Right then, Rusty here. Let’s have a look at what the next couple of weeks are serving up for Big Ben (beach/jetty).
We’re kicking off with some proper sized swell rolling in, but it’s going to be a bit of a battle with the wind for a few days. The water temperature is sittin’ at 74°, which is a bit colder than normal for this time of year – about 2° cooler, so you’ll feel that nip when you’re paddling out.
The best of the action, and the standout for me, is Monday the 13th of July. We’ve got a drop in size to a clean 4ft from the SW, and the wind goes glassy or light offshore. That’s when Big Ben will offer up its best shape, with clean conditions. The combined wave energy is moderate (541–577), so there’s enough push for a fun session on a longboard or mid-length. Just bear in mind this break can be inconsistent, and because it’s exposed to the swell and crowds are sometimes around, you might have to wait for the sets, but the quality will be worth it.
Leading up to that, from Tuesday the 7th of July, we’ve got solid swell – 6ft to 8ft from the SE and SSE – with moderate combined energy in the thousands (1569–3561). Problem is, the wind is cross-onshore or cross, making it fairly choppy. As the swell gets over 8ft on Saturday the 11th and Sunday the 12th, it becomes one for experienced surfers only, and with the choppy cross-shore wind, it’s going to be a messy affair. The period is long (14–17 seconds), which is groundswell, and at a beach/jetty setup, that long period can make waves break a bit straight, so it’s not ideal.
After Monday’s gem, the swell drops right off. Tuesday the 14th and beyond sees tiny, weak swell under 3ft, with combined energy dropping below 400. Winds turn cross or onshore again, and conditions are poor. There’s a long gap from the 14th right through until the end of the window, with only small, glassy dribbles on the 19th and 20th of July – that’s less than 2ft from the east, and not really worth getting wet for unless you’re desperate for a paddle.
So, in short: Monday the 13th of July is your day. The rest is either blown out or too small to get excited about.

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.
