The Lowdown
Alright, let’s talk about Asakawa. This is a point break that’s inconsistent, so you gotta be patient. Right now, the water’s sitting at 83°F, a touch warmer than usual for this time of year – feels nice.
The first few days are real quiet. Monday 27th July morning has tiny 1.3 ft waves from the SE with a 14-second period, and it’s glassy, but the energy is weak (172) – it’s surfable but nothing to get excited about. That afternoon and Tuesday morning stay small, with a bit of wind messing it up. Tuesday afternoon, Wednesday, Thursday, Friday, and Saturday all stay under 2 ft, with the energy dropping to as low as 30. Honestly, it’s a flat spell for a week. You’d be better off waiting.
Then things start to change. Sunday 2nd August morning sees a little 1 ft pulse from the ESE with a 16-second period, energy 101 – still weak, but the wind is cross-off and clean. Not enough to ride though. Sunday afternoon has a bit more energy (204) but onshore wind.
Monday 3rd August is where it gets interesting. The swell jumps to 3.9 ft ESE, period 16 seconds, energy 688 – moderate. The wind is cross-on, so it’s a bit bumpy, but the size is building. Tuesday 4th August morning pushes 7.9 ft ESE, 17-second period, energy 3299 – strong. The wind is light onshore, so it’s not perfect, but the power is there. That afternoon hits 8.2 ft, energy 4084, still cross-on
Short Range ForecastLight rain (total 8mm), mostly falling on Mon afternoon. Warm (max 33°C on Tue morning, min 27°C on Tue night). Wind will be generally light. | Days 4-6 Weather SummaryMostly dry. Warm (max 33°C on Thu morning, min 27°C on Thu night). Wind will be generally light. | ||||||||||||||||||||

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.
