The Lowdown
G'day, I'm Rusty. Let's have a look at what's on offer at Long Beach for the next couple of weeks.
Alright, straight up, the next few days are pretty ordinary with a lot of wind and messy conditions. We've got a bit of a wait on our hands for the real quality to show. The first standout is a beauty on Saturday the 19th of September, with clean, fun-sized swell and light winds, and then there's a much bigger, more serious pulse on Friday the 25th of September that'll only suit the experienced crew.
The water temp here is sitting at about 58°F, which is a bit colder than normal for this time of year, so you'll want a decent wetsuit.
Sunday the 13th starts off okay – you'll get 7ft of SW swell with a solid 14-second period (moderate wave energy around 1964). The wind is light and cross-offshore, so the morning session is actually clean. But the afternoon turns onshore and gets a bit iffy. Monday the 14th and Tuesday the 15th are write-offs – strong winds and messy conditions with short-period slop. Wednesday the 16th is a bit cleaner with cross-off winds, but the strong breeze makes it a tough call, with 8ft of WSW swell (2863 – strong energy). Thursday the 17th is similar, still too windy. Friday the 18th is still pretty breezy.
Now, here's the first proper standout. Saturday the 19th – this is the one to circle. The morning has 6ft of SW swell with a 14-second period (1459 – strong energy), and a light cross-off breeze making it clean. But the afternoon is where it's at: glassy offshore winds from the south at 9 mph, with 6ft of SW groundswell. That's gentle offshore and clean – proper fun waves for an intermediate. Crowds are possible here, so get in early.
Sunday the 20th keeps the good run going with clean conditions, light winds, and solid 6ft to 6ft SW swell. The afternoon has a gentle offshore wind again. Monday the 21st sees a new WSW swell building to 7ft with a 15-second period (2015 – strong energy), but the wind picks up, making it a bit messy. Tuesday the 22nd is cleaner again with moderate winds. Wednesday the 23rd starts to fade. Thursday the 24th is a write-off with near-gale winds.
Then we get to the next big one. Friday the 25th of September – this is for the experienced crew only. The morning sees a big 12ft WNW swell (2487 – strong energy) with a 10-second period, and light cross-off winds making it clean. The afternoon jumps to 15ft of WNW swell (4298 – very strong energy). That's big, powerful, and not for beginners. Saturday the 26th stays big with 12ft of W swell (2528 – strong energy), but the wind is up, making it a bit tricky. Sunday the 27th is still big but very windy.
Finally, Monday the 28th of September has a monster pulse: 12ft SW swell with a 14-second period (7388 – very strong energy) in the morning, and 16ft of SSW swell (7341 – very strong energy) in the afternoon. That's massive, heavy, and only for the absolute experts, and the wind is strong, so it'll be a handful.
So, to sum it up: the best all-rounder for clean, fun waves is Saturday the 19th. For the big-wave crew, Friday the 25th and Monday the 28th are the ones, but be prepared for size and power.
Rusty.

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.
