What the numbers don't tell you
May is warm, sunny and busy, with afternoons around 22 °C, Primavera Sound at the Parc del Fòrum at the end of the month or start of June, beach bars open and Labour Day on 1 May closing shops. Sea temperatures reach the point where locals begin swimming, around 18 °C. Hotels are at spring peak pricing during the festival week.
Rain falls on about five days. The Nit dels Museus in mid-May opens the museums free until one in the morning. The Montjuïc cable car and the beaches are busy at weekends. Whit Monday is a holiday in Barcelona in some years. For the beach summer and Sant Joan's bonfires, see June; the second half of May before Primavera Sound is the sweet spot.
