The Lowdown
Hey, Rusty here again. Let’s break down what’s coming for Long Beach over the next couple weeks.
We’ve got a quiet start, with nothing worth chasing until Sunday afternoon the 6th. After that, it’s a story of big, long-period groundswells getting hammered by tricky winds. The water is sitting at 57°, which is about 3° colder than normal for this time of year – that's a proper chill.
Sunday afternoon (Sept 6th) gets us going with a solid 7ft SW swell and a long 16-second period. The energy is pumping at (2685). The wind is cross-off from the SE at 15 mph, so the surface should stay clean. Not a bad start.
The real highlight is Monday afternoon (Sept 7th) . The swell drops to a clean 7ft from the SW with a 13-second period (1398 energy), but the wind swings to a light offshore from the SSW at 10 mph. This is your best bet – clean, lined-up waves with good power.
Tuesday morning (Sept 8th) is small but perfect. The swell is only 3ft from the WSW, the energy drops to (585), and the wind goes glassy. Ideal for a longboard if you just want a cruise.
From Wednesday (Sept 9th) onward, the wind gets nasty. We see a huge pulse on Thursday morning (Sept 10th) with an 12ft SW groundswell and 16-second period – energy is massive at (5750). That's a heavy, expert-only wave, but the cross-off wind keeps it rideable. The problem is Friday (Sept 11th) and beyond, where the wind screams from the SE at 50 mph, trashing the surface.
There is a glimmer in the second week on Wednesday morning (Sept 16th) . A 7ft WSW swell with a fresh offshore breeze from the SSE gives you clean conditions and strong energy (2094). Worth watching.
Saturday (Sept 19th) and Sunday (Sept 20th) have solid 6ft to 8ft SW swells, but the cross-onshore wind will make it lumpy.
Monday (Sept 21st) finishes off with a 6ft SW swell and clean offshore winds in the afternoon – another solid option if you’re patient.
To sum it up: your best window is Monday afternoon (Sept 7th) for the cleanest waves with decent size. The massive 12ft swell on Thursday (Sept 10th) is for the brave only, and the wind isn’t ideal. The second week is a dice roll with the wind, but that Wednesday morning (Sept 16th) could be a sleeper.
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.
