The Lowdown

G’day, I’m Rusty, and I’ve been watching this stretch of coast like a hawk. Right now, we’ve got a solid run of swell on the cards, but it’s a mixed bag of conditions. The water temp’s sitting at 56°, which is about what you’d expect for this time of year—nothing weird there.

The standout is La Boquilla (river mouth). Monday morning, August 3rd, is your golden ticket. We’ve got a solid 7ft swell from the west, with a 12-second period, and the wind is glassy—hardly a breath of air. That means the waves will be clean and well-shaped. The combined swell energy is pumping at 1448, so there’s plenty of power. This is excellent for experienced surfers, but beginners might find it a bit much. The break is very consistent, and it’s exposed to the swell, so you’ll get plenty of sets. The offshore wind direction is east, which is ideal for this spot. Crowds are possible on a Monday morning, but it’s likely to be manageable.

Monday afternoon, August 3rd, is also a beauty, with 7ft west swell and glassy winds from the west-northwest. The energy is similar at 1452. It’s a repeat of the morning’s quality.

Now, we do have a gap from the start, but the first proper surf is on Sunday afternoon, August 2nd, with 10ft west swell and 12-second period, offshores at 6 mph. The energy is massive at 2380, but the swell is too big for this break—it’s only for experts. The forecast says “wind and tide favorable,” but the size overpowers everything.

Tuesday, August 4th, is a write-off with cross-shore winds and choppy conditions. The swell drops to 7ft and 6ft, but the wind turns it messy.

Wednesday, August 5th, still has cross-onshore winds, but the swell bumps up to 8ft from the west-southwest with a 14-second period, giving us 2175 energy. The wind is light, so it’s not all bad, but the quality is marginal.

Thursday, August 6th, is poor—moderate rain and cross-onshore winds with a 6ft to 8ft swell. Not worth paddling out.

Friday, August 7th, the swell drops to 4ft and 3ft, with cross-onshore winds. The energy is around 646 to 660. It’s small and weak.

Saturday, August 8th, morning sees a bit of hope with 6ft from the southwest, offshores at 6 mph, and clean conditions. The energy is 1167. It’s good for experienced surfers, but the afternoon turns cross-shore and windy.

Sunday, August 9th, is back to huge 10ft swell from the southwest, but the wind is strong and cross-shore, making it lumpy. The energy is over 3000. This is for experts only, and even then, it’s a challenge.

Monday, August 10th, morning has 7ft from the southwest with a 13-second period, cross-offshore winds, and clean conditions. The energy is 1619. It’s excellent for experienced surfers, but the afternoon gets cross-shore and windy.

The rest of the week into the second week—from Tuesday, August 11th, through to Saturday, August 17th—the swell lingers between 4ft and 8ft, mostly from the west-southwest, but the winds are often cross-shore or cross-onshore, keeping the quality marginal. The best of the second week is Friday morning, August 14th, with 4ft west-southwest swell, 14-second period, cross-offshore winds, and clean conditions. The energy is 592. It’s not huge, but it’s clean. Sunday, August 16th, has a 8ft west-southwest swell with a 15-second period, but the wind is cross-onshore, so it’s messy.

Overall, the first week has the best windows, with Monday, August 3rd, being the pick. The second week is more of a grind, with only a few clean moments. The beach-and-reef setup here can get interesting for kite surfing when the wind picks up and the swell is big, but for paddle surfing, you’ll want to pick your times carefully.

Rusty.

Information about the La Boquilla Surf forecast

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