Geographical setting and islands

Following the return of Janan to

in March 2001, that state of Bahrain consists of 33 natural islands in the archipelago. Around most of Bahrain is a relatively shallow inlet of the Persian Gulf known as the

. Bahrain has two seasons: an extremely hot summer and a relatively mild winter. During the summer months, from April to October, afternoon temperatures average and can reach during May, June and July. The combination of intense heat and high humidity makes this season uncomfortable. In addition, a hot, dry southwest wind, known locally as the qaws, periodically blows sand clouds across the barren southern end of Bahrain toward Manama in the summer. Temperatures moderate in the winter months, from November to March, when the range is between . However, humidity often rises above 90% in the winter. From December to March, prevailing winds from the northwest, known as the shamal, bring damp air over the islands. Regardless of the season, daily temperatures are fairly uniform throughout the archipelago. Note that the coldest temperature ever recorded in Bahrain was on January 20, 1964, when it dropped to -5 °C (23 °F) in Awali and 2.7 °C (36 °F) at Bahrain International Airport. That particular freeze was accompanied by a white-out, with icicles forming on trees and fences at Awali. Bahrain receives little precipitation. The average annual rainfall is , usually confined to the winter months. No permanent rivers or streams exist on any of the islands. The winter rains tend to fall in brief, torrential downpours, flooding the shallow
