The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for Long Beach.
To be straight with you, this 16-day stretch is a tough one. We’re seeing a long gap at the start with basically nothing to get excited about. From now until late in the month, it’s a whole lot of poor surf conditions with tiny, weak swell and a lot of onshore wind. You’re looking at wave heights barely getting to 1 foot, mostly from the SE at a short period. The combined energy is embarrassingly low, so not worth paddling out for.
Around the 21st of September, things finally start to pick up. There’s a bit more size on offer with 4 to 5 foot swell from the ESE, and it’s coming with those stronger NE cross-offshore winds that clean it up nicely. The combined swell energy jumps up significantly, so there's some proper push. Still, the surf conditions are rated as poor. At 5 foot with a short period plus those strong winds at 18 to 25 mph, this is more of a windy, choppy session than a glassy one. It’s not ideal for surfing to be honest, those winds are solid.
The standout for the whole outlook, if you really want to find a window, is the morning of the 24th of September. We get 6 foot of ESE groundswell (9-second period) with a strong offshore wind from the NE at 25 mph. The combined energy is pumping hard, so the ocean has some serious power. This is a clean, lined-up look, but that wind is howling. It’ll be tough to paddle into and hold your line, so this one is for experts only. You’ll need your A-game.
Overall, it’s a bleak run for Long Beach with only one or two blips of interest. The water temp is 74°, which is about 4 warmer than normal, so it’s muggy out there.
Stay patient, folks. Rusty out.

Information about the Long Beach Surf forecast
The above surf forecast table for Long Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Long Beach can be found by selecting the local surf guide option on the grey menu. Our Long Beach 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 (Long Beach) 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 Long Beach 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.
