The Lowdown
G'day, I'm Rusty, and I've got the local skinny on the surf ahead.
Alright, let's be straight with you – the next 16 days are a flat spell for Galveston - Flagship Pier. We're looking at a real dry patch here, so don't get your hopes up for anything rideable. The water's sitting at a warm 87°F with a touch warmer than normal anomaly, so it's more of a swim than a surf session.
The pattern starts with Thursday afternoon, August 20th, and it's a write-off. We've got a tiny 1ft swell from the S with a period of just 4 seconds, and a cross-on 16 mph wind from the S. The combined energy is a measly 7 (weak energy), and it's just poor surf conditions. That's the story for the first few days – Friday morning, August 21st, does offer a clean look with a WSW wind at 6 mph, but the swell is still a pathetic 1ft. It's like a lake out there.
We roll through the rest of the weekend and into the next week with the same vibe. Swell heights barely nudge up to 2ft on Saturday morning, August 22nd, and again on Wednesday morning, August 26th, but the periods are all around 4-5 seconds. The wind is mostly cross-on or onshore, keeping things choppy and messy. The combined energy stays in the low double digits, like 21 (weak energy) on Saturday afternoon, and 23 (weak energy) on Thursday morning, August 27th. That's your "biggest" energy spike, and it's still tiny.
There's a gap of solid days with no real surf on offer. The best we can say is that the break is fairly consistent, but right now, it's consistently flat. Forecasts can change, but for this outlook, it's a blank run. For what it's worth, with these conditions – weak swell, poor quality, and strong onshore wind at a beach/pier setup – it's looking more interesting for kite surfing than paddle surfing.
Hang in there, and keep an eye on the horizon. Sometimes these lulls break quickly.
