Cala Bona Weather: Cala Millor and Sa Coma Month by Month

The east coast of Mallorca has a warm, settled summer and a cool but rarely cold winter. Average highs climb from 16°C in January and February to 32°C in July and 31°C in August, with night-time lows of 23°C in high summer and 8°C in the depths of winter. That is the Cala Millor weather in a sentence: hot and mostly dry from June to August, pleasant in spring and autumn, mild and greener in winter.

Rain is less predictable than the temperatures. February is the wettest month by volume at around 95 mm, yet May has the most wet days, twelve on average, because showers there tend to be lighter and more frequent. July is the driest, with about 5 mm across two days. Sea temperatures are not part of the climate record we hold for this stretch of coast, so check the live forecast above if water temperature matters for your dates.

The best months in the data are April, August and November, while January, February, March, May, June, September, October and December count as shoulder months.

January brings highs of 16°C, lows of 8°C and nine wet days, and February is just as cool but wetter, with about 95 mm of rain spread over seven days. March warms to 19°C and is one of the drier months at 26 mm. April reaches 21°C with seven wet days and is one of the best months for walking along the bay or out to Punta de n'Amer. May climbs to 23°C but averages twelve rainy days, so expect the odd shower.

June is where summer begins properly at 28°C, and July is the peak: 32°C highs, 23°C lows and almost no rain. August is barely cooler at 31°C, with five wet days that often arrive as short bursts. September eases to 27°C with ten rainy days, and October holds a warm 25°C. November drops to a comfortable 21°C, another of the best months, before December settles at 17°C with six wet days.

School holidays fall in the hottest weeks, and package prices generally rise with demand then. Anyone checking a 14-day or 25-day outlook for Cala Bona ahead of a summer trip can expect heat rather than rain to be the main story; in the shoulder months, keep an eye on the weather forecast for Cala Millor in the final days before you fly.

For June to September, light cotton and linen, a sun hat, high-factor sun cream and something to cover up on the beach at midday are the essentials, with highs between 27°C and 32°C. Evenings stay warm enough in July and August, when lows sit around 23°C, that a light layer is usually all you need. Bring a compact umbrella for September, which averages ten wet days.

In spring and autumn, from March to May and October to November, pack for days in the low to mid 20s and cooler evenings in the low to mid teens: a fleece or light jacket, comfortable shoes for coastal paths and a waterproof, particularly for May. Winter visitors from December to February should bring proper layers and a rain jacket, as highs hover around 16°C to 17°C and nights fall to 8°C.

The climate averages on this page are recorded at Alcúdia, around 19 miles up the coast, so treat them as a guide to the area rather than a reading taken on the sand at Cala Millor. Cala Millor, Cala Bona, Sa Coma and Son Servera, about 2 miles away, sit close together on the same stretch of coast, and the record we hold does not separate them.
