The Lowdown
Alright, Rusty here, let’s talk about what’s on offer for the next couple of weeks.
First off, I’ve only got one spot to work with, and that's Big Ben. It's a beach/jetty setup, and it's inconsistent. For the first few days, there’s really nothing to get excited about. Sunday the 26th and Monday the 27th have some small, weak energy, but it’s not coming together. The water temp is sitting at 80°F, which is about normal for this time of year, so no surprises there.
The real story is that after a long, flat spell, the ocean starts to fire up, but it gets way too big for this break. The first real standout is Friday morning, 31 July. The swell is a clean 4ft from the SW, with a short period of 6 seconds, and the wind is cross-off. The combined energy is moderate (203). It’s the best bet for a beginner-friendly wave in the near term, but keep in mind, the spot is inconsistent, so it’s a bit of a roll of the dice.
Then, from the 2nd of August onwards, the swell gets huge. We’re talking 10ft to 23ft from the ESE and SE, with very long periods of 16 to 17 seconds. The combined energy is massive (1868 to 42447). This is a *very* strong, powerful groundswell. For a beach/jetty break, that long period will make the waves break too straight and dumpy, not to mention the size is only for expert surfers. The wind is cross or cross-off, which is good, but the sheer size makes it a no-go for anyone but the most experienced. The forecast for the 4th of August and beyond says it all: "too big for this break."
So, if you’re a beginner, you’re looking at Friday morning, 31 July. If you’re an expert, the 3rd to the 10th of August has colossal swell, but it’s too dangerous and messy for paddle surfing at this spot – honestly, it looks more interesting for kite surfing. There’s a gap of several days of nothing before the big stuff hits, and then it’s just too much.
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.
