The Lowdown
Right then, let’s have a look at what’s on the cards for the next couple of weeks.
First thing to say: we’ve got a long, frustrating wait ahead. The early part of the forecast is a write-off. From now, right through the weekend and into early next week, the wind is howling onshore and the surf is just plain ugly. It’s not worth paddling out. We’re talking strong, messy winds and lumpy, choppy conditions. Hang tight. This gap of no-go surf stretches for a good five or six days.
Jongensfontein is the only game in town, and it only really starts to come alive around Tuesday the 15th of September. Tuesday morning is the first real glimmer of hope. We’ve got a clean, gentle offshore wind from the NW, with the swell running at a manageable 5ft from the East, with a period of 10 seconds. The combined energy is moderate at 678, so it’s not a powerhouse, but it’ll be clean and fun. This is the standout for the whole outlook.
The water is running at a temperature that’s about average for this time of year, so no nasty surprises there.
After that, the wind swings around again and things get marginal through the week, with a lot of cross-onshore and onshore slop. The swell picks up, but it’s messy.
The real event is a week and a half away, on Wednesday the 23rd of September. The afternoon session is an absolute belter, but it’s only for the experienced crew. We get an 12ft southwest groundswell rolling in with very long 13-second intervals, pumping combined energy of 4028 (strong to very strong). The wind is cross-shore with a bit of a chop, and the forecast says it might actually be too big for this reef setup. This is expert territory, no question. A real beast of a day if you’ve got the nerve.
The following morning, Thursday the 24th, still holds some size at 8ft with clean-ish cross-offshore wind, but the winds will be howling later.
So, in short: this is a 16-day window that doesn’t really get going until next week. The clear best on offer is the clean, gentle offshore session on Tuesday morning, the 15th. The big pulse on the 23rd is a promise of power, but only for the brave.
