Righto, lets have a look at what's coming down the line for the next couple of weeks. It's a bit of a slow burn to start, but there is a window of proper quality if you can wait for it.

First up, we've got a few small, messy days to sit out. Monday the 6th is a write-off with rain showers and a 9 mph cross-shore wind making a mess of a weak 3 ft SE windswell. Not worth paddling out for.

Tuesday morning the 7th looks much better early. A clean 2 ft groundswell from the SSE with a 15-second period and a light offshore wind from the NE. It will be glassy and clean, but the swell is tiny. The energy is building though, with combined swell energy at a moderate 289. It's a tease of what's to come.

The real standout is Wednesday morning the 8th at Shichirigahama. This is the one to clear the diary for. We get a solid 5 ft SSE groundswell with a long 17-second period, pushing a strong combined swell energy of 1549. Best of all, it's clean with a slight cross-offshore breeze from the east. The swell is big enough to require some experience, so this is for the intermediate crew and above. The water temperature is a normal 74° for this time of year.

From Thursday morning the 9th through the weekend, the swell jumps up but the wind turns onshore from the south. Thursday has a 6 ft S swell (combined energy 1300) with a light cross-onshore wind, so it's a bit bumpy but maybe worth a look if you're desperate. Friday the 10th gets bigger with a 7 ft S swell, but the onshore wind strengthens to 12 mph by the afternoon, making for poor conditions.

By Saturday the 11th, the swell peaks at 7 ft from the SSW (combined energy 2574) but with a 9-16 mph onshore wind, it becomes a blown-out mess. Sunday the 12th drops back to 4 ft but with 19 mph onshore wind. Not for the faint-hearted.

After that, there's a long dry spell. From Monday the 13th through to Saturday the 19th, the swell dwindles to under 2 ft and is constantly hit by onshore winds. Nothing to report, it's a proper flat spell.

Finally, Sunday morning the 19th offers a last chance. A clean 4 ft SE swell (combined energy 428) with a light cross-offshore breeze from the ENE. It is clean and surfable, but the period has dropped to 12 seconds. A decent little morning session before the onshores return in the afternoon.

So to wrap it up: the only true standout is Wednesday the 8th. Get on it early for clean, powerful waves. After that, it's a long wait until Sunday the 19th for a brief, cleaner window. The rest is blown out or flat.

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.

Shichigahama is 6 km (4 miles) from the city of Chigasaki. If you plan a holiday in Kanagawa, look for hotels and other accommodation in Chigasaki. Chigasaki has rooms for a wide range of budgets as well as car hire and transport links.
