The Lowdown
G'day, I'm Rusty, and here's your surf outlook for Long Beach.
The water temp is feeling about average for this time of year, so your usual wetsuit is the go. We're starting this Saturday morning, August 15th, with a real beauty. The surf is a solid 6ft from the WSW, with a 14-second period, pumping out 1261 units of combined energy. The wind is dead glassy from the SE at just 3 mph. It doesn't get any cleaner than that. The afternoon stays clean with a light cross-off breeze, but the swell picks up a touch.
Sunday, the 16th, is a total write-off. An onshore wind from the north blows it all to hell. Monday the 17th is still messy in the morning, but the afternoon turns it around. The wind swings to a cross-off, the swell cleans up, and the energy is a solid 2725. You'll need to be an experienced surfer here because the wave state is excellent, but the size is up around 8ft, so it's a big one.
The middle of the week (Tuesday to Wednesday) is a period of onshore and cross-off winds that keep the surf in a marginal state. The size stays up, but the winds are too strong, especially on Wednesday when we see a fresh breeze of 19 mph. The best bet for the second half of the week is Thursday, August 20th. The wind swings offshore from the SSE, giving us clean, groomed lines. The swell is a consistent 7ft from the SW. Then Friday, August 21st, starts with a glassy clean morning, but the afternoon gets a bit cross.
Looking further out, there's a huge pulse of swell heading our way for the weekend of August 22nd and 23rd. The combined energy rockets up to over 4000 and 5000, but it's accompanied by a screaming wind. Saturday has a near-gale wind, making it a total mess for surfing. Honest to God, that setup on Saturday with the big swell and strong wind is more of a kite surfer's dream.
The standout for the second week is early Tuesday, August 25th. We've got an 8ft swell from the SW with a very long 17-second period and a massive 4191 units of energy. The wind is a gentle cross-shore, so it's not perfect, but that long period groundswell is what we live for. It'll be best at a point or a reef, as a beach break might get a bit shifty with that long period. The rest of the second week is a mixed bag of onshore winds and marginal conditions, with a final chance of some clean, offshore winds returning on Friday, August 28th, but with a fresh breeze.
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.
