The Lowdown
Alright folks, Rusty here. Let’s be straight with you – for the next sixteen days at L Jetty, there ain’t much to get excited about. The whole window is looking pretty lean. We’ve got a big gap with no real surf to recommend.
In fact, the first recommendation doesn’t come until the very end of the period. From now through to about the 22nd of September, it’s basically a write-off. The swell is tiny, the winds are messy, and the energy is pathetic. The water is sitting at a very warm 74°F , which is 5°F above normal – feels more like a bath than the ocean.
The first time we even get a sniff of something surfable is on Wednesday the 23rd of September. The swell picks up to 5ft from the southeast with a period of 7 seconds. The combined energy climbs to 237 (moderate wave energy), so there’s finally some push. But the wind is cross-shore from the north at 9 mph , keeping things a bit lumpy. It’s marginal, but it’s the best we’ve seen in a while.
The next day, Thursday the 24th of September, looks a touch cleaner. We get a 3ft southeast swell, period still around 8 seconds, and the direction is still angled in. The real win here is the wind swinging offshore from the west-southwest at 12-16 mph. That’s going to scrub the faces up and give you something to work with. Energy is moderate at 129. It’s not going to be pumping, but you’ll get a few clean lines if you hunt them out.
Friday the 25th of September is more of the same: 3ft from the east-northeast, but the wind stays offshore from the west at 16 mph. The energy drops a little to 98 (weak), so the waves will be smaller and slower, but clean. Good for a longboard paddle.
Then we roll into Saturday the 26th of September. This is probably the standout, and I mean the only true standout of the whole run. The swell nudges up to 4ft from the east with a period of 6-7 seconds. The energy is back into moderate territory at 144. But the key is the wind – it’s light or calm from the north-northwest, giving us clean, glassy conditions. This is your best chance for a session that actually feels like surfing. Get on it.
After that, it’s back to the doldrums. Sunday the 27th sees the swell drop back to 3ft and onshore easterly winds mess things up.
So, to sum it up: You wait until the 23rd, but the real gem is Saturday the 26th. Clean conditions and a little bit of size from the east. Don't hold your breath for the rest.
Rusty.

Information about the L Jetty Surf forecast
The above surf forecast table for L Jetty provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at L Jetty can be found by selecting the local surf guide option on the grey menu. Our L 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 (L 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 L 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.
L Jetty is 3 km (2 miles) from Asbury Park. If you plan a vacation in New Jersey, look for hotels and other accommodation in Asbury Park. Asbury Park has rooms for a wide range of budgets as well as car hire and transport links.
