The Lowdown
Alright folks, let’s talk about Broadhaven South for the next couple weeks. It’s a sheltered spot that only works when everything lines up, and right now, the deck is stacked against us.
Water temp is a warm 64°, which is much warmer than normal – feels good on the skin, but that’s about the only highlight.
First shot of surf hits Sunday morning, September 13th. We’re looking at 5-foot swell out of the WSW with a 10-second period. That’s got some real energy behind it (combined energy of 435). The morning looks clean on the surface, but it’s a cross-off wind 12 mph from the WSW – fighting the swell direction. The report says it’s marginal and tide-dependent. It’s doable, but not worth rushing out for. It drops to 5-foot by the afternoon and goes poor.
Monday the 14th, the wind blows 15 mph and the swell drops to 4-foot. The energy is fading fast. The whole week is that grind: Tuesday the 15th bumps to 6-foot early with a clean offshore wind 22 mph from the WNW, but the period is a lousy 7 seconds – that’s weak, wind-driven junk. Energy is only moderate at 335.
Wednesday the 16th morning offers 4-foot with a clean offshore 15 mph from the NW and a 10-second period. The report says “surfable but very ordinary”. That’s the high-water mark for the first week.
The one real standout – and I mean the only one – comes Saturday morning, the 19th. Swell jumps to 7-foot out of the WSW with a short 7-second period. Combined energy hits 494 – moderate, but solid for this spot. The wind is 19 mph from the W, cross-off, and it’s clean on the face. This is the biggest swell of the whole window. But here’s the reality: 7-foot with a short period at a beach/reef break is going to be a chaotic, closeout mess. That’s expert-only territory. If you’ve got the skills and want to fight, there’s power there, but don’t expect a smooth session.
After that, it’s a flatline. From Wednesday the 23rd right through to the 28th, we’re under 2-foot with mostly onshore or cross-onshore winds. The energy numbers drop to single digits – that’s just ripple. Even the glassy morning on the 28th with less than 1-foot and 3 mph wind is a dead flat lake. That’s over a week of nothing.
The bottom line: Hit that Saturday the 19th morning if you’re an expert looking for a scrap with a lumpy, short-period pulse. It’s the biggest energy of the run. For everyone else, it’s time to wax the longboard and wait.
