The Lowdown
Alright folks, Rusty here. Let's have a look at what's cooking for the region.
Right off the bat, I gotta be straight with you – the next few days are a write-off. We're looking at a pretty grim run of weather and messy conditions. From Saturday the 5th through the middle of the week, it's a no-go. The water temp is sitting at a warm 84° here at Cape Toi, which is pretty much dead average for this time of year, so at least the water feels nice even if the waves are junk.
The first real glimmer of hope comes on Wednesday the 9th. The afternoon session looks like a sneaky little window. We've got a light breeze from the north at 6 mph, making for clean conditions, and a small 3 ft swell from the southeast. The combined energy is weak at 210, so don't expect a lot of power, but it's clean and rideable for a learner or someone with a log. It's a better option than the junk we've had.
Now, hold onto your board, because the real standout is shaping up for Monday the 15th. Tuesday morning the 15th is looking like the pick of the entire forecast. We've got clean conditions with a light northeast breeze at 6 mph, a chest-high 5 ft swell from the east, and a solid 10-second period pushing some decent energy – the combined energy is 659, which is moderate. This is a reef break, so that longer period groundswell is going to wrap in nicely and give us some proper shape. It's inconsistent, so you'll be waiting for the sets, but when they come, they'll be clean. Crowds are possible here, so keep an eye out.
The following morning, Wednesday the 16th, also has a clean look with a tiny 3 ft swell from the east and barely a whisper of wind from the west at 3 mph. It's a good morning for the longboard if you can get out there before the wind swings.
Beyond that, the second week looks a bit of a letdown. There's a few days of small, weak, and messy surf with the wind not playing ball. Not much to get excited about. The energy drops right off, with the combined energy readings falling into the double digits, so it's a flat spell to end the outlook.
Stay patient, keep an eye on the 15th, and don't bother paddling out until then.
Rusty.

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.
