The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for Long Beach over the next couple of weeks.
The waiting game is on for a few days. The surf picks up Wednesday afternoon with a clean 4ft WSW swell, but it's the Sunday the 30th of August that gets my blood pumping. That morning we’ve got a solid 8ft WSW groundswell thumping in with a 13-second period, and the wind is a clean cross-off from the SSE. This is proper, powerful surf – moderate combined wave energy (2012) – and it’s going to be a sight. The water temp is sitting at 59°, which is about average for this time of year, so no surprises there.
The standout of the whole run, though, is the first week of September. Tuesday the 1st looks messy with a strong onshore wind, but hold on for Wednesday the 2nd. We’ve got a massive 13ft SW groundswell rolling in, and the wind swings offshore from the S, setting up some serious, powerful walls. This is for experienced surfers only – the combined energy is a massive 5096. That’s a big, heavy ocean. Thursday the 3rd of September is just as good, with a 10ft SW swell and glassy conditions in the morning. That’s as clean as it gets.
Things start to drop off after that. Friday the 4th sees strong winds and a short-period SE windswell, and the surf goes quiet by the 7th and 8th. There’s a small, clean window on the 8th with a 3ft SW swell, but it’s nothing to write home about. The second week is mostly flat or blown out, so if you’re looking for waves, aim for that first week of September.

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.
