The Lowdown
Alright, Rusty here. Let’s break down Long Beach in feet and miles per hour for the local crew.
The setup is a sheltered sandbar that breaks fairly consistently, and the water’s at 58°, which is a bit colder than typical for this time of year—about 3° off, so you’ll feel that chill.
First few days are a total bust. Friday the 4th and Saturday the 5th have cross-off winds howling at 25 to 37 mph, with a messy 10 to 12 foot swell from the SSE and a short period. That’s blown-out garbage. Stay home.
On Sunday the 6th, the afternoon finally cleans up. We get a 7 foot SW groundswell with a 16-second period and a gentle 9 mph breeze from the SE—glassy, clean conditions. The wave energy is strong (2675). That’s a decent window for experienced surfers only.
Tuesday the 8th morning is glassy but small—5 foot swell, weak energy. Wednesday the 9th morning picks up with a light offshore breeze and a clean 4 foot SW swell—rideable but small.
Then Thursday the 10th is the first real standout: offshore wind at 12 mph, a building 8 to 10 foot SW groundswell with a 13-14 second period, and energy readings over 2394. Clean and solid. Good for intermediates and above.
After that, it turns ugly again. Friday the 11th through Monday the 14th are all cross-off or cross-on slop with strong winds. Not worth it.
Tuesday the 15th and Wednesday the 16th stay poor with onshore winds and lumpy conditions.
Thursday the 17th morning brings a clean 6 foot SW groundswell with offshore wind at 15 mph—nice and tidy.
Now for the big one: Friday the 18th. Morning is dead calm, glassy, with a 15 foot SW groundswell building from a 14-second period. The wave energy is massive at 7375. That’s groundswell power. It’ll be big and clean, but only for experts. The wind stays light offshore in the afternoon at 9 mph. This is the best day of the entire forecast.
Saturday the 19th is still fun: a clean 6 foot SW groundswell with offshore wind at 12 mph in the morning.
So, first week’s mostly a dud except for Sunday afternoon the 6th and Thursday the 10th. Second week builds to that killer Friday the 18th. That’s the one to aim for.
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.
