The Lowdown
Alright, let’s break it down. Rusty here.
Looking at the next 16 days for Shichigahama, it’s a real bummer. The surf is flat to tiny the whole time. No solid swell at all. The waves are all under 2ft, with weak energy. The best we see is combined energy of 89 late in the month, but that’s still weak. The water temp is about 77°F, which is normal for the season.
Wednesday the 15th starts with a 1ft SSW swell, but the wind is cross-onshore and the period is 9 seconds, so it’s just messy. No dice. Thursday the 16th morning goes glassy, and the swell is 2ft from the SSW, but the period drops to 5 seconds – that’s windswell with no power. The whole forecast is a string of poor surf. Friday the 17th through the 22nd is all sub-2ft, short period, and mostly onshore or cross-onshore winds. There’s a moment on the 22nd morning with a strong offshore wind from the NNE at 18 mph, but the swell is only 2ft with a 6-second period, so it’s clean but tiny. Not worth it.
The second week doesn’t get any better. The 25th shows a little bump with 2ft from the S on Saturday morning, but the period is 5 seconds and the wind is cross-off, so it’s clean but gutless. The 27th sees the combined energy hit 82-89, but still only 2ft and a 10-second period, with cross-on or cross-off winds. The 30th Thursday afternoon has a longer period of 16 seconds from the SE, pushing combined energy to 122 (moderate wave energy), but it’s only 1ft and cross-on. A tease.
Honestly, there’s no standout here. For a river mouth like Shichigahama, it’s inconsistent at the best of times, and this run is a total blank. If you’re desperate for a paddle, the 25th morning or the 27th morning might offer a clean little knee-high ripple, but don’t expect a wave. It’s a stretch of flatness that lasts nearly the whole 16 days. The setup is more interesting for a kite surfer than a paddle surfer, if there’s any wind.
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.
