The average summer temperature from July to September is around 25º with highs reaching 30º C, giving up to 11 hours of sunshine a day. This doesn’t drop much below 7º C in the cooler winter months. With an average annual temperature of around 16º / 17º C, this makes Menorca a very pleasant place to live as it is neither too hot nor excessively cold.
In spring, Menorca blooms with meadows of blue cornflowers, yellow marguerites and bright red poppies. However, from November through to February, the island becomes cooler with more rain falling especially inland on the higher ground. In March, Menorca is particularly affected by the famous ‘tramontana’, a prevailing and often strong northerly wind which contributes to the island being given its name the ‘windy island’.
There are in fact names for all eight winds that make their presence felt on Menorca (depending on their direction) and turbines have been built near Mahon at Milà to capture wind as a renewable source of energy. This was the first wind farm in the Balearic Islands and there are proposals for up to four more sites.
Menorca is also the wettest and the coolest of the Balearic islands as it lies further north and further out to sea than the other islands. Rainfall varies widely, with very little falling during the summer and considerably more in autumn and winter. This varies by region, with an average of about 450mm in the south-east and 650mm in the interior and north-east, resulting in a lush green landscape for most of the year. The maximum seasonal rainfall is in the autumn and October is usually the wettest month.
Sea temperatures in Menorca range between 15º C in February and 25º C at the end of August.
