The Lowdown
G’day, I’m Rusty. Let’s have a look at what the next couple of weeks are shaping up like for Long Beach.
This is a bit of a tough stretch, honestly. The swell will be around, and there are some solid pulses, but the wind is going to be the spoiler for most of it. We’ve got wave energy from moderate all the way up to very strong (1530 to 4498 range) but the combo of strong cross-off and onshore winds makes most of it a write-off for clean surfing. The best windows are going to be later on, around the 19th and into the following week, when the breeze finally takes a break.
Alright, starting now. Friday the 11th and Saturday the 12th are a no-go. You’ve got a strong 10 ft swell from the SE with a short period (7 seconds) on Friday, but it’s windy with a 31 mph cross-off, so the surf is poor. Saturday pumps up with a bigger 8 ft SW groundswell (16-second period) and combined energy hitting 4498, but that strong 28 mph cross-off wind just ruins it.
Sunday the 13th through to the 18th is a real grind. Swell sizes stay between 3 ft and 8 ft, mostly from the SW, with good period – 12 to 16 seconds – so there’s plenty of energy. But the wind is relentless: fresh to strong breezes from the SE or NNW, mostly cross-off. The surf is consistently scored as marginal or poor. Not worth paddling out.
Now, here’s where we get a bit of hope. Saturday the 19th looks like the first real standout. In the morning, the wind drops right out to 3 mph from the E with a clean cross-off, and you’ve got a nice 7 ft SW swell (13 seconds, moderate energy of 1619). The afternoon gets even better – the wind swings SSE at 9 mph, turning offshore, with a 6 ft SW swell. The surf here is expected to be very good. Keep in mind, Long Beach can get crowded, so expect some company.
Then Monday the 21st is possibly the pick of the whole run. Morning brings glassy conditions with the wind at 3 mph from the SE and a solid 7 ft WSW swell, 15-second period, giving us a long-period groundswell. Combined energy is 1898 – solid moderate. This is going to be clean as a whistle and excellent for a confident intermediate surfer. The afternoon stays clean with a light offshore, 7 ft WSW swell.
Tuesday the 22nd is another frustrating day – the wind turns onshore from the N at 22 mph, and while there’s a 7 ft NW swell, the short 7-second period and messy wind make it ugly.
The end of the forecast period starts to look promising again. Friday the 25th has a good morning with 7 ft SW swell, 12-second period, and a gentle 9 mph cross-off. By the afternoon, the wind goes offshore at 9 mph from the SSE, giving nice clean 7 ft sets. Expect some quality waves. Finally, Saturday the 26th looks sweet: glassy in the morning with light wind from the WSW, 5 ft SW swell, and the afternoon cleans up with a 6 ft SW swell and clean conditions.
Water temp at the start of this period is sitting at 59°, which is about 1° cooler than average – nothing wild, just a touch crisp for the time of year.
That’s the story. A lot of wind to push through, but there are a couple of premium sessions waiting for you around the 19th and 21st, and again on the 25th. Stay patient.

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.
