Weather in Cala d'Or: forecast, coves and monthly averages

1Forecast for Cala d'Or and beach reports for nearby coves

For Cala d'Or the page calls up the MET Norway forecast. Behind it, the service's documentation says, is the ECMWF model, which splits Mallorca into cells of about 9 km and runs out to the tenth day.

On a 9 km grid Cala d'Or, Porto Petro and Cala Ferrera sit in practically the same cell, and the table shows almost identical values for them. The Wind column gives a strength but no direction.

If you want more detail for a beach day: AEMET runs beach forecasts for two neighbouring coves, Cala Mondragó 4.4 km south-west and Cala Marçal 5.1 km north-east in a straight line. For morning and afternoon, today and the next two days, they list waves, UV index, water temperature, sky and wind strength. Why no forecast holds beyond day 10 is covered on the Mallorca 16-day page.

2The coves of Cala d'Or: from Cala Egos to Cala Ferrera

According to the Spanish Wikipedia Cala d'Or has coves of white sand with narrow entrances and rock walls. The Catalan Wikipedia lists them from south to north:

• Cala Egos is the southernmost, linked by road to Porto Petro.
• Cala Llonga is the longest and holds the harbour, so swimming there is not possible.
• Cala Petita lies between Cala Llonga and Cala Gran and is also called Cala d'Or.
• Cala Gran is the largest sandy cove in the resort.
• Cala Esmeralda is the trade name of Caló dels Corrals, the last cove in the municipality of Santanyí.
• Cala Ferrera is the first cove of Felanitx.

On the map the coves open to the south-east. Wind from that side hits the entrances head-on, while a northerly arrives over land. That is a reading of the map, not a measurement.

3Harbour, Fortí and townscape of Cala d'Or

According to the Spanish Wikipedia the Cala d'Or marina was built in 1969 in the natural inlet of Cala Llonga. It consists of Port Petit and Porto Carí and has room for about 500 boats under 20 m in length.

At the mouth of Cala Llonga stands the Fortí, a fortification of 1730, rebuilt in 1793, for a garrison of twenty men. The Catalan Wikipedia says it now houses a small museum.

The resort itself was begun in 1933 by Josep Costa Ferrer, who came from Ibiza. The name goes back to the cove of Cala d'Hort on Ibiza. The white, flat-roofed houses in Ibiza style are still required by a local bylaw, according to the Spanish Wikipedia.

4Climate in Cala d'Or: dry May, warm August nights, mild February

Month by month, the table shows what the Portocolom station measured on average between 2011 and 2025.

Averages of past years, not a forecast. Station: Portocolom (AEMET B434X). Fuente: AEMET. Years with complete data per month: 11 to 15. Sea: NOAA OISST v2.1, open sea.

May in Cala d'Or is a dry early-summer month with 31.9 mm over 3.6 rain days, days of 22.5 °C and nights of 14.7 °C. Anyone planning to swim in May finds fresh water at 18.6 °C.

In August the night, at 22.3 °C, sits barely eight degrees below the day at 30.2 °C.

In winter February stands out: the night-time average only drops to 8.3 °C, far less than at the Muro, s'Albufera station in the north, and the day reaches 15.8 °C with 45.7 mm of rain.

The wettest of the well-covered months is October, with 64.4 mm over 4.9 rain days, more than May and August combined. More on May across Mallorca: Mallorca weather in May.

5How warm the sea off Cala d'Or gets

Between May and July the sea off Cala d'Or gains seven degrees, from 18.6 °C in May through 22.5 °C in June to 25.6 °C in July. August brings the warmest water of the year at 26.8 °C, with September next at 25.9 °C.

Autumn gives up the warmth reluctantly, with 23.5 °C in October and 20.2 °C in November. The water bottoms out in February at 14.5 °C, after 15.4 °C in January.

The values come from the NOAA OISST v2.1 satellite analysis on a 0.25 degree grid, for an open-sea cell centred on 39.375 N and 3.375 E, 12.5 km east of Cala d'Or. In shallow, narrow coves the water can differ from the open sea. A comparison with the north, west and south coasts is on the Mallorca sea temperature page.

6Porto Petro, Calonge and Portocolom: neighbours of Cala d'Or

Cala Egos, the southernmost cove of Cala d'Or, runs by road straight into Porto Petro, according to the Catalan Wikipedia. The same article gives 3 km on the Ma-4013 to the inland village of Calonge.

For air and rain this page uses the AEMET station B434X Portocolom, 17 m above the sea, 6.0 km north-east of Cala d'Or. The nearest coastal page with monthly averages is Sa Coma on the east coast, with Cala Millor further north.

The station has gaps, so the number of years matters here. February, May and the August temperature rest on all 15 years from 2011 to 2025, as do the October rain and the sea outside December. The August rain, used in the text only in the comparison with October, rests on 14 years. For March, June, September, November and December only 11 to 13 years of air and rain data are available, so the text does not quote those values. Days with 1 mm or more count as rain days.
