Table - best surf conditions forecast for James Kealoha Beach Park over the next 16 days.
Alright folks, Rusty here. Let’s be straight with you – this 16-day window for Hilo side is looking pretty grim for a proper paddle. The data shows a long stretch of onshore winds and weak, short-period windswell that just won’t line up. We’ve got a solid gap of nothing worth your time from the start, all the way through until the end of the third week.
The only spot worth a mention in this whole forecast is James Kealoha Beach Park (Big Island) . It’s a reef setup, exposed to the north-east, which is the direction it wants for optimum swell. It’s rated as fairly consistent, but you wouldn’t know it from this run. The water temp is sitting at 80°, which is about average for this time of year, so no surprises there.
The first real glimmer of hope doesn’t show until Tuesday, July 22nd on the morning. That’s a solid 10-day wait from the start of the period. The early morning on the 22nd is the standout. We’ll see a 4ft swell from the ENE, with a period of 8 seconds. The wind is light and cross-offshore from the east, which will keep it clean. The combined energy is moderate (284). It’s not a big swell, but it’s the only window where the conditions are actually decent for a surf. The rest of that day, the wind swings cross-shore in the afternoon, making it a bit ordinary.
Before that, everything is a write-off. From Saturday the 12th through to Monday the 21st, the forecast is a mess of rain showers, cross-onshore winds, and choppy conditions. The swell heights bob around from 3ft to 6ft, but the period is a short, weak 6-8 seconds, and the wind is always wrong. The combined energy hits a peak of 484 on the Sunday the 12th, but with a cross-onshore wind and short period, it’s just a messy, poor-quality wave. It’s more of a kite surf setup than a paddle surf.
So, if you’re holding out, pencil in the morning of Tuesday, July 22nd at Kealoha. It’s the only clean, surfable window in the whole 16-day outlook. After that, it’s back to poor conditions and onshore winds through the rest of the month. The long-range outlook is promising but less certain, so keep an eye on it.
Rusty.
