Updates in hr min s Forecast update imminent
Alright folks, Rusty here. Let’s break down what’s headed our way.
Truth be told, the first week is a total snoozer. From now all the way until the morning of Saturday the 11th of July, there’s barely a ripple. Just tiny, clean conditions with no real swell to speak of at Kawaihae Breakwater. The water temp is about average for this time of year, nothing wild.
Things finally wake up on Saturday the 11th of July. We get a west swell creeping in at around 1 ft (0.4m) with a 14 second period, and the combined energy hits 111 – still weak, but it’s a start. That afternoon, the period stretches to 18 seconds and the energy climbs to 142. Winds are a moderate offshore breeze from the northeast, so it stays clean.
Sunday the 12th of July offers a bit more. The swell stays small at 1 ft (0.4m) from the southwest, with a 16 second period and energy around 148. The wind backs off to a light offshore, making for some clean little waves. Not the day to leave work early, but a fun longboard session.
The real highlight, and the best bet of the whole outlook, is Tuesday the 14th and Wednesday the 15th of July. On Tuesday, the swell pushes up to 2 ft to 3 ft (0.7m to 0.8m) from the west, with a very long 19 second period. Combined energy jumps into the moderate range – 397 to 450. Winds are light offshore, so it’ll be clean. Then Wednesday the 15th of July goes glassy – dead calm wind in the afternoon. The swell holds at 3 ft (0.8m), 16 second period, energy at 369. This is your window. Kawaihae Breakwater (Big Island) is a reef break, and that long-period west swell will wrap in with purpose. It’s an intermediate spot, so crowds are possible. For those who can handle it, this is the cleanest, most energetic swell of the run.
After Wednesday, the swell fades quickly. By Saturday the 18th of July, we’re down to 1 ft to 2 ft (0.4m to 0.5m) with dropping period. Still clean, but the energy is gone.
Bottom line: the first week is flat, so don’t bother. Target Tuesday the 14th and Wednesday the 15th of July at Kawaihae Breakwater for the best conditions.
Rusty.
