Table - best surf conditions forecast for Big Ben over the next 16 days.
Alright crew, Rusty here, looking at the next 16 days for Big Ben. It’s a long window, and there’s a fair bit of nothing in it.
The first real chance to get wet is Monday, July 13th in the afternoon. We’re looking at a 4ft swell out of the SSW, with a 12-second period – that’s some proper groundswell energy. The water temp is about 77°, which is normal for this time of year. The wind is glassy, a light 5 km/h from the WSW, so the surface will be clean. The combined energy is a solid 559, which is a strong pulse. They’re calling for very good surf conditions. The swell direction is SSW, and while the spot likes SE best, the quality here is still a standout. Remember, this spot is inconsistent, so when it’s on, it’s on. It’s a beach/jetty break, and with 4ft waves, it’s a good size for most, not too big for beginners. Crowds can show up sometimes.
Tuesday morning, July 14th, drops to 3ft from the SSW with an 11-second period and glassy SSE wind. The energy is 238 – still decent but a step down. The afternoon turns sketchy as the wind swings cross-shore.
From Wednesday, July 15th, through the end of the first week, it’s a total bust. The wind is all cross, cross-on, or onshore, blowing 15 to 25 km/h. The swell drops to 2ft to 3ft with short-period junk. It’s poor surf all the way.
We get a tiny chance on Monday, July 20th afternoon. There’s a 4ft E swell with an 8-second period and glassy conditions. The energy is a weak 196, but it’s surfable and clean. It’s just nothing special.
Tuesday, July 21st, has a similar 4ft E swell, but the period stretches to 10 seconds, giving it a bit more push (energy 273). The wind is cross-shore, so it’s marginal.
The second week, from July 22nd onward, is a grind. Swell sizes bounce between 1ft and 5ft, but the wind is almost always a cross or cross-on breeze, making it choppy and poor. There’s a long-period 16-second SE swell on July 25th, but it’s only 1ft and the wind is a cross-on 15-20 km/h – a total tease. This is a beach/jetty, and that long period with a tiny swell won’t do much.
The far end of the window, July 27th and 28th, shows a pulse of S swell at 4ft to 4ft with 10-11 second periods. The energy is high (373-429), but the wind is a strong 25 km/h cross-shore, which will trash it. The morning of the 28th has a cleaner cross-offshore wind, but it’s still poor overall. It’s a long way out, so take it with a grain of salt.
The standout session is Monday, July 13th afternoon. That glassy 4ft groundswell is the only real gem in this whole 16-day forecast. Don’t miss it.
Rusty.

Information about the Big Ben Surf forecast
The above surf forecast table for Big Ben provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Big Ben can be found by selecting the local surf guide option on the grey menu. Our Big Ben 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 (Big Ben) 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 Big Ben 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.
Big Ben is 3 km (2 miles) from Kawaguchi. If you plan a holiday in Chiba, look for hotels and other accommodation in Kawaguchi. Kawaguchi has rooms for a wide range of budgets as well as car hire and transport links.
