Malta has a typical Med climate with more than a few surprising quirks, most of them surprising in a good way. As an island archipelago, it is heavily influenced by the weather of the sea. Bathing is possible even during the winter months (although it may get a little chilly in the darkest depths of the year) and it has a below average rainfall for the region. The Sirocco winds from Africa bring a toasty heat to Malta in the spring and autumn- and occasionally Saharan sands, which spread across Europe and travel as far northwest as the UK, surprising British motorists who leave for work one morning or two every year or so to see their cars peppered with the sands. True story!
Local currency in Malta is the euro, with banks open morning and afternoon. However, you can find various bureaux de change open 24-7.
If you’re going to rent a car to do some exploring, you should note that driving is on the left side of the road in Malta. Speed limits are between 50 and 80 km per hour in Malta, depending on whether you are in a built up area or on the open road. You’ll probably require your full national or international driving licence to drive on the islands, and comprehensive insurance is a very good idea too. Note that if you’re going to go a little cheaper and rent a moped or a similar vehicle to do your exploring, some of Malta’s roads are not as welcoming to those with two wheels as against those on four. Certain routes will not permit smaller vehicles.
There are some small electric taxis on the islands that are an attractive way to get around. It’s a high tech version of the rickshaw.
