The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s on the table for Laniakea over the next couple of weeks.
Right now, we’re in a bit of a flat spell. There’s really nothing worth paddling out for at the moment. The water temp is running 69°, which is much warmer than normal for this time of year, so if you just want a float, that’s your silver lining. But for actual waves, we’ve got a long gap ahead.
The first real pulse of swell shows up on Friday the 28th of August. It’s a solid SW groundswell, pushing 6 ft with a 16-second period – that’s proper energy. The problem is the wind. It’s cross-onshore from the S at 9 mph, making things fairly choppy. The wave comment calls it marginal, and I’m not hyped on it. Saturday the 29th is similar: 6 ft SW at 14 seconds, but again that cross-onshore wind keeps it messy. Not a standout.
Sunday the 30th drops a little, 5 ft SW at 13 seconds, but the wind swings more cross-shore. Still not clean enough to get excited about. Monday the 31st fades to 4 ft and the chop is back.
Then we hit a bit of a lull for a few days with tiny, poor-condition surf. It picks up again briefly on Thursday the 3rd of September – 4 ft SW at a long 17 seconds with light cross-onshore wind. The period is nice, but the height and wind hold it back. That one gets the highest score in the bunch, but it’s still not a proper standout.
Now, here’s the best window: Tuesday the 8th of September morning. We’ve got 4 ft of SW swell, but it’s running with an 18-second period. That’s a very long-period groundswell, and the wind is light cross-onshore from the SSW at only 6 mph. For a reef like Laniakea, the long period means groomed lines, with clean faces and long lulls between sets. The breaks are going to shape up nicely. That’s your best bet in this entire outlook – a real gem tucked in the second week. Later that afternoon and into Wednesday the 9th, the swell holds around 5 ft with a 16-second period, but the wind stays light, so the quality will still be there, just not *quite* as good.
After that, the swell starts dropping again and the wind picks up, so the run from the 10th into the 11th is mostly junk.
To sum it up: we’ve got a long, flat start. The second week offers the only real promise, with Tuesday the 8th of September being the best on offer for clean, lined-up waves at Laniakea. It’s not a firing forecast, but there’s a window if you’re patient.
Stay frothy.
Rusty.

Information about the Laniakea Surf forecast
The above surf forecast table for Laniakea provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Laniakea can be found by selecting the local surf guide option on the grey menu. Our Laniakea 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 (Laniakea) 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 Laniakea 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.
Laniakea is 5 km (3 miles) from the city of Lima. If you plan a holiday in Lima, look for hotels and other accommodation in Lima. Lima has rooms for a wide range of budgets as well as car hire and transport links.
