The Lowdown
Alright folks, Rusty here. Let’s take a good, hard look at what’s coming down the pipe for Buchupureo.
We’ve got a solid run of swell kicking off, with a big pulse of energy from the west-southwest. The water’s sitting at 55°, which is pretty much normal for this time of year, so no surprises there.
The standout window is the next few days. Tuesday morning the 18th is looking special. We’ve got a clean 4ft swell from the WSW at 15 seconds – that’s proper groundswell energy with decent period. The wind is dead calm, glassy as a mirror, and the combined energy is pumping at 1177 (moderate), so there’s plenty of push. This is the pick of the whole forecast. Experienced surfers are going to love it. Just know this spot can get a crew, so you might have some company.
Wednesday morning the 19th is another beauty. The swell jumps to 7ft, still from the WSW, period at 14 seconds, and the wind goes glassy again. That’s a lot of water moving – 1906 (strong) combined energy – so it’s powerful. This is getting into the realm of intermediate to expert territory at that size.
From Thursday the 20th through Sunday the 23rd, the swell stays fun but starts to back off. We’re looking at 6ft to 3ft, with clean cross-off winds and moderate energy in the 700 to 350 range. It’s good, but not the standout. Saturday afternoon the 22nd drops off pretty flat, and Sunday morning the 23rd is small at 3ft, though the period is still long at 13 seconds.
Then we hit a rough patch. Monday the 24th through Sunday the 30th is mostly a write-off. Onshore winds from the north and northwest wreck the surface, turning it choppy and lumpy. There’s a massive swell spike on Wednesday the 26th with 10ft waves from the west, but with a north wind pushing in, it’ll be a messy, crumbly beast – more for the kite crew than a paddle surfer. The energy is huge (2043 and 2987 at times – strong to very strong), but the conditions are just not cooperating.
We do get a little ray of hope on Monday morning the 31st of August. Glassy conditions return with a light 4ft swell from the west, and it’s clean again. The energy is low at 459 (weak), but at least you’ll get a few clean ones.
So, if you’re looking for the absolute best, hit Tuesday morning the 18th or Wednesday morning the 19th. After that, pick your moments, because the back half of this outlook is a battle with the wind.
Rusty.

Information about the Buchupureo Surf forecast
The above surf forecast table for Buchupureo provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Buchupureo can be found by selecting the local surf guide option on the grey menu. Our Buchupureo 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 (Buchupureo) 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 Buchupureo 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.
