Playa de Seaia Surf Forecast and Surf Report

Alright, Rusty here with the imperial version for you. Let’s break down what’s coming up at Playa de Seaia for the next couple of weeks.

Right from the start, it’s small. The waves are just under 3 feet (0.9m) from the NW, with a period of 8 seconds. The combined energy is weak (119). The water is a touch chilly for midsummer, at 62°, about 2° cooler than the average, so you’ll notice the cold.

Sunday morning (July 12th) is clean and small, with a light cross-off breeze. It's a beginner-friendly 3-foot wave. Sunday afternoon sees the size drop to 2 feet (0.6m) but the wind shifts to a clean offshore from the SW at 19 mph, making it tidy but tiny.

Monday (July 13th) is the real sweet spot. The morning is clean with 3-foot waves from the NNE and a light cross-off. But the afternoon is glassy. No wind. Flat, smooth 3-foot waves from the NNE. This is the pick of the whole forecast for a clean, fun, small-wave session. The energy is moderate (122). For a longboard or a beginner, this is perfect.

Tuesday (July 14th) stays clean and small. The morning is glassy with 3-foot waves from the NNE and a 9-second period, giving them some shape. The afternoon gets a cross-off, but it’s still clean. Energy is moderate (141).

From Wednesday (July 15th) onwards, the surf drops away. The waves shrink to 2 feet (0.5m) and the energy falls to 84. The winds turn cross-onshore and then onshore for days. This leads to a long, dry spell with poor, choppy conditions. The swell stays below 2 feet for several days, and the wind is ugly.

Then, around Monday (July 20th), a new pulse arrives. The energy jumps to 152, with waves at 4 feet (1.2m) from the NNE, but the period is only 5 seconds and the wind is onshore. It’s messy. The next couple of days see a bigger NW swell (3 to 4 feet) but the wind is still cross-onshore or cross-shore. On July 21st afternoon, the energy is high (364), but the quality is marginal. This is more of a kite-surfing setup for the beach break.

The biggest event is on Thursday, July 23rd. The swell jumps to 7 feet (2.0m) from the NW, with a strong energy reading of 530. The period is 8 seconds. By the afternoon, it’s still 6 feet (1.9m) and the energy peaks at 683. The wind is cross-onshore from the N at 10 mph. This is a powerful, solid swell, but that wind will chop it up. This is strictly for experienced surfers only, as the size is well over 5 feet. The swell direction (NW) is a good match, but the wind ruins the party.

After that, the last few days of the forecast show the swell dropping back down, with strong onshore winds (NE up to 22 mph) blowing through the 25th to the 27th of July. The energy is moderate (up to 256), but the conditions are poor. No good options there.

So, the standout is that glassy Monday afternoon (July 13th). It’s not big, but it’s the cleanest, most fun wave you’ll get in this forecast. The big swell on the 23rd is for experts only, and only if you can handle the wind. Otherwise, it’s a waiting game.

Rusty.
