Map from Google - Andorra

Andorra, a small mountainous country located in the Pyrenees, between France and Spain, has a temperate climate in the lower valleys, and a mountain climate at high altitudes. Precipitation is quite frequent, since the Atlantic frontal systems affect the country for many months a year, while in summer, when the anticyclone prevail, thunderstorms can break out in the afternoon.

The capital, Andorra la Vella, is located at 3,300 feet above sea level, in the Valira Valley, in the low part of the country (the lowest point is Sant Julia de Loria, 2,755 feet, in the south, near the border with Spain). Here the climate is not too cold: the average temperature in January is 36.5 °F, while in July and August it's 66 °F. Winter is cold but not freezing, although the night temperatures drop quite often a few degrees below freezing. The winds from the north take on foehn characteristics, that is of a warm, dry wind that descends from the mountains. However, heavy snowfalls and frosts may occasionally occur.
Summer is quite warm during the day, with highs around 77 °F, but the relative humidity is not high, and the nights are cool. In the afternoon, thunderstorms may occur.

When to go

The best time to visit Andorra runs from June to mid-September, being the least cold in the mountains, and being warm (but not too much) in the valleys. You should be equipped for the cool at night (or the cold at high altitudes), even in the valley floor, and for the afternoon thunderstorms. July and August are the warmest months; July is generally less prone to thunderstorms than August.

What to pack

In winter: warm clothing, sweater, down jacket, hat and gloves.
In summer: light clothes, T-shirts, but also long pants, jacket and sweater for the evening and the mountains; hiking shoes, sunscreen and sunglasses, raincoat or umbrella.
