The Lowdown
Alright folks, let’s be real about Galveston – Flagship Pier for the next couple of weeks. It's going to be a quiet, underwhelming period. We’re talking small, weak, and mostly poor conditions.
Water temp is sitting at a noticeably warm 87°F, a touch above the norm, which is about the only thing that’s heated up around here.
Today, the 14th, it’s all onshore junk. A tiny 2ft SSE swell with a weak energy reading of 32. It’s a write-off. The weekend follows suit. Saturday the 15th is more of the same, small and crumbly. Sunday the 16th does show a bit of morning glass with a light breeze, but the swell is just 1ft. It’s flat, dead water.
The whole stretch from the 17th through the 22nd is stuck in neutral. Swell heights hover between 1ft and 3ft, with short periods of 4 to 6 seconds. There are a few clean windows. Monday the 17th morning has a light offshore breeze, and Saturday the 22nd morning turns glassy, but the swell is still tiny and weak. These are the only times the water looks semi-tempting, but it’s still just ankle to knee high junk for the most part. It’s a good time to work on your pop-up on the sand or just enjoy the beach.
The rest of that week is a blur of cross-shore breezes and small, choppy slop. The wind picks up, especially around the 18th and 19th, stirring things up, but the energy just isn't there to make anything of it.
The second week, from the 23rd on, doesn't offer any relief. The swell is consistently tiny, between 0.7ft and 2ft, with periods dropping to 4 seconds. There’s one morning on the 25th with a slightly larger 2ft swell, but it’s still weak and crossed up.
So, the only real, if small, opportunity sits with those light-wind mornings, specifically the 17th and 22nd. You’ll get a clean, knee-high wave with the right wind. It's a skate session, not a surfrider's paradise, but it's all we've got.
This is a common kind of flat spell for this area. It can be a test of patience. But the ocean's always changing, and a little pulse could show up on the forecast anytime. Keep an eye on it, but don't hold your breath.
