Alright, Rusty here, let's see what we've got for Big Ben over the next couple of weeks.
We're in for a bit of a slow start, so don't rush out there just yet. The first few days are a write-off, with tiny, gutless swell and a cross-onshore breeze that'll just chop everything up. You're looking at waves under 3 feet and weak energy, honestly, it's not worth wetting a suit for.
The real story starts building on Tuesday, July 7th. We've got a big groundswell pulse arriving from the SE, with wave heights climbing to 7 ft and a very long period of 16 seconds. The combined swell energy is serious, clocking in at (3109). Tuesday morning looks your best bet early on, with a clean cross-offshore wind from the NNE blowing at 15 mph. That's gonna groom the faces nicely. Just be aware, this is a long-period groundswell which can be a bit tricky at beach breaks, making them close out. Keep an eye on it.
Wednesday the 8th sees the swell build even more, hitting 8 ft from the SSE, still with that super-long 16-second period. But the wind swings onshore from the E, making things a bit lumpy. The energy is huge though (4861), so if you're an experienced surfer looking for a challenge, it's there.
The standout, and I mean the real standout, is Friday morning, July 10th. The swell is still a solid 8 ft from the S, period at 16 seconds, and combined energy is massive (3335). But the magic is the wind: it's totally glassy, zero wind, for that classic clean, smooth surface. This is the morning for the crew who know what they're doing. Anything over 8 ft like this is expert territory, but if you've got the skill, this is the session of the forecast period.
The surf hangs in for the weekend, with waves around 6 ft to 8 ft, but the wind gets a bit messy. By Sunday, July 12th, the swell is dropping, but you'll find some glassy windows, especially Sunday afternoon with a tiny 3 mph NE wind. The energy is still decent (1622).
After that, it fades. The second week drops off fast, with a few small, glassy mornings on the 13th and 14th that are surfable but very ordinary. A little flare-up of weak windswell on July 18th might give you something waist-high, but it's nothing to get excited about.
So to sum it up: the first week is a no-go until Tuesday, July 7th. The best windows are the clean, offshore Tuesday morning, and that pristine, glassy Friday morning on the 10th. After that, it's small and inconsistent.
Stay safe, and I'll see you out there.

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.
