The Lowdown
G’day, Rusty here. Look, I’ll be straight with you – this 16-day window for the local stretch is a bit of a dud. We’ve got a solid run of nothing worth paddling out for, so don’t be in a rush to wax the board.
The first sign of any surf comes in on Wednesday, 15 July, but it’s not worth a look. Asakawa (point) is showing a tiny 2ft SSW swell with a period of 9 seconds, and a combined energy of just 130 (weak). The wind is a light cross-shore, but the conditions are rated as poor. It’s inconsistent here, and that’s the story for nearly the whole forecast.
The gap stretches from the start all the way through to the end of the first week. There’s a small window on Thursday, 16 July, morning – the swell is a meagre 3ft from the SSW, period 8 seconds, energy 131 (weak), but the wind goes glassy, so it’s clean. However, the forecast says “surfable waves but very ordinary conditions,” so it’s barely a paddle. The water temp is 78°, which is a bit colder than normal for this time of year.
Honestly, there’s nothing to recommend. The swell stays tiny – under 2ft – for days on end, with weak energy and mostly onshore or cross-onshore winds. The only flicker of something different comes on Saturday, 25 July, which is over a week away. The morning sees a 1ft swell from the SE, but the period jumps to 16 seconds, and the energy is 211 (moderate). The wind is glassy, and it’s clean. But the swell is so small and the period is long, so at a point break like this, it might just be a few straight lines. It’s still “surfable waves but very ordinary conditions.”
The following week stays poor – the energy gets up to 294 (moderate) and 262 (moderate) on the 25th and 27th, but the swell is still under 3ft, the wind is rubbish, and the conditions are consistently poor. For a beach break setup, this would be more interesting for a kite surfer than a paddle surfer, but here it’s a point, so it’s just flat and messy.
Overall, there’s no standout. The inconsistency of the break means this blank run is normal for the area. Keep an eye on it, but for now, stay home.
Rusty.

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.
