Alright, let’s talk A-Bay. The next couple of weeks are mostly on the small side, with a long wait before anything really gets going. You’ll be sitting on your hands for a while.

The real standout is Tuesday, July 14th. That’s the day. Morning brings a 2ft, 19-second groundswell from the west, with combined energy hitting 350 – that’s solid moderate energy. Wind is glassy, calm from the northwest, so the water will be like a sheet of glass. Perfect for the intermediate surfer. The point at Anaehoomalu Bay (Big Island) will love that long period. Just keep in mind, crowds can show up here sometimes. Water temp is about average for the time of year.

Tuesday afternoon gets even better – 3ft, still 18 seconds from the west, energy cranking to 404, and glassy again with those rain showers. That’s the best of the whole forecast.

Before the 14th, it’s a slog. From now through the 11th, it’s mostly flat or tiny waves up to 0.3ft, with weak energy in the single digits or low tens. Winds are cross or cross-off, nothing clean, and the conditions are poor. There’s a big gap of almost nothing worth mentioning.

On the 12th, Sunday afternoon, there’s a little hope – 1ft from the southwest, 16 seconds, glassy, but energy is only 144 and it’s just “surfable but very ordinary.”

The 13th, Monday afternoon, sees a 2ft west swell at 15 seconds, glassy, energy at 157, but still just “surfable.”

After the 14th peak, it drops off quickly. The 15th has 3ft but cross-on wind and marginal conditions. The 16th afternoon has another glassy window with 2ft at 15 seconds, energy at 215, but it’s still just “surfable.” The rest of the run into the 20th fades into tiny, weak stuff and poor conditions.

So, bottom line – Tuesday, July 14th is your day. Morning and afternoon both look clean with that nice west groundswell. Everything else is pretty quiet.

Rusty.
