The Lowdown
Alright, let’s talk about Big Ben. It’s a beach/jetty setup that’s exposed but inconsistent, and it doesn’t always fire. The next 16 days are a bit of a mixed bag – we’ve got one clear window of clean surf, then a whole lot of nothing special. The water temp is sitting at 77°F with a near‑normal anomaly, so nothing wild there.
The only real standout in this entire forecast lands on Tuesday morning, July 14. We’ve got a 3‑ft SSW swell rolling in with an 11‑second period – that’s a decent groundswell, but it’s coming from a direction that’s not the best for Big Ben (optimum is SE). Still, the wind is glassy out of the SSE at 3 mph, so the surface will be clean and smooth. The combined energy is moderate at 240, and with that light wind, it’s your best shot. After that, the afternoon turns cross‑shore and the swell drops a bit, so that morning is the one to hit.
From Tuesday afternoon all the way through the rest of the forecast, conditions go downhill fast. Winds shift onshore or cross‑onshore, swells stay small (mostly 2 to 4 ft), and the energy never really gets strong. There are a few mornings with marginal conditions – like Thursday July 16 with a clean cross‑offshore wind and 2 ft, or Friday July 17 with 4 ft but cross‑shore winds – but none of them are worth getting excited about. The inconsistency of the break means you’d be gambling on a lucky set.
The second week doesn’t bring any relief either. From July 20 onward, we see a few days with 3 to 4 ft swell, but the wind is always cross‑shore or onshore, and the periods are short (8–10 seconds). The energy stays moderate (100–350 range). Then on July 27 and 28, we get some longer‑period SSE swell (11–13 seconds), but the wind is straight onshore, so it’s choppy and messy. The last day, July 29, actually has a very long 19‑second groundswell coming from the ESE with combined energy of 593 – that’s a solid pulse. But the wind is cross‑onshore at 12 mph, so it’ll be blown out. For a beach break, that long period tends to make the waves close out anyway, and with the wind, it’s not a goer.
So, to put it simply: Tuesday morning, July 14, is your best bet. After that, you’re looking at a long stretch of mediocrity. The crowds are listed as “sometimes”, so you might have a few others out, but with the conditions, it’ll be quiet. Keep an eye on the wind forecasts – if anything changes, there could be a surprise, but as it stands, it’s a one‑day show.

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.
