The Lowdown
Alright, let’s get into it, mate. The next few days are a bit slow, but once we hit the middle of the week, we’ve got a solid run of groundswell coming in from the south-west, and the wind is looking good for most of it. The water’s sitting at a warm 76.1°, which is a touch warmer than normal for this time of year, so you won’t need a thick wetsuit.
First up, Wednesday morning the 2nd of September at Riviere Noire Harbour. It’s a sandbar setup, fairly exposed to the swell, and it’s breaking with a clean 3.3 ft from the south-east. The wind is off the east at 12 mph, so it’s moderate offshore and clean. The combined energy is moderate (230), and the period is a middling 10 seconds, so it’s surfable but nothing to get excited about. The afternoon sees the wind pick up to 16 mph from the east-south-east, still offshore, but the conditions are a bit more marginal. Thursday is a write-off – rain showers, fresh offshore wind at 19 mph, and the swell drops to 1.6 ft with a long period of 13 seconds from the south-west. The energy is weak (151), and the surf is poor. It’s a day to stay on the beach.
Friday the 4th of September, the morning looks a bit better. The swell is still only 1.6 ft, but the period jumps to 20 seconds – that’s a very long groundswell from the south-west. The combined energy is moderate (365), and the wind is moderate offshore from the east at 12 mph. The conditions are good, but that tiny swell won’t give you much to work with. The
