Alright, this is Rusty, and I’ve got a pretty grim picture for Asakawa for the next couple of weeks. Honestly, for the first ten days, we’re looking at a real surf drought. There’s nothing worth paddling out for from Monday the 13th all the way through to Sunday the 26th of July. That’s a solid, frustrating stretch of tiny, weak, and messy conditions. Most days are a write-off with poor surf quality, and the few that show a small bump are still too ordinary to get excited about. The wind is mostly onshore or cross-onshore, and the swell is just too small and weak to do anything.

The one and only standout, the only real light at the end of the tunnel, comes on Monday the 27th of July. The morning session is the one to circle on your calendar. Asakawa will finally see a pulse of 4ft swell from the SSE, with a period of 11 seconds, giving it some decent energy. The combined swell energy hits 789 (moderate), and the wind is forecast to be glassy from the SE. That means clean, lined-up waves. The water is a bit colder than average for the time of year at 78°, but that’s a small price to pay for what looks like the best conditions in this whole outlook. The break is a point, so it should handle that SE groundswell well. Just keep in mind it’s inconsistent and crowds are sometimes a factor, so pick your bank and your moment.

By Monday afternoon, the swell is forecast to jump to 6ft, and the energy jumps to 1089, which is strong. But the wind swings onshore from the SE, and the tide or conditions might make it tricky. That’s more of a session for the experts, as 6ft is pushing it for beginners. The following Tuesday morning, the 28th, still has some 5ft swell from the SSE, but the wind is cross-shore, so it won’t be as clean as Monday morning.

So, to sum it up: the first ten days are a total write-off. Save your energy for Monday the 27th of July, morning session. That’s your best chance for a proper surf in this stretch.

Information about the Asakawa Surf forecast

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