The Lowdown
Alright folks, Rusty here. Let’s be straight with you – this outlook is a tough one.
We’re looking at a 16-day window, and honestly, there’s nothing on the table that’s worth paddling out for. The whole run is a flat spell, with no surfable recommendations. The swell we’re seeing is tiny, with heights barely reaching 1 ft to 3 ft, and the energy is weak – the combined energy readings are all in the low double digits, like 6 (weak) up to a max of only 59 (weak). That’s not enough to get a decent ride.
The winds are mostly cross-on or cross-shore, which keeps what little bump there is messy and choppy. On top of that, the period is short, hanging around 4 to 6 seconds, so there’s no push or power. For a spot like Octagon House, which is a beginner-friendly break, it’s just not doing anything. The water temp is a warm 86°, which is about normal for the time of year, but that’s the only nice thing.
You’re looking at a full 16 days of this. It’s a real bummer, but it happens. The good news is forecasts can change, and it tends not to stay this quiet for long.
Stay patient, and keep an eye on the charts.
Rusty.
