The Lowdown
Alright, Rusty here again, giving you the same story in feet and inches.
Let’s be real. The first few days are a struggle. On Friday the 7th, Shichigahama sees a south swell of about 5ft with a 13-second period. That’s got some kick (combined energy of 962), but the wind is a light cross-onshore, putting a little bump on the surface. It’s rideable, but not clean. The water temp is around 80°, which is about normal for this time of year.
By Friday afternoon, onshore wind ruins it. Saturday the 8th, the swell drops to around 4ft, still messy.
The only real window of opportunity is Sunday the 9th. The swell is tiny, only about 2ft, but look at the wind: a light cross-offshore. That means clean, glassy lines. The combined energy is low at 151, so it’s weak, but it’s the cleanest day in the whole run. You’ll need a longboard.
From Monday the 10th onward, it’s nearly flat. We get some nice offshore winds, especially from Wednesday the 12th through Friday the 14th, with a moderate to fresh offshore breeze. The water will be clean, but the swell is barely 2ft. The energy is in the 30s and 40s. It’s a tease.
The second week, from the 16th to the 22nd, is the same story. Offshore winds here and there, but the swell never gets above 2ft. The combined energy stays below 100 most days. It’s a long stretch of tiny, inconsistent surf.
The only standout is Sunday the 9th. It’s small, but it’s clean. That’s the best we’ve got.
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.
