Asakawa Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s have a look at what’s cooking for Asakawa over the next couple of weeks.

We’re starting off with a bit of a slow warm-up, but there’s some serious firepower on the horizon. The first few days are small and clean but nothing to get too excited about. The real standout is going to be a massive pulse of groundswell that arrives in the middle of the second week, but it’s a double-edged sword—you’ll need to pick your moment or it’ll be a washing machine.

Sunday, August 2nd kicks things off with a tiny, clean 2ft ESE swell. The combined energy is weak (349), so it’s more of a longboard or foiling kind of day. Morning glass is nice, but it’s not going to get the heart racing.

Monday, August 3rd sees the swell building to 5ft with the same ESE direction, but the wind gets messy in the afternoon with a risk of thunderstorms and cross-onshore chop. The energy jumps to 1198 (moderate), but conditions are ordinary.

Tuesday, August 4th is a real tease. The morning is glassy with a 10ft ESE swell, and the combined energy is cranking at 5629 (strong). That’s excellent surf for experienced surfers if you can handle the size. The period is 17 seconds, which is very long period groundswell—this will be lining up beautifully at Asakawa point, but the wait between sets will be long. The afternoon turns onshore and messy, so the morning is the only window.

Wednesday, August 5th gets huge. The swell hits 15ft to 16ft from the SE, with combined energy screaming up to 12900 and 15802 (very strong). This is expert-only territory, and the wind is cross-shore, so it’s going to be a raw, powerful grind. Only for the brave.

Thursday, August 6th peaks at a massive 20ft swell. The morning has 21936 (very strong) energy, but the wind is a moderate cross-shore chop. The forecast literally says it’s too big for this break. The afternoon gets even worse with onshore winds. This is a day to watch from the cliff, not paddle out.

Friday, August 7th the swell drops to 16ft, still huge. The morning has cross-off wind but the energy is still 12900 (very strong). Afternoon gets messy again. Not a beginner’s day.

From Saturday, August 8th through to Monday, August 10th, the swell fades steadily from 12ft down to 5ft, but the wind is mostly cross or cross-onshore, and the energy drops from 6675 (moderate) down to 1084 (weak). The surf is marginal and choppy. A bit of a down period.

Tuesday, August 11th morning is a hidden gem. The swell is only 4ft from the S, but it’s glassy with a light SSW wind. The energy is 682 (weak), but the conditions are clean and the period is 12 seconds—a solid, fun wave for the intermediate surfer.

Wednesday, August 12th and Thursday, August 13th are very small and ordinary. Swell around 2ft to 3ft, energy under 250 (weak). Not worth rushing out for.

Now, Friday, August 14th is the next real highlight. The morning brings a glassy 7ft ESE swell with a 11-second period, and combined energy of 1007 (moderate). The afternoon is dead calm, glassy as a mirror, with 6ft swell. This is beautiful, clean, head-high-ish surf at Asakawa.

Saturday, August 15th morning keeps it going with a clean 7ft ESE swell, cross-off wind, and energy of 1042 (moderate). The afternoon turns onshore and messy, so the morning is the pick.

Sunday, August 16th is a bit of a mixed bag. The swell is 10ft from the E with a short 9-second period, so it’s lumpy and less organized. The wind is cross-shore. Energy is 2644 (moderate), but it’s not the cleanest.

Monday, August 17th finishes the forecast on a high note. The morning is clean with a 8ft E swell, 11-second period, and cross-off wind. The energy is 2088 (strong), and the conditions are rated excellent for experienced surfers.

Best on offer: The standout is undeniably Tuesday, August 4th morning – that 10ft, 17-second groundswell with glassy conditions is a serious session for the experienced crew. The second best is Friday, August 14th – both morning and afternoon offer clean, user-friendly waves. The long period groundswell at Asakawa point will bend beautifully, but the sets will be spaced out, so be patient.

Crowds at Asakawa are possible, especially on the standout days when the conditions are clean. The water temperature is about average for this time of year, nothing unusual.
