The Lowdown
Alright, Rusty here, lookin' at what we've got for the next couple weeks. To be honest, it's a tough stretch ahead for Galveston-Flagship Pier.
Right off the bat, the water temp is reading 87°, which is a touch warmer than normal for this time of year. You'll be in a t-shirt for sure.
We're looking at a pretty blank run here. The whole 16-day forecast is just a string of poor surf conditions with scores that are a big fat zero. There's no real standout session to get excited about. The combined swell energy is in the low double digits for most of it, just small leftover energy. For example, Saturday the 15th morning, we've got a tiny 2 ft swell from the southeast, but that's bumped up by a cross-onshore wind at 9 mph, making it choppy. That same afternoon, the wind picks up to 12 mph and it's still messy.
The only hint of something glassy is early Sunday morning, the 16th. The wind goes to 3 mph from the west—totally glassy. But the swell is a pathetic 1 ft from the SSE, with a combined energy of just 13. It would be flat and clean, but that’s about it. Monday morning the 17th looks clean with a light offshore breeze from the west, but again, you're looking at ankle-snappers at 1 ft.
For the rest of the period, it's more of the same: small swell, mostly under 2 ft, with onshore or cross-onshore winds that will keep the surface messy. By the time we get to the 26th, there's a brief moment of clean conditions with a 6 mph offshore from the NW on Wednesday morning, but it's still just 2 ft of short-period slop.
Honestly, for a surf setup that's a beach/pier and pretty exposed to the southeast, this is a tough run. If the wind was lighter or offshore with this small swell, you might get some knee-high peelers, but the wind direction is just wrong most days. A setup like this with these winds and small swell is honestly more interesting for kite surfing than for paddle surfing. Keep your board in the car for now—maybe something will change, but it's not looking likely.
Rusty.
