2019 to 2025

It's many stages through four regions: the Basque Country, Cantabria, Asturias and Galicia. Here we count, for each one, the warning days in the zones it crosses, and add them up month by month.

April and July are the calmest months. The busiest are November and January, with rain and wind; in June, on the Basque and Cantabrian coasts, storms pick up too.

Heat warnings are uncommon, but over the last eight years most of the route's red days have been for heat, in summer, such as 21 to 24 June 2026. The red days that covered the most stages were for wind: 21 and 22 December 2019.

The EuroVelo 1's warning zones

AEMET doesn't warn by village but by zone. The EuroVelo 1 crosses 10 warning zones, each with its own thresholds and warnings: on the same day one section can have a warning and the next none.

Tips for the EuroVelo 1

Check AEMET's forecast the evening before each stage, and the zone's warnings on the Climaviso map.
A waterproof and windproof layer: rain and wind are the most common warnings. With a wind warning, expect crosswind gusts and headwinds, above all in Galicia.
On hot days, set off early: along the whole route the yellow heat warning starts at 34 °C.
In June, watch for storms on the Basque and Cantabrian coasts: it's one of their busiest months.
A warning covers the whole zone: it doesn't mean it will happen on your stage, but it does mean you should keep an eye out.

Frequently asked questions

What's the best month to ride the EuroVelo 1?

By warnings, April: on average, 0.9 warning days if you ride the 16 stages that month. Then July and May. The month with the most warnings is November, with 3.0 days.

Which section of the EuroVelo 1 gets the most rain warnings?

Basque Country: on average, a rain warning on 9% of days, mostly in June, September and November.

Does the EuroVelo 1 get hot enough for warnings in summer?

In July and August, the section with the most heat warnings is Basque Country: a heat warning on 6% of days, on average.

Can it snow on the EuroVelo 1?

Yes, above all on the mountain sections: snow warnings bunch up in the Bizkaia interior zones, in January, February and November. There, yellow needs 2 cm in 24 hours.

What should I do if there's a warning on my stage?

A yellow warning calls for attention, not cancelling: check the forecast and, in heat, ride first thing. With strong wind, above all crosswind, shorten the stage or wait. With storms, find shelter before the afternoon. With orange or red, follow Civil Protection's advice and don't set off.

This is not a forecast: it counts the warnings AEMET issued on those dates in past years. A warning is a forecast that a threshold will be crossed in the zone, not damage.
