Why Andorra's seasons matter.
Three things make timing in Andorra consequential. First, the country is essentially defined by its mountain location, the entire territory sits between 838 meters (lowest valley) and 2,942 meters (Coma Pedrosa, the highest peak). Andorra la Vella at 1,023 meters has a continental Pyrenean climate with hot summers (26 °C July daytime), cold winters (-2 °C January overnight, with -10 °C cold snaps not unusual), and reliable snow at altitude December through March or early April. The high country (above 2,000 meters) holds snow from November through May, with the highest peaks holding snow into June. Second, Andorra has two completely different tourism economies based on season. The ski season runs from late November or early December through early April, with peak conditions in February and the busiest tourism period from December 26 through January 6 (with French and Spanish school holidays driving demand). Hotel prices are highest at Christmas, New Year, and February school weeks. The summer hiking and outdoor season runs from late May through early October, with peak conditions in July and August (when high-altitude trails are reliably snow-free). The country becomes much quieter in early November (between hiking season end and ski season start) and again in late April through mid-May (post-ski, pre-hiking). Third, several of Andorra's iconic cultural moments are calendar-locked. Sant Jordi on April 23, the Catalan patron saint celebration with book-and-rose tradition (men give women a rose, women give men a book), is widely observed across Andorra. Sant Joan on June 23–24, the midsummer celebration with bonfires across the country and the descent of the Falla (flaming torches) from the Pic du Canigó on the French side, is a deeply Catalan tradition. Festa Major in Andorra la Vella in early August (typically the first weekend) is the capital's biggest summer celebration. Constitution Day on March 14 marks the 1993 modern constitution. National Day on September 8 is the Verge de Meritxell day, the country's main national patron saint.
