We compare the 7-day forecast to the last 5 years of marine data for the same week at Costa da Caparica. The delta tells you whether conditions are shaping up better, worse, or about the same as a typical early July.
We score each day of the 7-day forecast using the same algorithm as the leaderboard, and highlight the highest scorer.
Open-Meteo's Marine API (swell height, period, water temperature) and Weather API (wind and conditions).
Honestly, no. Every break has tide windows, swell directions and reef contours that a global model cannot see. Treat the score as a starting point, then check a local cam.
The best week for surf at Costa da Caparica is the week of 16 November (score 3/5) with low crowds.
Moderate swell providing fun waves for a session. Short-period wind swell: expect weak, crumbly faces. Heavy offshore making for difficult paddle-outs but textbook faces.
Heads up: jellyfish: peak season.

The air here is 42% cleaner than the average comparison city right now.
Noticeably cleaner air than a typical city. Good conditions for prolonged outdoor activity.
Not a pollutant. Ozone is naturally higher at altitude and near the coast, and lower in cities where traffic exhaust breaks it down. High readings here typically indicate clean air. Can cause short-term airway irritation during intense exercise but is not linked to the long-term health risks of particulate pollution.
Additive health score: each pollutant contributes points relative to its WHO 2021 guideline and long-term health impact (PM2.5 9, NO₂ 5, O₃ 3, PM10 2, SO₂ 1 at WHO limits). Data via Open-Meteo. City markers show live readings. Red line marks the WHO guideline. Updated 03:00

Costa da Caparica is a 30km stretch of beach south of Lisbon, across the Tagus. The beaches face west into the Atlantic and produce consistent surf along their entire length. A mini-railway runs along the coast in summer, accessing different numbered beaches. The northern end is urban; the southern end is wild and natural. It provides Lisbon's most extensive surf options with variety from mellow to powerful.
Picks up any westerly Atlantic swell. A north-easterly wind is offshore. Works on all tides. Consistent year-round. The 2-6ft range suits the various sections. The northern beaches are more sheltered; the southern end is exposed and powerful. Something is always rideable.
The numbered beaches each have different characters. The first beaches (near town) are sheltered and popular. Walking or driving south finds progressively more exposed, powerful waves with fewer people. Choose your beach based on conditions and desired crowd level.
Rip currents on bigger days. The southern beaches can be powerful. Some beaches have limited facilities and mobile signal. Sandy bottom throughout. Lifeguards at the main beaches in summer.
Multiple car parks along the coast road. The mini-railway in summer accesses beaches without a car. Bridge from Lisbon (25 April Bridge) provides easy access. Full facilities at the northern end; basic at the southern end.
Busy at the northern (town) end. Walking or driving south dramatically reduces crowds. The 30km length means empty peaks always exist somewhere. The southern beaches are genuinely empty on many days.
Costa da Caparica rewards exploration. The further south you go, the emptier and more powerful the waves become. The northern beaches are convenient but crowded. Bring a bike or use the railway to access different sections. The fish restaurants along the coast serve some of Lisbon's best seafood at half the price. The sunset facing west across the Atlantic is spectacular.

View Best Time to Go →Combining historical conditions with school holiday crowd pressure to find the sweet spot.
The timing score combines two signals: historical conditions quality (how good the skiing or surfing typically is in a given week, based on 5 years of weather data) and crowd pressure (how many of this destination's feeder markets have school holidays that week).
Crowd pressure is weighted by each feeder country's share of visitors. If 40% of a resort's visitors come from France and France is on holiday, that contributes 0.40 to the crowd pressure score. Crowds can reduce the timing score by up to 35%, ensuring conditions still matter most.
Scores: 5 = great conditions with low crowds (the sweet spot). 4 = great conditions with moderate crowds, or good conditions with low crowds. 3 = average. 2 = below average conditions or very crowded. 1 = poor conditions or peak holiday chaos.
