The Lowdown
Alright, Rusty here. Let’s talk about what’s on offer for Kanegahama over the next couple of weeks.
First things first, this spot is a beginner-friendly, exposed beach break that loves swell from the SE. It’s fairly consistent, so it’s got that going for it, but the start of the outlook is a write-off. Sunday the 23rd is flat and poor, so we’re looking at a gap right out of the gate.
The first real chance to get wet comes Monday morning, the 24th. It’s small, around 3ft of SE swell, but the wind is glassy and offshore from the NE. That’s clean, and the water is sitting at a warm 83°, which is pretty much dead average for this time of year. The wave energy is moderate (405), so it’s a good time for a beginner to get some practice in without getting worked.
The standout action is Tuesday the 25th. The swell pumps up to 13ft from the SE with a 15-second period – that’s proper groundswell energy, and the combined energy is massive (6676). The wind is light and cross-offshore from the NE, making it look clean. But here’s the catch: for a spot like Kanegahama, a 13ft swell is a lot. It’s really only for experts. Beginners should stay well clear. The period is long, so the sets will have some punch and be more suited to the lineup, but it’s still a beast.
Wednesday the 26th is still big, with 10ft and 12ft, but the wind turns cross-on and it looks a bit messier. The energy is still strong (3375 and 2114), but the risk of thunderstorms and the wind direction aren’t doing it any favors.
By Thursday the 27th, the swell drops to a more manageable 6ft from the SSE. The wind goes glassy in the morning, and the surf is expected to be very good. The period is a short 9 seconds, so it’s a bit windswell-ish, but the clean conditions will make it fun. Energy is moderate (561).
Friday the 28th morning is a good call too – 4ft of S swell, glassy calm wind, and clean. The period is short (8 seconds), so it’s not gonna have huge power, but it’s super user-friendly. The afternoon goes onshore and poor, so get it early.
The weekend of the 29th and 30th is a mixed bag. Saturday morning has glassy conditions and 4ft, but the afternoons are blown out. Sunday morning the 30th is glassy with 3ft, but the energy is weak (153). It’s surfable, but not exciting.
Monday the 31st is tiny in the morning, then picks up a bit in the afternoon. Nothing to write home about.
Heading into the first week of September, Tuesday the 1st sees a new pulse of 6ft to 6ft SE swell with a 12-13 second period. The energy is good (826-1283), but the wind is cross-shore and cross-on, so it’s going to be a bumpy. Wednesday the 2nd gets bigger, up to 8ft, but the wind is howling from the NE at 16 mph, creating a cross-chop. This is getting into kite-surfing territory rather than clean paddle surfing.
The rest of the forecast into the second week is pretty grim. The swell stays big, over 8ft, but the wind is consistently strong, cross-shore, and often rainy. Friday the 5th sees a massive 18ft swell with a 28 mph NE wind and gale-force conditions on Saturday. That’s not for surfing; that’s for watching from the beach. The energy is through the roof (5812 and 3000), but it’s a total mess.
The light at the end of the tunnel is Monday the 7th of September. The swell drops right back to 3ft from the E, with a clean, light cross-offshore wind from the WNW. The energy is moderate (345) and the conditions are clean. It’s a small, mellow end to the run.
The best bet: Get on the Tuesday 25th morning if you are an expert and want to charge a big, clean, long-period SE swell. For everyone else, the glassy, small windows on Monday 24th morning, Thursday 27th morning, and Friday 28th morning are your best, safest options.
Rusty.

Information about the Kanegahama Surf forecast
The above surf forecast table for Kanegahama provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kanegahama can be found by selecting the local surf guide option on the grey menu. Our Kanegahama surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Kanegahama) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Kanegahama may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
