The Lowdown
Alright folks, I gotta level with you – the surf at Jupiter Inlet South Jetty over the next sixteen days is basically non-existent. From now through to the 11th of September, we’ve got a run of flat, weak conditions and not a single solid option. The score is zero across the board, and that’s being generous.
Starting Thursday the 27th of August, we’ve got a tiny 0.7ft (0.2m) swell coming from the east-northeast. Combined energy is a weak 38. Water temp is sitting at 87°F, which is a touch warmer than usual for this time of year. Wind is a light cross-shore from the south-southeast in the morning, but the swell just has no power. The period is 15 seconds, so it’s a long period groundswell, but with that height, it’s nothing but a ripple on the jetty.
The rest of the month and into early September is more of the same. We get a few bumps up to 2ft (0.7m) on the 30th of August, but that’s windswell from the southeast with a period of just 4 seconds – all chop and onshore wind. Most energy readings stay under 50. On the 8th of September, we see a glassy morning with a light north-northwest breeze, but it’s only 1ft (0.4m) from the northeast at 9 seconds. Not worth the walk.
The one time the energy gets going is on the 9th of September – combined energy hits 126 in the morning and 130 in the afternoon. That’s moderate, but the swell is only 2ft (0.5m) from the northeast with a 12-second period. That’s a nice long period groundswell, but it’s still just knee-high. The wind is light and cross-on from the east-southeast, so it’ll be a bit bumpy. The jetty can handle that period, but without height, it’s a no-go.
Bottom line: nothing to ride for two weeks. Swell never gets over 3ft (0.9m), and most days are well under that. Wind is rarely clean. For the area, this kind of dead stretch is pretty normal, but it doesn’t make it any less frustrating. Best to stay home and wax up for next time.
