08Editor's notes
What the numbers don't tell you
May is Prague's showcase month, with the Prague Spring festival opening on 12 May with Smetana's Má vlast, the Marathon in the first week, public holidays on 1 and 8 May and the city's gardens in full bloom. Afternoons average 19 °C and days are long. It is peak season for a reason, so book hotels and concerts early. The Charles Bridge is busy from mid-morning; dawn is the quiet hour.
Rain falls on about nine days, often as a late-afternoon storm. The beer gardens at Letná and the river beaches at Náplavka are where the city spends its evenings. The Prague Fringe begins at the end of the month. For the longest days and the United Islands festival at summer prices, see June; the second half of May after the holidays is the better-value window.
