The Lowdown

Alright, this is Rusty. Let’s have a look at what’s on the cards for Shichigahama over the next couple of weeks.

First off, I’ve got to be straight with you – the start of this run is a bit of a flat spell. There’s a block of days where the surf is just too poor to get excited about. We’re looking at a gap of about four days before anything really worth paddling out for shows up.

The real standout in this forecast is Monday morning, the 24th of August. That’s the one to circle on your calendar. The swell is still small at 2ft from the SSE, but it’s a long-period groundswell of 19 seconds, which gives it some real push. The energy reading is a solid 482 – that’s moderate energy, but for the size, it’s packing a punch. The best part? Glassy conditions. Absolute zero wind. It’s going to be clean as a whistle. With the water sitting at a warm 81°F, and the anomaly is only 0.5°F above normal, so it's about average for this time of year. This is a sneaky good session for a river break, where that long-period swell can really line up. Just keep in mind, it’s an inconsistent spot, so don’t expect a wave every minute, but the ones that come through will be worth the wait. Crowds are possible here, so get in early.

Now, moving on. The next blip of interest is Thursday, the 3rd of September. The morning looks promising with a 5ft swell from the SSE, period of 11 seconds, and a moderate offshore wind from the NE. That’s clean, and the energy is a healthy 526. It’s a solid intermediate wave. The afternoon drops off a bit with a 4ft swell and a cross-off breeze, but it’s still surfable. That morning session is the better bet.

Then, the last real highlight is Sunday morning, the 6th of September. Another 5ft SSE swell, this time with a 14-second period. The wind is cross-off from the NE, so it’s clean. The energy is up to 969, which is strong. This is again a decent wave, but remember, this is two weeks out, so the confidence is lower. The swell direction is a touch off from the optimum, but it’s still worth a look.

For the rest of the days, it’s a mixed bag of onshore winds, shorter periods, and small, weak swells. There’s a couple of mornings with clean conditions and knee-high waves, but nothing to rush for. The long-range stuff on the 6th is the most promising of the later week, but we’ll have to see how it firms up.

Stay safe, and don’t force it on the flat days.

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.
