The Lowdown
Alright, mate, Rusty here. Let's have a look at what Kamakura's got cookin'.
Right off the bat, it's a tough stretch. For the first week or so, we're lookin' at a real flat spell. From Saturday the 18th right through to Sunday the 26th of July, there's hardly a ripple worth paddling for. Swell heights are barely nudging 1 foot, with weak, short-period wind slop. The combined energy is pitiful, mostly in the teens and 20s – that's weak stuff. Winds are mostly onshore or cross-onshore, keeping the surface messy. Even the glassy moments on the 22nd and 25th mornings are wasted on waves that are just too small to ride. It's a solid 9-day drought of surf.
Now, things try to change as we head into the last week of July. On Monday the 27th of July, we start to see a pulse of energy. By Tuesday the 28th of July, the swell really jacks up. We're lookin' at a 10-foot SSE groundswell with a long 14-second period, and the combined energy is rippin' at 2046 (moderate-strong). The wind on Tuesday morning is a light 6 mph from the south – onshore, but light. The afternoon sees it jump to 12 mph. The problem is, the wave comment says it all: "swell is predicted to be too big for this break." At 10 feet, that's expert-only territory, and Kamakura's a beginner spot. The conditions might be "wind and tide favorable," but the size is just a monster for this beach.
It stays huge through Wednesday the 29th, Thursday the 30th, and Friday the 31st of July, with swell hanging around 10 to 12 feet from the S and SSE. Periods are long, between 13 and 16 seconds, suggesting powerful groundswell. The combined energy peaks at 5559 and even 6409 (strong to very strong). But the same story repeats: too big. Add in onshore winds and even a risk of thunderstorms, and it's just not user-friendly for the crew at Kamakura. The only real highlight in the whole 16 days is Tuesday the 28th of July, but only if you are an expert surfer comfortable in heavy, powerful surf. For everyone else, it's a hard pass.
Water temp is sittin' around 78°F, with a tiny anomaly of +0.4°F, so pretty average for the time of year.
Honestly, this setup looks more interesting for kite surfing than paddle surfing for the majority of the window, with those strong onshore winds and big, messy swell.
This is Rusty, signing off.

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.
