The Lowdown
Alright, Rusty here, looking at Las Urracas for the next couple of weeks. Gotta be straight with you – the first week is a bit of a slow-burner, but if you’ve got patience, the second half of this run is where it gets real interesting.
Right now, Thursday the 20th, the water is sitting at 66°F with an anomaly of 4°F, which is much warmer than normal for this time of year. That’s a nice surprise, but the surf isn’t matching the warmth. We’ve got a weak 3ft to 3ft SW swell, but it’s onshore and the combined energy is only 544, so it’s pretty weak. The tide is messing with things too. Honestly, not worth paddling out for.
Friday the 21st looks a little better. The swell drops to 2ft in the morning, but it’s glassy with a light WSW wind, and the period is a solid 13 seconds. That’s a long-period groundswell, so it’ll have some punch for its size, but it’s still small. The combined energy is 270, so it’s weak. Afternoon picks up to 3ft SW with an 8-second period, but it’s still glassy. It’s surfable, but don’t expect fireworks.
Saturday the 22nd is a mixed bag. Morning has a 3ft SW swell with a north wind that’s cross-offshore, keeping it clean, but the energy is low at 191. The afternoon shifts to a 3ft SSW swell, glassy, but again, the energy is only 186. It’s ordinary, but you could get a few if you’re desperate.
From Sunday the 23rd all the way through Tuesday the 27th, things get pretty grim. The swell drops even smaller, the winds turn cross-onshore, and the energy falls into the double digits or low 100s. It’s a long stretch of poor conditions. You’re looking at a solid 5-day gap of nothing good.
Now, here’s where it gets interesting. Wednesday the 26th sees a real turnaround. Morning and afternoon both have a glassy 2ft to 2ft SSW swell with a 12 to 14-second period, and the combined energy climbs to 279. It’s clean, but still small.
The standout starts on Thursday the 27th afternoon. The swell jumps to 3ft from the WSW, period 13 seconds, glassy, and the combined energy hits 549. That’s a moderate, punchy groundswell with clean conditions. But the real magic is Friday the 28th. Morning brings a 6ft WSW swell with a 17-second period – that’s very long period groundswell, and the energy is a massive 2096. Winds are glassy. This is excellent for experienced surfers. The afternoon swells even more to 7ft WSW, 16-second period, and a combined energy of 2769. That’s strong wave energy. This is expert territory, and it’s gonna be a freight train on the reef. Las Urracas is a reef break, so that long period should be beautiful, but it will be powerful.
Saturday the 29th keeps the energy high. Morning is 8ft SW, 14 seconds, glassy, with a combined energy of 2423. That’s still strong and excellent for experienced surfers. The afternoon gets a bit onshore, but the size is still there at 8ft. The energy drops off a bit after that, but Sunday the 30th and Monday the 31st still have 5ft to 7ft SW swell, though the winds turn onshore and cross-onshore, making it more marginal.
The first week of September sees a return to cleaner, smaller conditions. Tuesday the 1st is a 4ft SW swell, glassy, combined energy 399. Wednesday the 2nd is the real highlight here: 3ft SW swell in the morning with an 18-second period, combined energy 694, glassy. That’s very clean, long-period groundswell. The afternoon is 4ft SW, 17 seconds, energy 800. It’s good, but not the monster of the week before.
So, the absolute best on offer is Friday the 28th of August. That 7ft, 16-second WSW groundswell with glassy winds at Las Urracas is a proper session for experienced surfers. The second best is Wednesday the 2nd of September for cleaner, smaller conditions with that very long period.
The later days from Thursday the 3rd of September onwards have a bit more size and energy, but the winds turn onshore, so it’s more of a power session than a clean one.
Rusty.

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