The Lowdown
Alright folks, Rusty here. Let’s be straight with you. I’ve looked over the stretch ahead for Whipsiderry, and I’m calling it like I see it: this is a tough run. We’ve got a full 16 days on the table, but honestly, there’s not one single session that pops as a clear standout. The whole window looks like one long battle with messy wind and poor surf quality, with no real green lights for a good paddle.
We kick off on Sunday the 16th with tiny, weak 1ft swell from the west, only a 7-second period, and combined energy is a paltry 25. Onshore wind from the northwest is already messing it up. Monday the 17th sees a slight lift to 3ft, still short-period junk with a 104 combined energy, but that WNW wind stays onshore. This pattern sticks through Tuesday the 18th and Wednesday the 19th, with swell building to 6ft – 7ft, but the wind swings cross-onshore and gets fresh, bumping energy up into the 300s and 400s. It’s lumpy, choppy, and honestly not surfable.
Thursday the 20th into Friday the 21st gives us the biggest pulse of the first week – 6ft to 6ft from the WNW, with periods stretching to 9 seconds and combined energy hitting 594 and 572. That’s moderate energy, and the wind is onshore or cross-onshore. Add in rain showers, and it’s just not clean. Saturday the 22nd and Sunday the 23rd drop back to tiny 1ft to 2ft slop with weak energy in the 50s. The water sits at a very unusual 67°, which is much warmer than normal for this time of year, but that doesn’t help the waves.
The second week is no better. Monday the 24th bottoms out with 1.0ft and a combined energy of 28, and Tuesday the 25th is not much better. Wednesday the 26th shows a flicker of hope with 2ft to 4ft and offshore wind from NNW and WNW, giving us clean conditions and combined energy of 137 to 155. But the period is short (7 to 9 seconds) and the swell is small, so it’s marginal at best. It’s not nearly enough to call a standout. That modest energy fades quickly, and by Thursday the 27th, cross-onshore wind returns with 5ft swell, and the rest of the run into the 31st is dominated by strong, messy winds from the west and northwest, with swell fluctuating between 4ft and 10ft. The biggest day is Saturday the 29th with a 10ft swell from the west at 9 seconds, but combined energy is a massive 1366 – that’s strong energy, but with strong cross-onshore winds and lumpy conditions, this setup is better suited for kite surfing than a traditional paddle session. It’s big, raw, and blown out.
Look, Whipsiderry is a fairly exposed spot that usually gets a fair share of WNW swell, but the wind just never cooperates. The break itself is fairly consistent, but the conditions this time around are a write-off. There are just no good surf options in this 16-day window. For this area, a blank run like this is more normal; it tends not to stay this poor for long, and forecasts can change. But right now, I’d save your energy. Hang loose.
