The Lowdown
Right then, let's have a look at what's on the cards for Takegashima over the next couple of weeks. It's a bit of a mixed bag, so we'll need to pick our moments. This is a reef setup that needs an easterly direction to really work its magic, and we've got some solid swells lined up, but the wind is going to be the deciding factor.
We kick off with a bit of a wait. The surf is small and messy through the weekend and into the start of next week. There's a pulse of S swell on Thursday the 20th, but it's only around 3ft and pretty ordinary. The real story starts to build from Friday the 21st. That morning we've got a 5ft S swell with an 11-second period, and the winds go glassy. The combined energy is a moderate 568, which is a good sign. It's clean and should offer some fun waves, but the direction isn't ideal for the break. This could be a nice little session if you're keen for a paddle.
The standout, the one to really circle on the calendar, is Tuesday the 25th. The afternoon is looking prime. We've got a 5ft SE groundswell with a long 14-second period, and the wind is forecast to go glassy. This is proper stuff, with a combined energy reading of 952. The swell direction is bang on for the break's optimum, so expect some clean, well-shaped lines peeling off that reef. Thursday the 27th sees a big jump in size, with a 10ft SSE groundswell on Thursday afternoon, but it's going to be blown out by onshore winds. That's one for the experts only, and even then, the conditions will be tough.
After a few days of strong, lumpy, and blown-out conditions from the end of that week, the following Monday the 31st could be interesting. We're looking at an 12ft ESE swell but with cross-shore winds. It'll be big, but not clean. The standout in that second week might actually be Sunday the 30th. The morning shows a massive 16ft SE swell with a 15-second period, and the wind is cross-offshore. That's a huge amount of energy (11,006), and it will be much cleaner than the days before. This is serious, heavy reef surfing for the hardcore crew only. The water temperature is sitting around 83°F, which is pretty much spot on for this time of year, so a steamer won't be needed.
To be honest, with that size and the reef setup, if the wind doesn't play ball on the bigger days, the bay could be more interesting for the kite surfers than us paddle guys.

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