The Lowdown
Alright folks, Rusty here. Let’s talk about what’s shaping up at Long Beach.
We’re looking at a run that starts off a bit average, but there’s some real firepower waiting in the second week. The water is 58°, which is a bit colder than normal for this time of year, so don’t forget the booties if you’re heading out early.
The first few days are a hard pass. Monday the 10th has some cross-off wind howling at 25 mph, and the wave energy is high (1626) but it’s messy. It stays marginal through Tuesday and into Wednesday morning, even with a building swell. Wednesday the 12th afternoon is where it starts to get interesting. The wind drops to a gentle cross-off, the swell is 7 ft from the SW with a period of 17 seconds, and the energy hits 2616. That’s proper groundswell, and it’ll be clean. It’s a bit heavy for beginners at that size, but for the experienced crew, that’s your first real window.
Thursday the 13th through Friday the 14th morning are a write-off – onshore winds and bumpy conditions. But then Friday the 14th afternoon, the wind goes glassy. It’s 7 ft from the WSW with a 14-second period, and the energy is 1701. That’s a lovely session if you can sneak out.
The real standout, though, is Monday the 17th and beyond. Monday the 17th morning has a solid 10 ft swell from the WSW, 15-second period, with a gentle cross-off breeze. The wave energy is massive at 4462. That’s a big day – expert territory, no doubt. And in the afternoon, the wind drops to glassy, same 10 ft swell, energy at 3288. That’s the pick of the whole forecast. It’s a bit of a wait, but it’ll be worth it.
Tuesday the 18th afternoon is also a winner with a clean offshore wind and 7 ft from the WSW. Saturday the 22nd and Sunday the 23rd are fire, too. Saturday afternoon has a clean offshore breeze, 8 ft from the WSW, 16-second period, and energy at 3599. Sunday the 23rd morning is the same story: 8 ft, 14-second groundswell, gentle offshore, 2615 energy. Then Sunday afternoon, it goes to 10 ft from the SW, 14 seconds, with a moderate offshore. That’s another big, clean, powerful day.
There’s a bit of a gap in the middle of the second week, with Thursday the 20th afternoon being the only clean option before the weekend. The last few days drop off.
So, if you’ve got patience, wait for Monday the 17th or that weekend of the 22nd and 23rd. That’s the proper stuff.
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.
