The Lowdown
Alright, let’s break it down for the Imperial guys.
First up, we got Galveston - Flagship Pier. Look, I gotta be straight with you – it’s a tough stretch ahead. The water temp is sittin’ around 86°, which feels pretty average for this time of year, nothin’ wild.
Right now, we’re lookin’ at a run of flat, poor conditions. The swell energy is barely registerin’ – we’re talkin’ single-digit numbers for the first week and a half. That’s weak, real weak. The swell heights are tiny, mostly under a foot and a half, and the period is short, around 4 to 6 seconds. That’s just wind slop, nothin’ with any push. On top of that, the winds are mostly cross or cross-on, keepin’ things choppy and messy.
There are a few mornings where it cleans up, like Sunday the 19th and Wednesday the 22nd, with light offshore or cross-off breezes, but the swell is just too small to make anythin’ happen. You’ll be bobbin’ around on a knee-high ripple at best.
The best look of the whole 16 days might be towards the very end – around Friday the 31st of July into Saturday the 1st of August. The swell height bumps up a bit to about 3 ft, and the period stretches to 6-7 seconds. The combined energy climbs into the 50s and 60s. That’s still only moderate energy, but it’s a whole lot more than we’ve seen. The wind isn’t perfect – got some onshore and risk of storms – but there’s finally some swell to work with. Keep an eye on that Friday morning the 31st, with a clean offshore wind from the west and that 3 ft SSE swell. It’s the one session in the whole run that might give you a few rideable, if a little soft, waves.
Overall, it’s a long dry spell. You’re lookin’ at a solid 12 days of real poor surf before anythin’ worth paddlin’ out for shows up. Hang in there.
