The Lowdown
IMPERIAL VERSION
G’day crew, Rusty here. Let’s break it down for Riviere Noire Harbour. This sandbar’s got a building swell window, but there’s a mellow start and some lumpy days before the real juice arrives.
Water temp is 77°, which is a touch warmer than usual for this time of year. Over the first weekend – Thursday 6th to Sunday 9th August – we’ve got clean offshore winds all day, but the swell is small with combined wave energy from 316 to 1118 (weak to moderate). Thursday morning has 3ft from the SSW with a 14-second period (groundswell), but energy (343) is low. Friday drops to 2ft – 2ft. It’s clean but for a fairly exposed sandbar you’re scratching for wave.
Monday 10th August stays similar with rain showers and a cross-off wind by afternoon. Still 4ft to 4ft but quality drops. Tuesday 11th though – that’s the spark. Clear, 20 km/h offshore east wind, 4ft SW swell, 15-second period, energy hits 704 (moderate) and 919 in the arvo. This is clean groundswell. Crowds are possible, but for a fairly consistent sandbar, it’s worth it.
Wednesday 12th holds 4ft with gentle offshore breezes in the morning – glassy and good.
Thursday 13th dips into marginal conditions with lower energy. But Friday 14th morning – here we go – 6ft from the SSW, 13-second period, energy of 1456 (strong). This is excellent for experienced surfers. Clean offshore at 25 km/h. The afternoon jumps to 7ft with fresh 30 km/h wind and energy at 1850 – powerful but period shortens, making it a bit unruly.
The big standout? Saturday 15th August afternoon brings 7ft from the south with an 18-second period and energy of 6180 – very strong, very long-period groundswell. That’s a dream for a reef, but on a sandbar it might run straight. Still, the power is unreal. Sunday 16th August morning is 8ft from the south, 16-second period, energy of 5890 – expert territory only, with 20 km/h offshore wind keeping it clean. Sunday afternoon gets messy with rain and 30 km/h wind on 12ft – that’s heavy.
Monday 17th drops to 7ft, still strong. From Tuesday 18th through Thursday 21st August it fades to 4ft to 5ft with moderate energy and clean winds but marginal quality. Friday 21st August has a new 3ft to 4ft SW pulse with 15-second period and energy over 1308, but wind hits 30-35 km/h, chopping it up.
Best on offer? Tuesday 11th August morning for the clean, consistent 4ft session. Sunday 16th August morning for the big, deep-water, expert-level groundswell. The gap from the 12th to the 14th is a bit of a wait, but once it fires, it’s worth it.
Rusty out.
