Asakawa Surf Forecast and Surf Report

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

Right off the bat, we’ve got a bit of a slow start. The first proper surf we see kicks off on Tuesday, the 8th of September. It’s not massive, but there’s a solid S swell rolling in at 4ft to 5ft with a 9-second period. The wind is a light cross-offshore from the NE, so it’ll be clean. The combined energy is moderate (509-623). It’s surfable, but nothing to write home about. A solid warm-up.

Now, the real standout of the first week is Wednesday, the 9th of September. We’ve got a building swell from the SSE, and by morning it’s already 8ft, pushing 10ft by the afternoon. The period drops to 8 seconds, but it’s glassy—dead flat wind from the SSE. The energy jumps big time (1915-1994). This is for experienced surfers only; it’s going to be a bit of a beast. If you’re not comfortable in solid overhead surf, sit this one out. The water temperature is about average for the time of year.

Thursday and Friday (10th & 11th) see the swell drop back, but it stays clean. Thursday has 4ft from the SSE with a cross-off wind, just ordinary. Friday morning is glassy but small at 3ft. The energy is weak (208). Not a priority.

The weekend (12th-13th) is a write-off. The swell fades to under 2ft, and we get poor conditions with onshore or cross-onshore winds. Small and choppy. There’s a gap of a few days here with nothing worth chasing.

Monday, the 14th of September, offers a little flicker. A 4ft SE swell with a 9-10 second period, glassy, and clean. Energy is moderate (245-272). It’s surfable, but not a standout.

The middle of the week is a bit of a mess. Tuesday (15th) has poor conditions with onshore winds. Wednesday (16th) is small and clean but unexciting. Thursday (17th) is a write-off with strong 12 mph winds and tiny surf. Don’t bother.

Now, hold on to your board, because the second week comes alive.

Saturday, the 19th of September, sees a punchy 8ft ESE swell with a short 7-second period. The wind is a light cross-off from the NE, so it’s clean. The energy is strong (699). This is very good, but the short period means it’ll be a bit bumpy. Best for those who like a bit of push.

Sunday, the 20th of September, is a beauty. A solid 7ft to 6ft E swell, still short period (8 seconds), but glassy calm wind. The energy is high (1028-1092). This is clean, strong, and very surfable. This is a top pick for the week.

But the absolute highlight of the whole forecast is from Monday, the 21st of September, through Wednesday, the 23rd. We get a long-period groundswell from the SE with a remarkable 16-second period. The swell size is 7ft on Monday, building to 10ft by Tuesday and Wednesday. The energy is enormous (2703-4961). This is a serious, powerful swell. The wind stays light cross-off from the NNE or NE, so it’ll be clean.

This is expert territory. At 10ft with a 16-second period, it’s going to be a heavy, straight wall at a beach break, so this is a spot where a point or reef setup would be ideal. The energy is massive. If you are an experienced surfer, this is the window. The best is on Tuesday and Wednesday, the 22nd and 23rd of September. Mark it.
