The Lowdown
Alright folks, Rusty here. Let’s get stuck into the surf outlook for the next 16 days. We’ve got a solid run of point-break action at Buchupureo, but you’ll need to be picky with your sessions as the winds have a mind of their own.
The overall pattern is a classic Spring setup: a consistent, long-period SW groundswell rolling in, but afternoons get trashed by a cross-shore SW wind. The real magic happens in the mornings when the breeze drops out or turns offshore. The standout window is the first two weeks, with a couple of absolute gems. Expect a few days of flat or poor conditions in the final days, but we’ll break it down.
Starting Tuesday, September 8th, the morning session is a runner. The water is sitting at 57°F, which is a touch warmer than normal for this time of year, so it’s not a total shock to the system. You’ve got a 4ft SW swell (13 sec period) with a light cross-off SSE breeze. The combined energy is moderate at 489, and the waves are clean. It’s not huge, but it’s good. The afternoon is a write-off – that SW wind jumps to 12 mph and turns cross-shore, making it messy.
Wednesday the 9th is the same story. Morning glass-off with a 3ft WSW swell (14 sec) and a light 3 mph SE offshore wind. The energy is 448 – clean, workable, fun. Don’t bother with the arvo.
Thursday the 10th morning is another goer. 4ft SW swell, 13 sec, 3 mph S cross-off. Clean.
Friday the 11th morning is a special one. The wind is glassy, dead calm. It’s a 3ft WSW swell with a 12 sec period and moderate energy at 264. It’s small, but it will be *perfectly* smooth. That’s the kind of morning you call in sick for.
Saturday the 12th morning is a solid session. 5ft SW swell, 8 sec period, which is a shorter period, but with a 9 mph SSE offshore wind, it’ll be clean and punchy. Energy is moderate at 350. This is the best size for intermediates.
Now, the real standout. Sunday, September 13th. This is your best day on offer. The morning has a 2ft SW swell, but the period is a massive 18 seconds – that’s proper groundswell energy. The combined energy is 607 (moderate), and with a light ESE cross-off breeze, it’s going to be clean. This long-period swell will wrap beautifully around the point at Buchupureo. It’s not huge, but the quality will be next level. Expect long, racy walls.
Monday the 14th morning is another beauty. 4ft WSW swell, 14 sec, with a 6 mph SSE offshore wind. The energy is 841 – strong. This is a powerful, clean wave.
Tuesday the 15th: morning is a winner again. 3ft WSW swell, 13 sec, SE offshore at 9 mph. Energy 536. Clean.
Wednesday the 16th morning is glassy again, but a smaller 2ft SW swell with 12 sec. Still good for a grovel on a longboard.
We hit a bit of a lull for a few days. Thursday the 17th morning has a bumpy 5ft SW swell (6 sec) – short period, not great shape. Friday the 18th and Saturday the 19th are very ordinary.
Then, Sunday, September 20th morning is a hidden gem. 5ft WSW swell, 12 sec, with glassy conditions. The energy is 784 (strong). This is a big, clean, powerful morning. The afternoon gets a bit lumpy but still surfable.
Now, the final few days. Monday the 21st sees a rise in size to 8ft, but the wind turns cross-on from the NNE, and the energy jumps to 1773. This is strong, but it’s messy. The surf is big and powerful, but it’s not clean. On the 22nd the swell drops back, but rain and onshore winds ruin it. The 23rd is a complete write-off with 7ft+ onshore slop and 19 mph winds. This setup looks more interesting for kite surfing than paddle surfing.
So, to sum it up: the best windows are the mornings of the 8th through the 16th, with Sunday the 13th and Monday the 14th being the absolute standouts. The final few days are a bust, so don’t hold out hope for the third week.
Rusty out.

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.
Buchupureo is 42 km (26 miles) from Cauquenes. If you plan a holiday in Concepcion, look for hotels and other accommodation in Cauquenes. Cauquenes has rooms for a wide range of budgets as well as car hire and transport links.
