The climate of Mallorca is typically Mediterranean with sunny summer and mild winter. We can say that there are only two seasons on the island: a hot summer that lasts from May to October, and a warm spring (or autumn) from November to April.
May.
The average daily temperature in May is + 23°C, but sometimes might be surprises with heat above +30°C or cold snap to +18°C. In any case, warm clothes still needed in May as nights temperatures are +12+15°C.
June, Julay, August.
For those looking for the sea swimming June is the perfect starting time, because in May the sea does not have enough time to warm up. The strongest heat in Mallorca comes in July and August. Thermometers show +30°С already in the morning, and by noon the air heats up to +35°C.
September.
September perhaps is the best holiday time in Mallorca with children. The period of mass vacations remains behind, the air temperature drops to +26°С, the sea retains the heat accumulated over the summer.
From November to April the temperature in Mallorca drops to +14+19°C. Late autumn, winter, and early spring are rainy times.
