The climate of the small archipelago of Bahrain is desert, mild in winter and very hot in summer.
Basically there are two main seasons: a cooler season from December to mid-March, and a hot season from April to October, in which we can distinguish a very hot period from June to September.
Due to the influence of sea, the temperature range between night and day is low, and the humidity is high, except when the winds blow from the interior of Arabia.
In winter, from December to mid-March, the temperatures are pleasant, especially in December and March, when lows are around 16/18 °C and highs are around 22/25 °C. The sun often shines, and the rains are scarce and rare. At times there can be even warm days, with peaks at around 30 °C, when the winds blow from the south, but in these months this winds are rare.
In mid-winter, in January and February, the temperatures are a bit lower, so that highs are around 20/21 °C; sometimes a cold air mass from the north can lower the daytime temperature to around 15 °C, and that of the night to around 10 °C.
Summer in Bahrain is very hot and sunny, with highs around 36/38 °C from June to September, but they can easily reach 40 °C; lows are around 29/31 °C from June to September, and the humidity from the Persian Gulf makes the heat unbearable. However, hotels, offices and restaurants are equipped with air conditioned.
Here are the average temperatures of the capital Manama.

The prevailing wind in Bahrain is the Shamal, which is moist and blows from the north-west, more frequently in the summer months. Another wind, hot and dry, the Qaws, can blow throughout the year, but preferably in spring; it blows from the south and it's able to raise the temperature to about 30 °C in winter and about 40 °C and above from April to October, while drastically lowering the humidity, in addition to causing dust storms and sand.
As mentioned, the climate in Bahrain is desert, in fact just 70 millimetres of rain per year fall; most of the rains occur in the winter months, however, they are are irregular, and occasionally in winter there can be some intense rainfalls, which, being concentrated in a few hours, can cause flash floods.
Here is the average precipitation.

Unlike other Gulf emirates, in Bahrain there are ancient springs of fresh water, but nowadays even here more than half of the fresh water consumed is obtained by seawater desalination.


The sea temperature is definitely warm in summer, since it exceeds 30 °C for a few months (in fact in this season it is the warmest sea in the world), while it is cool only from January to March, when it drops to 20/21 °C.

When to go

The best time to visit Bahrain goes from mid-November to mid-March, mainly to avoid the summer heat. Between December and February, the weather is generally mild and pleasant, but you must put into account some cool days, especially in January and February, a bit of cold sometimes at night, and even some rain. In November, the weather is still warm but not excessively hot, in fact highs are around 28 °C, and in March they are around 25 °C.
