The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s cookin’ for Kamakura over the next couple of weeks.

To be straight with you, the first few days are a bit of a write-off. We’re looking at weak, short-period windswell and mostly onshore or cross-onshore breezes, so the surf is pretty ordinary. The water temp is sitting at about 82°, which is a touch warmer than normal for this time of year, so you won’t need a thick wetsuit.

Things start to get interesting around Sunday the 2nd of August. We’ve got a longer period swell showing up, around 16 seconds, coming from the ESE. The energy picks up to a moderate 118 (combined energy), and the wind is cross-offshore in the morning, making conditions clean. The swell is still small, only about 1ft, so it’s not going to be a standout, but the shape should be better with that long period.

The real action starts to build from Monday the 3rd. The swell starts to climb, and by Tuesday the 4th, we’ve got 6ft to 6ft from the SE, with a very long period of 17 seconds. The combined energy is strong, hitting 1643 and then 2071. The wind is cross-offshore, so the waves will be clean. This is getting into intermediate territory, but the long period will make the waves more powerful and lined up, with longer waits between sets.

Now, the standout – and I mean the real standout – is Wednesday the 5th and Thursday the 6th of August. The swell is predicted to be a solid 10ft from the SSE and S, with a 17-second period. The energy is huge, peaking at 5718 (combined energy). The wind is light and cross-offshore, making for what could be some epic, clean conditions. However, this is a big one. At 10ft, this is for experts only. It’s going to be powerful and heavy, and the long period means it might be a bit too straight for the beachbreak, but if you’re a seasoned charger, this is your window.

After that, the swell drops off quickly. By Saturday the 8th, we’re back to 4ft, and the following week is dominated by small, weak swell and strong offshore winds. The wind is strong offshore from the north from the 11th onwards, which is clean, but the swell is tiny, around 1ft to 2ft. The energy is weak, under 100 (combined energy). It’s a frustrating stretch – the wind is right, but there’s just no power in the water. For a few days there, it’ll be a blank run of no real surf.

So, to wrap it up: if you’re an expert, circle Wednesday the 5th and Thursday the 6th on your calendar. That’s the best on offer. For everyone else, keep an eye on Tuesday the 4th for some solid, clean waves, or the small but clean windows on the 2nd and 8th.

Rusty.

Information about the Kamakura Surf forecast

The above surf forecast table for Kamakura provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kamakura can be found by selecting the local surf guide option on the grey menu. Our Kamakura 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 (Kamakura) 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 Kamakura 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.

Kamakura is 2 km (1 miles) from the city of Kamakura. If you plan a holiday in Kanagawa, look for hotels and other accommodation in Kamakura. Kamakura has rooms for a wide range of budgets as well as car hire and transport links.
