We compare the 7-day forecast to the last 5 years of marine data for the same week at Deba. 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.

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 Deba is the week of 16 November (score 3/5) with low crowds.
Small waves but still worth a paddle for keen surfers. Short-period wind swell: expect weak, crumbly faces. Onshore chop spoiling the lineup. Best conditions early morning before the sea breeze arrives. Not enough swell to get this spot firing properly.
Heads up: jellyfish: peak season, and rocks exposed at low tide.

The air here is 85% cleaner than the average comparison city right now.
Significantly cleaner air than a typical city. Ideal for outdoor exercise with minimal respiratory strain.
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

Deba is a powerful right-hand point break on the Basque coast of northern Spain, where a rocky headland creates a defined, mechanical wave. The wave wraps around the point and peels along a rocky shelf, offering long rides when conditions align. The town sits above with colourful buildings and a harbour. On bigger swells, the right-hander can run for 100+ metres with barrel sections.
Needs a solid north-westerly groundswell wrapping around the headland. A southerly wind is offshore. Best at mid to high tide when water covers the reef. The 4-8ft range produces the best waves. Works October through March most consistently. Smaller swells fail to wrap around the point properly.
The take-off is at the tip of the point where the swell first encounters the headland. The wave then runs right along the rock shelf towards the beach. Position yourself at the boil near the rocks. On bigger days the take-off shifts further out as the swell wraps wider.
Rocky bottom throughout the point break section. Shallow reef at lower tides. Strong currents sweep along the headland on bigger swells. The wave is powerful and fast. Getting caught inside means being dragged across rock. Experienced surfers only on solid days.
Park in town and walk along the harbour wall to the point. Entry from the rocks requires knowledge of the channel. The beach inside the bay offers an easier entry but involves a longer paddle.
A tight local Basque crew who surf this wave regularly. The point break section is competitive on good days. Show respect, do not drop in, and wait your turn. Weekdays are quieter. The lineup has a clear hierarchy.
Study the entry point carefully before your first session. The local surfers enter through a specific channel in the rocks. The right-hander works best on a dropping tide from high to mid. If Deba is too small, Mundaka (30 minutes east) needs even more swell but is world-class when it works.

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.
