Each location is refreshed once every three hours. The hourly view, 7-day forecast, luck factor and packing notes come from the same stored update.
We compare the 7-day forecast with the version-matched historical observations available for the same time of year at Deba. The delta shows whether conditions look better, worse or about the same as a typical late July.
We score each day of the 7-day forecast using the same algorithm as the leaderboard, and highlight the highest scorer.

Not much swell but keen eyes will find something to ride. Short-period chop. The waves lack any real push. Strong offshore, clean but tough to paddle into. Conditions improving through the afternoon. Not enough swell to get this spot firing properly.

Deba is a powerful, heavy right-hand point break situated in the Basque Country of northern Spain. The wave mechanics are driven by a complex bathymetry featuring a rocky headland, a submerged rock shelf, and the sediment outflow from the Deba River. This structure intercepts massive north-westerly winter groundswells from the Bay of Biscay. The sudden depth transition over the rock and sand matrix forces the wave to pitch intensely, creating a massive, steep drop followed by a thick, powerful carving wall. A southerly offshore wind is required to hold the enormous face open against the coastal currents. Due to the intense hydraulic volume, the precarious rocky take-off zone, and the severe physical demands required to paddle against the river current, Deba is strictly an advanced surfing location. It requires significant large-wave experience and precise positioning to successfully negotiate the powerful initial drop.
Heads up: rocks exposed at low tide, and jellyfish: high.

The air here is 75% 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.

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.

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.
Last 30 days of logged conditions.
