The Lowdown
G'day, Rusty again. Here's the same outlook in feet and Fahrenheit for our crew that thinks in inches.
Right now, we’re in a slow patch at Puertecillo. The first few days are a bust. Thursday the 20th has a 5 ft swell from the WSW, but cross-shore winds and a chop make it a no-go. Combined energy is weak at 941.
Friday the 21st stays marginal. Morning swell drops to 4 ft, afternoon bumps to about 6 ft but with a short period of 8 seconds. Winds are cross-off, so the surface is clean, but the energy is still low (665 and 663). Not a standout.
The weekend into early next week is meh. Saturday the 22nd and Sunday the 23rd have small, weak SW swells under 5 ft with periods down to 7 seconds. Winds are onshore or cross, and energy is in the 260 to 440 range. Not worth getting wet.
Now for the good stuff. Tuesday morning the 25th of August: glassy calm with a 2 ft WSW swell but a beautiful 15-second period. Combined energy is low (346), but that long period will give you real shape on the point. Clean and small, but quality.
The real standout hits Wednesday morning the 26th of August. Swell jumps to 6 ft from the WSW with a 12-second period, and combined energy climbs to a strong 1033. Winds are light offshore from the SE, making for clean faces. This is the best session for experienced surfers – get out there.
Thursday the 27th brings more size: 8 ft in the morning, then a whopping 10 ft in the afternoon with a massive 17-second period and energy at 5916. That’s a heavy groundswell – too big for beginners and only for experts. Cross-onshore wind will make it lumpy. The point might offer some shelter, but expect big lines.
Friday the 28th stays big and messy with rain and thunderstorms. Swell is 8 ft from the WSW with moderate cross-shore winds. Not clean.
Saturday the 29th of August morning: glassy again with 8 ft WSW swell and a 13-second period (energy at 2415). This is excellent for experienced surfers – big and clean. That’s the second standout.
From the 30th onward, the swell fades. The 30th and 31st are marginal to poor with fresh cross-winds. By 1st September, size drops below 3 ft with fresh winds and poor conditions. Not worth it.
Puertecillo is an exposed point that loves a WSW swell, fitting the optimum direction. It’s consistent and sometimes crowded. The standouts are Wednesday the 26th (6 ft, offshore, clean) and Saturday the 29th (8 ft, glassy, big) – both for experienced surfers.
Water temperature is about 56°F, which is normal for this time of year.
Signing off.
Rusty.

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