Alright folks, Rusty here. Let’s take a look at what Big Ben’s got cooking for us over the next couple of weeks. It’s going to be a slow burner, but there’s a gem waiting for the patient ones.

First up, the water temps are sitting at 73°, which is a bit colder than normal for this time of the year – you’ll want a decent spring suit.

Right off the bat, we’ve got nothing happening. The first few days are a write-off. Monday the 6th is choppy and messy with a weak 2ft cross-on shore SE swell, but the wave energy is moderate (425). It’s just poor out there. Tuesday the 7th isn’t much better, a bit more push but still ugly wind. Basically, the start of the week is a total loss.

We finally see some life building through the middle of the week, but it’s accompanied by a constant cross-onshore breeze. Wednesday the 8th and Thursday the 9th bring a solid 7ft SSE groundswell with a very long period of 16 seconds, so there’s plenty of energy in the water (3427). The problem is the wind keeps things from getting truly clean. It’s *rideable* for the more experienced crew, but beginners will be out of their depth with size over 7ft. The long period also means it might close out a bit at this beach/jetty setup.

Friday the 10th and Saturday the 11th hold that size, with a peak of 8ft on Saturday morning from the SSW, still with that very long 17-second period. The wave energy is strong (3871). But again, the cross-onshore wind is the story here – it’s keeping the surface bumpy. This is one of those stretches where the power is there, but the quality is only marginal.

Things fade fast. Sunday the 12th through to the 20th of July is a really poor run. The swell drops, the wind is a mess, and you’re looking at a long stretch of days with no real recommendations. It’s a blank period.

Now, for the standout. If you’ve got the patience, mark your calendar for Tuesday, July 21st. This is the one that matters. We’ve got a 8ft E swell pushing in, but the big news is the wind. On Tuesday morning the wind turns cross-offshore and light – that’s the key. For the first time in the forecast, the conditions are described as clean. The wave energy is very strong (2398) and the swell matches the optimum direction. This is excellent surf for experienced surfers – that size and clean face is a proper session. It will be an early call, and being over a week out it’s a promising prospect, but this is the window you want.

After that, it looks like the wind messes it up again in the afternoon.

So, the long and short of it: forget the first week, sit tight through the garbage, and keep your eyes locked on the 21st.

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.
