The Lowdown

Alright, Rusty here. Let’s talk about what’s on the cards for the next couple of weeks.

First up, the overall pattern. The first few days have some serious size, but it’s a bit of a mixed bag for conditions. We’ve got a good window of clean surf early on, but it gets real small and windy in the middle of the run. The real standout is the opening morning, and there’s a bit of a promise late in the second week, but don’t hold your breath on that one just yet.

Wednesday, August 5th is where it’s at. Shichirigahama is looking like the spot to be. The morning is clean with a moderate offshore breeze, and the swell is a solid 7ft from the SSE with a long 15-second period. That’s a proper groundswell with plenty of energy (2348). The water is a touch warmer than normal at 84°F, which is a nice bonus. This is quality, powerful surf, but at 7ft, it’s one for the experienced crew – beginners should sit this one out. The wave conditions are “excellent,” so you know it’s on. The afternoon holds similar size but the wind swings cross-offshore, so it’s still rideable but not as clean as the morning.

Thursday, August 6th rolls in with a drop in size. The morning is still a decent 6ft swell from the SSE, but with that cross-off wind, it’s clean enough. The energy is still moderate (1105). The tide could be a factor here, so keep that in mind. The afternoon is a write-off with onshore wind.

Friday, August 7th through to Sunday, August 10th sees the swell fade and the wind become a problem. The swell drops from 6ft down to 2ft, and the winds are mostly onshore or cross-onshore, making for a pretty poor outlook. Saturday morning has a tiny window of a light cross-shore breeze with 5ft swell, but it’s marginal at best. The combined energy is dropping fast (767 down to 179). It’s a bit of a dead period.

Monday, August 11th through to Monday, August 18th is a flat spell. We’re looking at just 1ft to 2ft of swell, and the winds are fresh to strong, mostly offshore. That offshore wind is clean, but with that little swell, there’s nothing to ride. The energy is weak, reading under 100 most days. This is a solid week of no real surf.

Tuesday, August 19th is where things get interesting again. The swell jumps back to 7ft from the SSE, but the wind is a cross-onshore mess, making it choppy and poor. The energy is strong (1688), but the quality is not there. Not a good day for a paddle.

Wednesday, August 20th has a bit of a last gasp. The swell is still a solid 7ft from the SSE, but the wind is onshore. The score is a bit better, but the onshore wind will ruin it. A real shame, because the energy is there.

So, the best of the best is Wednesday morning, August 5th at Shichirigahama. That’s your window. After that, it’s a long wait until the second week, and even then, the conditions are sketchy. Keep an eye on the forecasts, because a week of nothing can change fast.

Rusty.

Information about the Shichirigahama Surf forecast

The above surf forecast table for Shichirigahama provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Shichirigahama can be found by selecting the local surf guide option on the grey menu. Our Shichirigahama 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 (Shichirigahama) 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 Shichirigahama 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.
