The Lowdown
Alright, let's get into it. This is Rusty, and I'm looking at what we've got coming up for Long Beach.
The swell window opens on Thursday the 10th morning with some decent energy. We’re looking at a solid 8 ft SW swell with a period of 14 seconds, and the wind is offshore from the SSE at 12 mph. The water’s sitting at a cool 59°, which is a bit colder than normal for this time of year, so you might want an extra layer. The combined energy is strong at 2590, and it’s clean surf, but this is meaty stuff—definitely for experienced surfers only. That afternoon, the swell shifts a touch to WSW at 8 ft, still cleaning up with offshore winds, but the quality dips a bit.
Then we hit a rough patch. From Friday the 11th right through to around Thursday the 17th, it’s mostly blown out or messy. Strong winds, cross-off conditions, and the swell quality just isn't there for a good paddle. You’re looking at about a week of pretty average conditions, with a few days of marginal surf that’s more of a headache than a highlight. The energy drops and picks up, but the wind never really plays ball.
Now, here’s the standout. Mark your calendar for Saturday the 19th. That morning is absolute magic. The wind goes glassy—0 mph from the south—and the swell is a clean 7 ft from the WSW with a long 16-second period. The water’s a bit warmer than that first window, and the combined energy is strong at 2546. This is excellent for experienced surfers, and with glassy conditions, it’s going to be clean as a whistle. The afternoon holds up too, with gentle offshore winds and 8 ft WSW swell. This is the pick of the whole outlook by a long shot.
Following that, Sunday the 20th brings a big pulse of SW swell, hitting 10 ft in the morning, but the wind picks up to a fresh breeze, making it a bit of a handful. The energy is very strong at 6013, but for most, it’ll be too big and choppy unless you’re an expert. The rest of that week is a mix of smaller swells and cross-off winds, with a few marginal windows for a paddle if you’re desperate.
Overall, the best session is that glassy Saturday the 19th. The first couple of days are decent and powerful, but then you’ve got a long stretch of dud conditions before that one golden morning. Keep an eye on it, but don’t bother with the second week unless you’re bored.
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.
