Table - best surf conditions forecast for Long Beach over the next 16 days.
Alright folks, Rusty here. Let’s have a look at the next 16 days for our local stretch of sand.
It’s a slow start, with the first few days looking pretty flat and messy. The water temp is sitting at 59°F, which is about average for this time of year, nothing weird going on there. The first real chance to get wet doesn’t pop up until Wednesday the 15th. The early part of the week is a write-off, so don’t bother waxing up until then.
Wednesday morning the 15th brings a bit of life with a 5ft SSW groundswell, but it’s a bit average with cross-onshore winds. The afternoon is where it’s at though – the swell jumps to a solid 10ft from the SW, period 15 seconds (long period), and the wind swings to a light cross-offshore. That’s clean, powerful surf. The energy is strong (4215), but this is strictly for the experts – over 8ft and it’s a serious paddle. Long Beach is a sandbar, so that long period might make it a bit straight, but with that offshore breeze, it’ll be a proper session for those who can handle it.
Thursday the 16th hangs in there with 8ft SW swell, but it’s a bit more mixed with cross-shore winds. Not as clean as Wednesday. Friday and Saturday the 17th and 18th drop off in quality, with wind picking up and the swell fading. The 18th is pretty poor.
Sunday the 19th is a standout. The morning has a 7ft WSW swell at 12 seconds, and the wind is light offshore from the S. That’s clean, glassy conditions. The energy is solid (1485) and the report says “very good surf conditions.” Crowds are listed as “often” at Long Beach, so expect company, but with that light offshore, it’s worth the crowd. The afternoon stays clean with a moderate offshore, same swell size.
The next week stays interesting. On Tuesday the 21st, we get another powerful pulse – 10ft SSW swell, 16-second period, light offshore wind. That’s a massive, clean groundswell, energy is a whopping 4870. Again, experts only at that size. Then Wednesday the 22nd is blown out by strong onshore winds, so skip that.
But look at Thursday the 23rd – the afternoon turns glassy with a 13ft WSW swell at 13 seconds. The wind is dead calm, glass. That’s as clean as it gets, but that’s a huge wave, only for the very experienced. The energy is extreme (5686).
The final weekend, the 25th and 26th, has some solid SW swell (8ft to 12ft) but with cross-offshore winds and a bit of chop. It’s not the cleanest, but still has power.
The best bet overall? Sunday the 19th morning is the pick for a good, clean session that’s accessible to intermediate surfers, with that 7ft SW swell and glassy offshore wind. For the experts, Thursday the 23rd afternoon is the absolute standout with huge, glassy 13ft waves. That’s the one to circle on the calendar.
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.
