The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ at Okuragahama over the next couple of weeks.
Right off the bat, we’ve got a pretty flat spell to start. Friday the 31st of July and Saturday the 1st of August are only offering up tiny, weak little waves around 1.0ft to 1ft from the SE with a short period. The water’s a touch warmer than normal at 85°, about average for the time of year, but honestly, it’s not worth paddling out for. You’re looking at a couple of days of nothing.
Then Sunday morning the 2nd of August, things start to get interesting. The swell jumps to 2ft from the ESE with a super long period of 16 seconds and glassy conditions. This is a long-period groundswell with a combined energy of 238 (moderate), so it’ll have some punch but might be a bit straight at the beach – but Okuragahama is a point break, so it’ll wrap in nicely. This is a solid little session for a log or a fish.
The real standout window, though, is Monday the 3rd through Wednesday the 5th of August. Monday morning we’ve got 5ft from the ESE, period 16 seconds, and a cross-offshore wind – clean and lined up. The combined energy jumps to 1207 (strong). That’s a proper groundswell. By Wednesday afternoon the 5th, we’re looking at 18ft from the ESE with an 18-second period and a combined energy of 19664 (very strong). The wind is cross-shore, and the report says the swell is predicted to be too big for this break. That’s strictly for the big-wave chargers, and honestly, only experts should even think about it. If you’re a beginner, stay well clear – that’s over 8ft.
From Thursday the 6th through to the 9th, it gets messy. The swell is huge (up to 30ft), but the wind turns strong cross-onshore and stormy, with risk of thunderstorms. The combined energy is through the roof (over 56593), but it’s going to be a ragged, lumpy mess. Not great for a clean paddle session, but if you’ve got a kite, this setup might be more your speed.
After that, the week of the 10th to the 15th sees a drop in size. Tuesday morning the 11th of August is a nice pick: 5ft from the E with a 13-second period, glassy conditions, and a combined energy of 1057 (strong). That’s clean, manageable, and should be a good paddle for intermediates. If you can get out on the Thursday morning the 13th or Friday the 14th, you’ll find clean 3ft to 5ft waves with a light offshore cross-off breeze. The crowds at Okuragahama are listed as “often”, so don’t expect to have it to yourself.
So, the standout days are Sunday morning the 2nd for the glassy start, and Tuesday morning the 11th for the clean, mid-sized groundswell. The mid-week monster from the 5th is for the brave and the expert only.
Rusty.

Information about the Okuragahama Surf forecast
The above surf forecast table for Okuragahama provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Okuragahama can be found by selecting the local surf guide option on the grey menu. Our Okuragahama 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 (Okuragahama) 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 Okuragahama 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.
Okuragahama is 22 km (14 miles) from Nobeoka. If you plan a holiday in Kyu Shu, look for hotels and other accommodation in Nobeoka. Nobeoka has rooms for a wide range of budgets as well as car hire and transport links.
