple. It stays that way through the weekend; Friday the 11th is cross-on and choppy, and Saturday the 12th sees a bit more size, maybe 3ft, but the period is a dismal 4-5 seconds and it’s chopped up. Not worth your time.
There's a tiny glimmer on Monday the 14th. The wind goes cross-offshore and it cleans up, but the swell has dropped to a thigh-high 1.3ft. You might catch a crumbly little one if you're desperate, but the energy is still weak (maximum of 40). We then slide back into a bumpy mess for the rest of the week. The second week is just as bleak. There’s a pulse of energy around Friday the 18th, with the combined energy jumping to 150, and the swell pushing to 5ft. But it's coming from the ENE, which is onshore for this set-up, and the period is short at 6-7 seconds. It'll be a wind-blown mess.
The one thing that catches my eye is the jump in energy on Monday the 21st. We're talking a combined energy of 441-500, which is a serious step up in power, and the swell is up to 6ft. But it’s coming from the ENE with a short 8-second period and a strong cross-onshore wind at 25-28 mph. This isn't a clean groundswell; it's just raw, lumpy, and messy. At that size, with that wind, they'll be closing out and it’s only going to be interesting for the experts, and even they'll be fighting it. This one's a pass for a paddle.
Honestly, if you're looking at that period with the strong wind and the messy 6ft waves, it’s going to be a better show for the kiteboarders than the surfers. For us, the best we can hope for is Tuesday the 22nd, when the wind finally swings offshore in the afternoon and it cleans up, but the swell has dropped back to 3ft. That might be the only semi-surfable wave of the entire stretch, and even then, it's average at best.
Hold tight, and check back. Forecasts change, and with this much warm water around, it won't stay this flat for long.
