Tamarindo Surf Forecast and Surf Report

G'day, Rusty here. We’ve got a solid run of surf on the cards for Tamarindo, starting right from Monday morning. The water’s a touch warmer than normal, sitting at 86°, which is a nice little bonus for this time of year.

Monday 31st August kicks things off with a clean 4ft swell ramping up from the SW, pushing through at a long 13 seconds. The NE cross-offshore breeze is light, so the river mouth will be tidy and inviting. The combined energy is moderate (456), enough to get you moving without it being a fight. This is a good, clean start.

Into Tuesday 1st September, the morning glass is back with a 3ft SW swell and a period dropping back to 12 seconds. The E wind goes offshore, and it’s clean again. Another good morning session.

Wednesday 2nd September is a write-off for the morning – only 2ft with a sketchy onshore breeze and a risk of storms. The afternoon is even worse with a choppy cross-onshore. Skip it.

Thursday 3rd September morning is a beauty – absolute glass, 2ft but with a very long 19-second period. The energy is ramping up (756), but that tiny height means it's a small, long-period groundswell. It’s going to be clean and super fun on the point if you’ve got a log.

Friday 4th September is where the week peaks. A 5ft SW swell with a 17-second period combines for strong energy (1462). Glassy conditions in the morning, and the label says it’s excellent for experienced surfers. That’s the standout. The wind is offshore early, so the river mouth will be running clean with proper, chunky lines. It's a little too big for beginners, but for everyone else, this is the session.

Saturday 5th September morning keeps the quality high: 6ft SW groundswell, 16-second period, and absolute glass. With the combined energy hitting 1466, this is serious wave power. Same deal – excellent for experienced surfers, and the biggest swell of the run. The offshore forecast is a dream.

From Sunday 6th through to Wednesday 10th September, the size backs off gradually (5ft down to 3ft) but the quality holds. Mornings are either glassy or clean with cross-offshore winds, and the periods stay long (13-16 seconds). Each morning is a reliable, good-to-very-good option. The energy eventually drops into the moderate range (around 500-700), so it’s still fun but not the power of the weekend.

Thursday 11th September morning brings another sniff of quality: 4ft, 15-second period, clean with a cross-offshore breeze. Still worth a paddle.

The second week sees the swell settle into a quieter, more consistent pattern. Mornings on Saturday 12th through Tuesday 15th offer clean conditions with 3ft to 4ft SW swells, glassy or offshore winds, and periods ranging from 14 to a very long 19 seconds. The energy tails off (down to 212-438), so it’s smaller but very clean – perfect for learning or a longboard session. The Tuesday morning (15th) has a moderate offshore breeze, so expect some nice, lined-up peaks.

Overall, the Friday 4th and Saturday 5th September mornings are the clear standouts. If you can get out then, you’ll score the best combination of size, power, and clean conditions. The rest of the period is punctuated by quality morning windows, but those two days are the real deal.
