The Lowdown
Well, folks, Rusty here. I gotta be straight with you – the next 16 days at The Reef (Culebra) are looking pretty grim. This reef break is usually consistent, but the swell direction is all wrong (mostly NE/E) for its north-facing exposure, and the waves are tiny, short-period junk. Combined energy barely cracks 100 most days, often sitting in the weak range (56–91). Water temperature is sitting at 84°F, about normal for this time of year, but that’s the only thing that’s average.
The whole period from now (21 July) right through to 5 August is a long stretch of poor surf. There’s one solitary moment on Tuesday afternoon, 4 August, where the forecast shows a marginal chance – 5 ft from E with a 6-second period, combined energy 213 (moderate), and clean cross-off wind from ESE at 12 mph. That’s the only thing that might be rideable, but it’s still a marginal call, and the tide could mess it up. For beginners, anything over 5 ft is pushing it, but here the issue is the short period and cross-shore wind most days.
Honestly, there’s no standout in this window. If you’re desperate, maybe have a look that Tuesday afternoon, but don’t expect much. The reef needs a proper N swell with clean offshore winds to light up, and we’re not getting that. This is one of those blank runs that can happen in summer – forecasts can change, but right now it’s a flat spell.
Stay tuned, Rusty.

Further information to help with frequently asked questions about our surf forecast for The Reef (Culebra) may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself.
