The Lowdown

Alright, Rusty here. Let’s have a look at what’s shaping up for Asakawa.

First off, the water’s sitting at 83°, which is a touch warmer than normal for this time of year – nothing crazy, but you’ll notice it’s a bit more like bathwater than usual.

The next few days are pretty flat and quiet. We’ve got a tiny little swell hanging around, but it’s mostly small and weak. Monday morning the 27th sees a glassy 1 ft of SE swell, period around 14 seconds, but the energy is weak (172). It’s surfable, but just barely. Monday afternoon gets a bit messy with a light cross-onshore wind, so that’s not worth getting excited about.

Tuesday the 28th and Wednesday the 29th are similar – small, clean in the mornings with glassy conditions, but the swell is tiny and the energy is low (136, 86). You might get a few fun little waves if you’re desperate, but honestly, it’s more of a paddle-around session.

From Thursday the 30th right through to Sunday the 2nd of August, it’s a real lull. Swell drops to 1.0 ft to 1 ft, energy is in the dumps (38 to 72), and conditions are poor. There’s a gap of about four days here where there’s really nothing worth paddling out for.

Now, things start to change around Monday the 3rd of August. We get a pulse of ESE swell pushing 4 ft to 4 ft, with a long period of 15 seconds. The energy jumps up to 601 and then 1131, so there’s some proper grunt behind it. But the wind is a bit messy – cross-onshore in the morning, onshore in the afternoon – so it’s only marginal. Not the best, but it’s a sign of things to come.

Tuesday the 4th of August is where it gets interesting. Morning brings a clean, glassy 7 ft of ESE groundswell, period 17 seconds, and the energy is strong at 2573. This is excellent for experienced surfers – the waves will have real power and shape. The wind is glassy and the conditions are clean. This is a standout. The afternoon gets a bit onshore, but the morning session is the one to aim for.

Wednesday the 5th of August sees the swell building further – 8 ft in the morning, glassy, with 17-second period and energy at 3767. Again, excellent for experienced surfers. The morning is clean, the afternoon turns onshore. This is another standout morning.

Thursday the 6th of August is a cracker. 10 ft in the morning, 16-second period, but the wind is cross-offshore from the NNE at 6 mph, making for clean, lined-up waves. Energy is a massive 4717. The afternoon is even bigger at 12 ft, with a gentle cross-offshore breeze and energy at 6102. This is the best of the run for experienced surfers – big, powerful, and clean.

Friday the 7th of August gets huge. 15 ft in the morning, 18 ft in the afternoon, with a 17-18 second period. The energy is enormous (11809, 18074). But the wind is cross-shore to cross-onshore, so it’s going to be a bit lumpy. The swell is well over 8 ft, so this is expert-only territory. It’s impressive, but not the cleanest.

Saturday the 8th of August is where it gets too big. 31 ft to 34 ft, with a 19-second period, energy at 63118 and 84212. The swell is predicted to be too big for this break – it’s going to be a washing machine. Not for paddling, unless you’re a tow-in specialist.

Sunday the 9th of August is still massive, with 39 ft in the morning and 26 ft in the afternoon. The morning is cross-shore, the afternoon onshore. Still too big for standard surfing.

Monday the 10th of August sees the swell drop back to 10 ft, with a 10-second period and energy at 2220. The morning is glassy, so it’s clean and powerful – good for experienced surfers again.

The standout in this whole run is clearly the morning of Thursday the 6th of August. You’ve got 10 ft of ESE groundswell, a 16-second period, cross-offshore wind, and sky-high energy. It’s big, clean, and powerful. The mornings of Tuesday the 4th and Wednesday the 5th are also excellent, but the 6th takes the cake.

Asakawa is a point break, and with this long-period groundswell (over 15 seconds), it’s going to handle it well – points love that kind of energy. The swell direction is from the ESE, which matches the optimum swell direction from the SE, so it’s coming in nicely. Crowds are possible at Asakawa, so get there early for the good ones.

Alright, that’s the story. The first week is a write-off, but the second week has some serious firepower. Get ready.

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.
