January is known to be the windiest time in Malta's weather cycle. The gale force winds however, can be felt as early as December, and as late as March. Rainfall is almost non-existent in the summer months, but in the winter, Malta receives almost all of its annual rainfall. Because of this, Malta weather, especially between the period October and December, can see considerable rainfall and those last few months of the year can bring nearly 51% of all of the winter rain.
Don't let the threat of rain stop you from considering Malta's winter months as an ideal vacation getaway, however. The yearly averages range from 14.6 mm to 222.6 mm (.5 to 8.7 inches), which can hardly be considered a deluge. At its rainiest, Malta's weather still has plenty of beautiful days, and the temperatures in the "coldest" parts of winter are still balmy and comfortable for exploring the many sights to see on land.
For the water lover, spring and fall can be the best times to head out to the Mediterranean coastlines of Malta. The crystal blue water and beautiful beaches are bathed in a comfortable sunlight, and soothing ocean breezes make it the best time of year to enjoy outdoor sports and sunbathing. The winter months of January and February are normally too cold for comfortable swimming, but there are still plenty of people who enjoy the water around Malta even as late as December, and as early as April. The peak of summer, generally from May through October, is when Malta's weather is ideal for beach trips, and these are the busiest times in Malta.
One of the great luxuries in the Mediterranean is the fact that once summer begins, it begins in earnest. There aren't any patchy days of clouds and rain. When summer comes to Malta's weather, it is there to stay, and visitors will be greeted by endless days of cloudless skies and warm sunshine.
July and August are the hottest and most humid months. These can be trying days for anyone with trouble with extreme heat. Businesses in Malta usually close down during the middle part of the day when the temperatures are at their highest, and the local people have learned to adapt to the weather in Malta and make the best use of their time. This is the time when Malta's outdoor culture really pops into action. Tourists and locals alike head to the water for relaxation and to cool off in the warm sea.
Afternoon siestas are commonplace in the hottest months. As the weather cools a little bit in September, however, there is the perfect combination for outdoor enjoyment. The sea is still plenty warm to enjoy days of swimming, snorkeling and boating, while the air is cool enough to allow for all day treks through the amazing cities and towns that have existed since 5200 BC.
