Fact: Visiting Gozo is a must and even more so, visit the gorgeous Azure Window as it will eventually disappear, some say within 10 years.
In terms of climate, Malta is typically "Mediterranean" in that it enjoys long, hot dry summers (typically April-September) with the vast majority of the annual rainfall received in the period from October through to March.
Unlike the exposed British Isles, Malta's climate is quite predictable with the mean temperature year round being a very respectable 18C. In the depths of winter, the monthly average is 12C (but very rarely dropping below 10C in the daytime) and at the height of summer it averages a sweltering 31C. Given this favourable climate, Malta is very much a year round destination although most tourists choose to visit during the long summer months.
Humidity is high in Malta and rarely drops below 40%. This means that in the summertime it can be quite sticky and nights can be unpleasant. Fortunately almost every hotel in Malta comes with air-conditioning as standard ensuring a good night's sleep for most visitors to the islands.
Summer is usually hot and dry and temperatures can reach the low 40s on occasions. This dryness is exacerbated at times due to the effect of the hot dry "sirocco" wind that sometimes blows up from North Africa.
Due to its pleasant, warm Mediterranean climate mixed with its unique location and prevailing winds, Malta is fortunate to be able to produce much of the fine fare associated with the Mediterranean. Maltese olives are considered by many as some of the finest in the region and Maltese wines (made from the sun kissed grapes of Gozo's vineyards) are gaining wider recognition for their robust flavours. Sun dried tomatoes are also widely produced and eaten or made into paste.
In short, Malta offers a pleasant and predictable climate, ideally suited to the Bristish holidaymaker.
