The Lowdown
Alright, here’s the imperial version for the old-school crew.
First up, Thursday morning the 6th—swell running 11.5ft from the WSW with a 13-second period, southeast breeze at 9 mph, cross-off, keeping it clean. Energy’s moderate at 3920. Water’s a bit chilly at 58.3°F, so suit up.
Friday morning the 7th, lighter cross-on wind from the ENE at 6 mph, swell still solid at 11.5ft, period stretches to 14 seconds. Energy up to 4684. Friday afternoon is the standout—same 11.5ft swell, 15-second period, clean cross-off wind from the WSW at 9 mph. This is prime for an intermediate-friendly sandbar. Crowds often, but worth it.
Saturday the 8th holds 9.8 to 11.5ft swell with moderate energy. Sunday the 9th gets stronger SSE winds at 28 mph—still offshore and clean, but a workout to paddle. Energy peaks Sunday morning at 6378.
Monday the 10th drops to 6.9 to 8.2ft, shorter period around 9 to 10 seconds, wind cross-off from the SE. Still rideable.
Tuesday the 11th afternoon is a gem—swell down to 4.6ft but clean offshore south wind at 6 mph, 11-second period. Expect very good conditions for a longboard. Energy low at 1108, but quality’s high.
Wednesday the 12th is gold. Morning glassy with 6.2ft SW groundswell at a very long 18 seconds. Energy at 2461. Afternoon stays clean with 6.9ft SW at 17 seconds. Excellent for experienced surfers—long, lined-up waves.
Thursday the 13th morning gets a light cross-on from the NE, but afternoon goes glassy again with 6.9ft WSW at 16 seconds. Excellent.
Friday the 14th through Tuesday the 18th is mostly blown out—strong north winds, onshore, lumpy and choppy. Swell from 4.6 to 9.8ft but messy. Best to sit it out.
Wednesday the 19th turns around. Morning clean with light cross-off ESE breeze, 7.5ft WSW swell, 14 seconds. Afternoon even better—9.8ft WSW, 13 seconds, clean with gentle cross-off from the SE. Excellent for experienced surfers.
Thursday the 20th and Friday the 21st get blown out again—strong north winds, onshore, gale gusts Thursday afternoon. Avoid.

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.
