Alright, Rusty here. Let’s have a look at what’s cookin’ for Big Ben.
Right off the bat, I gotta be straight with ya – the next few days are pretty flat and ordinary. We’ve got a real slow start with barely any swell to speak of and messy wind. Friday the 3rd and Saturday the 4th are not worth paddling out for. The swell is tiny, around 2ft to 3ft, and the wind is all wrong – cross-on or onshore. It’s a write-off.
Sunday the 5th through Monday the 6th isn’t much better. Still small, still choppy. You’re lookin’ at a solid gap of nothing good until we get to Tuesday the 7th. That’s when things finally start to change.
Now, Tuesday morning the 7th, a proper long-period groundswell starts to roll in from the SE. We’re talkin’ 7ft at 16 seconds – that’s serious energy (2840). The wind is light and cross-offshore from the E, so the conditions are clean. This is the first real window for a surf, but that swell size is getting up there, so it’s more for intermediate to advanced surfers. Beginners might find it a handful. The combined energy is moderate-to-strong.
Wednesday the 8th is the standout, but there’s a catch. The morning sees a solid 10ft SE groundswell at 16 seconds – huge energy (5530) – and the wind is light and straight offshore from the SE. That’s a recipe for some epic, clean waves if you’re an expert. But honestly, the wave comment says it’s predicted to be too big for this break. If you’re not a charger, sit this one out. The afternoon drops to 8ft but stays clean.
Thursday the 9th keeps the size up, 8ft to 10ft from the S, but the wind swings around to a moderate SSW cross-shore. It’s still big and powerful, but the conditions will have a bit of a chop on ‘em. Again, experts only.
Friday the 10th is the real gem for the crew who can handle it. We’ve got a 10ft S swell at a very long 17 seconds (6156 energy) and a light offshore from the WSW. The morning is glassy and clean. That’s about as good as it gets for the big stuff. But remember, it’s still a big swell – definitely not for the faint of heart.
After that, the swell slowly drops through the second week, from 8ft down to about 3ft by Monday the 13th, with mostly cross or onshore winds. There are some surfable waves in there, like Saturday the 11th morning with a clean 8ft SSW swell (3268) and a light offshore, but nothing compares to that Wednesday-to-Friday window.
From the 14th onward, it’s back to small, weak, and poor. The water temp is about average for this time of year – nothing unusual. Big Ben is inconsistent, so this run of small surf isn’t surprising. Crowds are possible, but honestly, with this forecast, it’ll be quiet.
The one true standout is Wednesday morning the 8th and Friday morning the 10th for expert surfers only. For the rest of us, Tuesday the 7th morning is the best bet for a manageable, clean wave.
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.
