Sal is a beautiful island that is part of the Barlavento northern group of islands in Cape Verde. Sal has only one administrative body - the Sal Municipality, with Espargos city as its seat. Sal was discovered in 1460 and remained undeveloped and with minimal inhabitants for almost three centuries, until the discovery of salt in Santa Maria and Pedra de Lume led to further developments which opened up the island to more opportunities. Today, the former salt mines are renowned spots with therapeutic salty water, visited by people from far and wide. Other tourist attractions include the attractive lake within a desert environment at Terra Boa and Santa Maria's half-moon-shaped shore on the south coast region. Fishing at the Palmeira Port, the natural pool at Buracona amid high cliffs, the kitesurfing spots of Kite and Ponta Preta beaches, and the dolphins and sharks in the Atlantic make the best combination of outdoor fun activities while on tour to the Sal Island.
Sal is a moderately flat island with an average elevation of four hundred and six meters at its highest point in Monte Grande. The general weather of the Island may vary significantly from that of the other islands that are around Sal, because the influence of the Atlantic Ocean and the winds affect them differently, from different levels and angles. The climate of Sal is typical of the desert climate, which is Köppen classified as BWh. The weather is characterized by mildly warm to hot temperature ranges throughout the year, with moderately minimal variations between the extremes. Also, Sal's climate is characterized by extremely minimal rainfall, with most days in the year going by without a single drop. The daily sunshine hours average six per day throughout the year, and couple up with the 73% average humidity to leave most days warm to hot, but moderately tolerable. Rainfall in Sal is very minimal. Most days, between March and July, experience dry days without any rainfall - the precipitation reading is 0mm (0"). However, August and September receive a few showers of the rain, gathering up to 14.3mm (0.6") and 33.8mm (1.3") of precipitation on average respectively. The rest of the months' record no more than 5.5mm (0.2") in rainfall on average. The temperature in Sal is moderately hot throughout the year. The average highs range between 24.1°C (75.4°F) and 30.2°C (86.4°F) on most days while the average lows range between 18.9°C (66°F) and 24.3°C (75.7°F) on most nights. Owing to its location in Cape Verde, on the Atlantic Ocean, Sal barely has extreme temperature ranges, and even in the hottest days, it feels much cooler with the prevailing breezes from the Ocean. For example, the lowest ever recorded temperature reading was 12°C (53.6°F), while the highest record temperature was 38°C (100.4°F). Sal is an all-year-round travel destination owing to the warm to hot and dry weather on most days across the entire year. From March to May, however, Sal’s turquoise blue waters are alive with the famous humpback whales migrating through. Between June and October, it is the turtle nesting season in Sal, yet another excellent tourist attraction activity. When the trade winds prevail between November and May, Sal attracts a large number of windsurfing and kitesurfing activities with visitors from far and wide.
