Table - best surf conditions forecast for Big Ben over the next 16 days.
Alright, mate. Rusty here, letting you know what’s cooking for Big Ben. This little beach/jetty spot is about to see some action, but it’s a bit of a mixed bag over the next couple of weeks. The water’s sitting at 75°, which is about average for the time of year, so no surprises there.
The big news is the weekend ahead. We’ve got a solid, long-period SSW groundswell rolling in, and the combined wave energy is pumping hard at 3435. Saturday morning sees a solid 8ft swell from the SSW, but the wind is cross-shore out of the SW at 9 mph, so it’s going to be a little lumpy and not the cleanest. Still, that’s a lot of water moving, but this spot is inconsistent, so you’ll need patience. Saturday afternoon gets blown out further with cross-onshore winds, so don’t bother.
Now, the standout window. Monday morning, July 13, is your real target. The swell has dropped to a much more manageable 5ft from the SSW, but look at the conditions: a light NE wind at 3 mph, cross-offshore, and the forecast is calling for clean surf. This is the best combo of size and glassy conditions you’ll see. The wave energy is still moderate at 681, and the period is a very long 13 seconds, so those waves will have some serious push and shape. For a beach/jetty setup, that long period might make things a little straight, but with that offshore wind, it should be worth the paddle.
Monday afternoon turns glassy with a 4ft swell and 493 energy. If you can sneak away for a session, it’ll be smooth. Tuesday morning, July 14, is also glassy, but the swell is down to 3ft, so it’s getting smaller.
After that, things go flat and poor. From Wednesday, July 15, right through to Tuesday, July 22, the surf quality is poor, with small weak swells and choppy conditions. There’s a 6-day gap where you’re better off doing something else.
Then we get a flicker of hope for Wednesday morning, July 22. A new ESE swell shows up at 8ft, with a period of 13 seconds, combined energy of 2071, and clean conditions with a cross-offshore NNE wind at 16 mph. That’s a lot of juice, but at that size and direction on a beach/jetty, it’s for experienced surfers only. The period is long, so expect long lulls between sets, but the shape will be good. Thursday morning, July 23, sees a drop to 5ft from the SE, still clean, with 931 energy, which could be a more fun, less hectic wave.
For the rest of the second week, the wind stays strong and the conditions are messy. Another pulse on Saturday, July 25, is only 3ft and the energy is weak at 318, not worth a trip.
The pick of the fortnight is Monday morning, July 13. That 5ft SSW swell with clean, cross-offshore winds and a nice long period is the best you’re going to get. Crowds are possible, so get in early.

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.
