What September in Shetland is actually like

Expect rain on roughly 54% of days, usually passing rather than persistent, and about 13 hours of daylight to spend outside. Crowds are almost empty this month, and a 5-night trip from Tallinn works out at around €1,190 including flights, a mid-range stay and everyday spending.
