What August in Chamonix is actually like

Expect rain on roughly 45% of days, usually passing rather than persistent, and about 14 hours of daylight to spend outside. Crowds are very busy this month, and a 5-night trip from Tallinn works out at around €1,450 including flights, a mid-range stay and everyday spending.
