The Lowdown
Alright, this is Rusty, and I’ve got a look at the Cape Toi region for you. Let me break it down.
Right off the bat, folks, it’s a rough start. We’re looking at a solid stretch of poor conditions for the first week. From Sunday, August 30th, all the way through the first part of September, the wind is a problem. It’s coming mostly from the south and east, creating cross-onshore and onshore junk. The swell is small, weak, and the combined energy is low, barely cracking 100 on the best of those days. Water temp is sitting at a warm 84°, which is about normal for this time of year, so at least a dip in the water won’t be a shock.
We do see a bit of a bump on Wednesday, September 2nd, with a short-period SE swell pushing 6ft, but the energy is only moderate and the wind is a messy cross-onshore with thunderstorms likely. That’s not one to get excited about for a paddle. On the 6th of September, there’s a big spike in energy on Sunday morning with a 6ft ESE swell and a long 14-second period, but the wind is a fresh 19 mph cross-shore. That’s more of a kite day than a surf day at Cape Toi.
The real light at the end of the tunnel, and the standout in this entire forecast, lands on Thursday, September 10th. The morning is looking clean. We’ve got a solid 8ft swell from the ESE with a 12-second period, and the wind is a light cross-offshore from the NE. The combined energy is strong. This is excellent surf for experienced surfers, but at that size, it’s too much for beginners. The wave comment says it’s clean, and with that light breeze, it’s going to be a session to remember. The afternoon on the same day is still good, but the wind turns a little cross-on, so the morning is the window.
Then, on Saturday, September 12th, we get another cracker. The morning is glassy. A 10ft ESE swell with a 9-second period and no wind. That’s pure, lined-up power for the experienced crew. The energy is very strong. That’s a big day, and it’s going to be a standout.
After that, the swell drops off into tiny, weak waves again for the second week. A few glassy mornings with knee-high chops, but nothing to write home about.
So, to sum it up: the first week is a write-off. The two sessions to circle are the morning of Thursday, September 10th, and the morning of Saturday, September 12th. Both are for the experienced surfer, but they are the best on offer. Cape Toi is inconsistent, so when it fires, you gotta be there. But remember, long-range forecasts are promising, not a guarantee.
Stay patient, and keep an eye on the sky.

Information about the Cape Toi Surf forecast
The above surf forecast table for Cape Toi provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Cape Toi can be found by selecting the local surf guide option on the grey menu. Our Cape Toi 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 (Cape Toi) 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 Cape Toi 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.
Cape Toi is 15 km (9 miles) from Kushima. If you plan a holiday in Kyu Shu, look for hotels and other accommodation in Kushima. Kushima has rooms for a wide range of budgets as well as car hire and transport links.
