The Lowdown
Alright, Rusty here again. Let’s break this down in feet and degrees Fahrenheit for the same stretch.
First up, the water temp is about 57°F, which is nearly 4°F colder than normal for this time of year, so you’ll want the 4/3.
The forecast starts on Thursday the 13th, but don’t rush out. The wind is cross-onshore from the NNE at 9 mph, pushing into a 8ft swell from the SW with a very long 17-second period. That’s a ton of energy (3976) but it’s messy and the long period groundswell is going to close out the sandbars. Choppy and tough.
Friday the 14th is a complete washout with onshore winds all day.
Now, Saturday the 15th is where it gets interesting. Morning is glassy – wind drops to just 3 mph from the south, near flat calm. Swell is a clean 6ft from the WSW with a 14-second period (1335 energy). That’s the best early window: clean, glassy, and surfable. Afternoon stays clean with a light offshore breeze. That’s your first real standout.
Sunday the 16th gets blown out again.
Monday the 17th afternoon is a winner. Offshore wind from the SSW at 6 mph, swell at 7ft from the W, 12-second period (2146 energy). That’s excellent, clean, powerful stuff for experienced surfers.
Midweek (18th-20th) is mostly marginal with cross or light cross-off winds as the swell drops off.
Second week gets real good. Saturday the 22nd is the big standout. Morning has a gentle offshore from the south at 9 mph, with a 8ft groundswell from SW at 14 seconds, pumping (2930 energy). That’s powerful, clean, and full of push. Afternoon stays clean and excellent for experienced surfers. That’s the session of the outlook.
Sunday the 23rd stays solid but the wind picks up from the SE. Monday the 24th is a clean, fun-sized 5ft.
Then we get a late monster. Thursday the 27th afternoon: solid 12ft from the WSW, 15-second period, offshore wind from the SSE at 12 mph, energy at 5531. That’s huge, clean, and only for experts. Friday the 28th holds similar size but with cross-off winds.
Main standout: Saturday the 22nd. Honourable mention to Monday the 17th afternoon and Saturday the 15th morning for cleaner, more manageable conditions.

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.
