This reanalysis combines a variety of wide-area measurements in a state-of-the-art global meteorological model to reconstruct the hourly history of weather throughout the world on a 50-kilometer grid. Please note that each source's contribution is adjusted for elevation and the relative change present in the MERRA-2 data.Īll data relating to the Sun's position (e.g., sunrise and sunset) are computed using astronomical formulas from the book, Astronomical Algorithms 2nd Edition, by Jean Meeus.Īll other weather data, including cloud cover, precipitation, wind speed and direction, and solar flux, come from NASA's MERRA-2 Modern-Era Retrospective Analysis. To get a sense of how much these sources agree with each other, you can view a comparison of Valletta and the stations that contribute to our estimates of its temperature history and climate. LMML, 98% 4 mi, 154 ft LICO, 2% 64 mi, 23 ft © OpenStreetMap contributors Cozzo Spadaro (LICO, 1.9%, 64 mi, northeast, 23 ft elevation change).Malta International Airport (LMML, 98%, 3.6 mi, southwest, 154 ft elevation change).The stations contributing to this reconstruction are: The estimated value at Valletta is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Valletta and a given station. There are 2 weather stations near enough to contribute to our estimation of the temperature and dew point in Valletta.įor each station, the records are corrected for the elevation difference between that station and Valletta according to the International Standard Atmosphere, and by the relative change present in the MERRA-2 satellite-era reanalysis between the two locations. Here are the average temperatures.This report illustrates the typical weather in Valletta, based on a statistical analysis of historical hourly weather reports and model reconstructions from Januto December 31, 2016. In the capital, Valletta, the average temperature ranges from 12.5 ☌ (54.5 ☏) in February to 27.5 ☌ (81.5 ☏) in August. In October, the temperature is still pleasant, with highs around 25 ☌ (77 ☏). In September, there's still summer-like weather, especially in the first half usually, the first disturbances arrive at the end of the month, accompanied by thunderstorms. In autumn, the temperature is initially high, and then gradually decreases. Summer, from June to August, is hot and sunny.Įven if the breezes blow, the humidity often makes the heat uncomfortable.įurthermore, the wind from Africa can bring very hot periods, in which the temperature can reach or exceed 40 ☌ (104 ☏). This wind blows more frequently in spring and autumn, and is able to raise the temperature by several degrees. Sometimes, the Maltese archipelago can be affected by the Sirocco, a hot, dry wind blowing from the Saharan desert, often accompanied by dust or sand. The sun shines more and more unchallenged. The rains become less and less frequent, and as early as in April, they begin to be rare. In spring, the temperature gradually rises. However, in December 2014, a light snowfall was observed in some areas, especially in Dingli, in the highest part of the island, at 235 meters (770 feet). The last snowfall occurred in January 1962. ![]() The temperature almost never drops below freezing: at the airport, it dropped to 1/2 ☌ (34/36 ☏) in the coldest winters, although in the center of the island, it dropped to -1.5 ☌ (29 ☏) in 1962. On the coldest nights of the year, the temperature typically drops to 4/5 ☌ (39/41 ☏). In this season, sunny periods alternate with periods of bad weather, with rain and wind.Ĭold days are rare: at most, there may be some days with highs of 9/10 ☌ (48/50 ☏). Winter, from December to February, is mild, and the daily temperature range is limited. ![]() ![]() Malta is an archipelago located in the center of the Mediterranean Sea, consisting of three main islands, Malta (Malta), Gozo (Ghawdex) and Comino (Kemmuna), as well as some uninhabited islands. In the other months, the rains are scarce, and in summer it almost never rains. The rains are concentrated in the period September-March, with a maximum from October to January. In Malta, there is a Mediterranean climate, with mild, rainy winters and hot, sunny summers.
