The Lowdown
Alright folks, Rusty here. Let's take a look at what's shaping up for Long Beach over the next couple of weeks. We've got one break on the radar, a sandbar setup that's pretty sheltered, so it needs the right direction to light up.
The coming days are a bit of a mixed bag. There's some size and energy coming through, but the wind is going to be the main player here, and not always in our favor. The best windows are going to be when that wind drops right off or goes offshore.
We kick things off on Sunday the 9th with a chunky 13ft SW swell, and the wave energy is strong at 7238. A strong SSE breeze is blowing offshore though, which means clean, lined-up faces. It's a handful at that size – definitely one for the experienced crew only, and you'll be working hard to get out the back.
Monday the 10th is a write-off. Strong cross-off winds and dropping swell make for messy conditions. Tuesday the 11th sees the swell drop further, but by Tuesday afternoon we've got a light SE breeze making it cross-off. The swell is 4ft from the SSW with a solid 12-second period. It'll be clean, but smaller.
Wednesday the 12th is where things get interesting. The morning is a little lumpy with a cross-on breeze, but Wednesday afternoon is the standout for the first week. We've got a 7ft SW groundswell with a long 17-second period and light SE cross-off winds. The wave energy is moderate at 2893. That long period will wrap nicely into this sheltered sandbar, and with clean conditions, it's calling all experienced surfers for a proper session.
Thursday the 13th gets blown out again with a moderate onshore breeze and a big 8ft swell. Too lumpy. Friday the 14th through Saturday the 15th are small and unexciting.
Now, hold onto your leggies for Sunday the 16th. By the afternoon, we've got a clean 8ft WSW swell with a gentle SSW offshore breeze. That is a beautiful combo, and the wave energy is solid at 2110. This is a prime window.
But the real gold is Monday the 17th. Glassy conditions in the morning with a 10ft WSW groundswell, 15-second period, and massive wave energy of 4454. It's big – 8ft to 10ft is expert territory – but with a glassy surface and that long-period energy, it will be a day for the bold. The afternoon holds the same quality.
After that, the swell drops right off. Tuesday the 18th is a shadow of the day before, and from Wednesday the 19th through Friday the 21st, we're looking at a flat spell with strong winds. A real, boring gap.
We get a little life back on Saturday the 22nd with a small, clean 4ft to 4ft swell and light offshore winds. Fine for a log or a funboard.
The forecast is pointing to an epic finish. On Sunday the 23rd, a new SW groundswell arrives at 8ft in the morning, building to 10ft by the afternoon, with a clean 15-second period and offshore winds. Wave energy is strong at 3515. That is the best-looking swell of the whole run. Bring your big-wave board and your courage. Monday the 24th holds size at 10ft but the wind swings cross-off, making it less perfect.
So, to boil it down: the two standout sessions are Wednesday afternoon the 12th and Monday the 17th for world-class conditions. But if you want the biggest, cleanest swell of the forecast, you wait for Sunday the 23rd. That's the one.
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.
