Winter, from December to February, is mild: the daily average temperature in January is 13.5 degrees Celsius (56 °F). Nights are cool, on average about 8/10 °C (46/50 °F), but sometimes the temperature can drop to 0 °C (32 °F). Days are mild or pleasantly warm, around 19 °C (66 °F) in January, and 21/22 °C (69/71 °F) in December and February, but with peaks of 27/30 °C (81/86 °F) when the wind blows from the south. In winter the sun often shines, but some cloudy days also possible, even with some rain.
In spring, the prevailing weather is nice and sunny; the temperature rises rapidly, and already in April highs are around 33 °C (92 °F). The wind from the Arabian desert can raise the temperature and bring sandstorms: as early as in April it can exceed 40 °C (104 °F), and in May even 45 °C (113 °F).
Summer in Kuwait is scorchingly hot and windy; the prevailing wind blows from the interior, therefore the influence of the sea is minimal. From June to August, the temperature is normally around 45/46 °C (112/115 °F), and around 29/30 °C (84/87 °F) at night. High-temperature records are around 52/53 °C (125/127 °F). Relative humidity is very low (it often falls below 10%), and combined with the wind, it can cause dehydration. Fortunately, public buildings and hotels are equipped with air conditioning.
The small island of Failaka is usually torrid as well, because it receives the wind from the continent, but sometimes it can be muggy, especially in September and October, in the days when the wind calms down a bit.
In autumn, the weather is still hot and sunny in October, while during the month of November the temperature drops below 30 °C (86 °F).



In Kuwait the sun shines all year round, sometimes however some cloud banks can pass even in summer.

When to go

---

The best time to visit Kuwait runs from mid-November to mid-March. In winter, from December to February, it can sometimes get cold at night, and there can be some rain, but at least you avoid the torrid heat. In early November and late March, sometimes it can be hot. However, in Kuwait, the heat is almost always torrid, therefore not humid, so it is more bearable than in other countries of the Persian Gulf; it's important to drink a lot and to be protected from the sun.
