Kanegahama Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s get straight into what’s happening at Kanegahama.

Right off the bat, we’ve got a solid run of big, powerful swell hitting the beach, but it's a case of too much of a good thing. For the first few days, from Thursday the 9th right through to Saturday the 12th, we’re looking at a massive pulse of southerly groundswell with wave heights punching 10 ft to 13 ft, and the combined energy of all swells is absolutely cooking – peaking at 9358 on Saturday. These are expert-only numbers. The period is a long 15 to 17 seconds, which will be stacking up and dumping heavy. The water here is sitting at 78°, which is a bit colder than normal for this time of year, so you might want a thin spring suit. For a beginner spot, this is a major no-go. The wind is light cross-onshore through the early days, which won't clean it up enough for the size.

Now, Sunday the 12th morning is where we see a real turnaround. The swell drops to a much more manageable 7 ft from the south, period settles to 13 seconds, and the combined energy drops to a moderate 1694. The best part? Glassy conditions. This is the standout window for experienced surfers who can handle a solid, powerful wave. The break is fairly consistent, so you won't be waiting forever. Expect some crowd, as it gets busy here sometimes.

Monday the 13th morning is another real treat. The swell backs down to 5 ft from the south, period 11 seconds, and it’s totally glassy, calm wind. The energy is a weak 561, but the shape will be good. This is perfect for a wide range of surfers, just a clean, fun, long-period groundswell that will offer some nice lines. The afternoon sees a bit of a risk of thunderstorms, but still glassy and smaller at 4 ft.

From Tuesday the 14th through to Saturday the 18th, we go into a flat spell. The swell drops to knee-high, with combined energy values in the double digits, under 165. Wind is light and variable, but there is just no power. It’s a full gap of around four days with nothing worth paddling out for.

Then we get a flicker of life on Sunday the 19th. The swell picks up to 5 ft from the ESE, period 13 seconds, and energy bumps to 1023. The wind is light cross-shore, which is surfable, but the forecast calls it marginal. The next day, Monday the 20th, builds to 8 ft, then Tuesday the 21st sees a massive spike: 18 ft from the SE with a 14-second period! The energy is a staggering 13421. This is a monster swell, glassy in the morning, but way too big for this break. That’s a big, big watch from the safety of the sand.

For the final few days, Wednesday the 22nd morning looks promising with 6 ft from the ESE and glassy conditions, but the period is a short 8 seconds, so it will be a bit crumbly. Thursday the 23rd afternoon is a highlight: 5 ft from the SSE, 12-second period, with 810 energy and glassy conditions. That’s a nice, clean, lined-up wave. Friday the 24th morning is the last real standout: 8 ft from the SSE, 12-second period, 1766 energy, and glassy. That’s a powerful, clean wave for experienced surfers again.

So, to sum it up: the best windows are Sunday the 12th morning and Monday the 13th morning for the first week, then Thursday the 23rd afternoon and Friday the 24th morning for the second week – but those later ones are a bit further out, so keep an eye on it.

Rusty.
