The Lowdown
Alright folks, Rusty here. Let’s talk about what’s coming up for the next couple of weeks.
This is a bit of a slow-burner for the most part. We’ve got a stretch of modest, workable swell followed by a pulse of heavy, oversized groundswell that’s only for the brave. The good news is there’s a couple of windows of exceptionally clean conditions if you pick your moments.
The only real standout on offer is Ambinanibe. It’s a consistent, intermediate-level break that’s exposed to the swell. The water temp is about average for this time of year, so nothing shocking there.
The first real action kicks off on Friday morning, August 21st. The swell is a modest 5 ft from the SSW with a 13-second period, and the combined energy is moderate (730). The wind is cross-shore and light, so it’s workable but nothing to write home about. The score is marginal, so it’s more of a warm-up session.
The weekend picks up a bit. On Saturday morning, August 22nd, the swell jumps to 7 ft from the SSW, but the period drops to 15 seconds and the energy gets strong (1873). The wind is cross-onshore, making it a bit bumpy. The surf quality is still just marginal.
Sunday, August 23rd morning is the first real highlight. The swell drops to a clean 6 ft from the SSW, 13-second period, with moderate energy (1194). The wind is cross-offshore and light, giving us clean, organized waves. The quality is described as excellent for experienced surfers. This is your best bet for the first week.
After that, the week gets messy. Monday, August 24th, is a write-off with poor surf and cross-onshore wind. Tuesday morning, August 25th, is interesting though. The swell is 5 ft from the SSW, and the wind is glassy. That’s a major positive. The combined energy is moderate (886), and the conditions are expected to be very good. That morning session will be clean and smooth.
The surf picks up size again on Wednesday, August 26th, with 7 ft to 7 ft from the SSW, but the wind isn’t cooperating, and it’s just marginal.
Now, here’s the big one. Thursday, August 27th, is not for the faint of heart. The swell explodes to 10 ft to 13 ft from the S, with a very long period of 17 to 19 seconds. The combined energy is massive (6763 to 9503). This is a serious, powerful groundswell. The wind is glassy on the morning of the 27th, but the swell is too big for this break. This is heavy, expert-only territory. The setup looks more interesting for kite surfing than paddle surfing if you’re not a seasoned charger.
The swell slowly drops through the end of August and into the first week of September. Friday, August 28th, is still a huge 12 ft to 10 ft from the S, but with a strong cross-shore wind. Still too big for most.
By Saturday, August 29th, the swell is dropping to a more manageable 7 ft to 6 ft from the S, but the wind is a fresh cross-offshore. The period is dropping too, so it’s not as clean as the earlier pulses.
After that, the second week fades out. From Sunday, August 30th, into early September, the swell is small, 4 ft and below, with poor conditions. There’s a gap of several days where the surf is too small or just poor. There’s a tiny whisper of a 3 ft swell on Friday morning, September 4th, but it’s accompanied by a strong cross-shore wind, so it’s not worth the paddle.
So, to sum it up: your best bet is Sunday morning, August 23rd, for clean, fun waves. Tuesday morning, August 25th, is also a solid pick for glassy conditions. The big swell on the 27th and 28th is a spectacle for the experts, but the rest of the period is a slow fade. Keep an eye on the forecasts, though, because it tends not to stay poor for long.
Rusty.
