The Lowdown

Rusty here again, with the same read in feet and miles.

We’ve got a slow start at Long Beach. The first few days are mostly messy, with a stiff crosswind and lumpy stuff. You’ll be waiting until Sunday morning, September 20th for the first real opener.

That morning on the 20th is your best early bet. The water is about normal for mid-September. Swell is 6ft from the SW, period at 13 seconds – plenty of shape and power for a sandbar. The energy is moderate (1150), but the big story is the glassy surface. Zero wind means butter-smooth takeoffs. It’s a rare treat for this spot, and it’ll draw a crowd, so paddle out early. It could be inconsistent, so take what you get and make it count.

Skip ahead to Friday afternoon, September 25th. The swell bumps to a solid 8ft from the SSW, which is big enough to keep the beginners on the sand. It’s got a moderate to strong energy (1516) and a gentle offshore wind. Super clean, punchy, and great for anyone with a bit of experience. This is a proper afternoon session.

The best stretch of the whole 16 days comes at the end. Sunday, September 27th morning and afternoon are both absolute bangers. Swell is at 8ft from the SW and WSW, period hitting 16 seconds – that’s serious groundswell. The energy is very strong (3534) and you’ve got offshore winds the whole time. It’s going to be big, clean, and powerful. This is expert-only territory, but for those who can handle it, this is the day. Mark it down.

Between now and then, there are a few clean-ish days in the second week, but the swell is small or the wind is borderline. The 20th, the 25th, and the 27th are your windows. Don’t waste your time on the rest.

Get out there when it’s right.

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.
