The Lowdown
Alright, Rusty here. Let’s have a look at what we’ve got for North Jetty.
Honestly, it’s a rough stretch ahead. The next couple of weeks are looking quiet, and there’s no real surf to get excited about. The first half of the period is mostly flat and small, with the few little bumps we see getting ruined by the wind direction and short-period slop. The water temp is sitting at 84°, right on the money average for this time of year, so at least it’ll feel nice just floating around.
Friday the 14th has a little 2ft SE swell, but it’s only a 3-second period—so it’s just wind chop basically—and there’s a risk of thunderstorms. Not worth paddling out.
Saturday the 15th and Sunday the 16th see tiny 1ft to 2ft SE swell with period barely in the 7 to 8-second range. The combined energy is pitiful, in the 12 to 33 range. The morning of Sunday the 16th has clean conditions with a light offshore from the west, but there’s just no wave power. You could probably sit on a foamie and not get wet.
Monday the 17th through Wednesday the 19th stays small—1ft to 2ft—and the period is short except for Tuesday afternoon, which shows an 11-second ESE swell. That’s a longer period, and the combined energy climbs to 69, which is still weak but at least feels like a real swell. The wind on Tuesday the 18th afternoon is a light cross-offshore from the SSE, keeping things clean. That’s the closest we get to a shreddable wave in the first week, but honestly, with only 2ft of height, it’s a longboard or a skim board day.
After that, we drop right back down. From Thursday the 20th through Monday the 24th, it’s back to 1ft to 2ft junk—most of it short-period windswell, with combined energy under 65. Winds are often cross or cross-onshore, making it choppy and bumpy. The morning of Friday the 21st has a clean offshore west wind, but the swell is only 1ft. Not happening.
The only standout, if you can call it that, arrives Thursday the 27th of August—about two weeks out. That morning we see a 3ft ESE swell with a 10-second period, and the combined energy jumps to a moderate 155. That’s the first time we see three-digit energy. BUT the wind is a cross-onshore from the NNE at 9 mph, so it’s going to be bumpy and blown out. The swell direction is from the ESE, which is not the optimum NE direction for this spot, so it won’t wrap in well. That afternoon the wave energy drops to 112, but the wind shifts to a full onshore, making it even worse.
Bottom line: There’s no truly good surf in this 16-day window. The best you get is a tiny, clean longboard session on Tuesday the 18th afternoon, and a slightly bigger but messy swell on Thursday the 27th that will be hard to enjoy. The rest is flat or wind-chopped. For a beach/pier setup like North Jetty, long-period swells can run straight and close out, but we aren’t even getting that problem—we just aren’t getting any real swell. The consistent lack of size and quality is a bummer, but this area can go quiet like this. Hope a late-season storm changes things up.
Rusty.

Information about the North Jetty Surf forecast
The above surf forecast table for North Jetty provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at North Jetty can be found by selecting the local surf guide option on the grey menu. Our North Jetty surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (North Jetty) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for North Jetty may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
North Jetty is 12 km (7 miles) from Jacksonville Beach. If you plan a vacation in North Florida, look for hotels and other accommodation in Jacksonville Beach. Jacksonville Beach has rooms for a wide range of budgets as well as car hire and transport links.
