Kuwait has one of the most extreme climates of any country that welcomes visitors. The short answer: come between November and March. The rest of the year is punishingly hot.
Winter (December-February) is the best time to visit. Daytime temperatures hover around 18-22C, nights can drop to single digits, and the occasional rain shower turns the desert green. This is when Kuwaitis themselves spend time outdoors, and when the city feels most alive.
Spring (March-April) is still pleasant in March, but by April temperatures are already climbing past 35C and sandstorms become common. The desert wind can blow hot sand through the city for days at a time.
Summer (May-September) is ferocious. Temperatures regularly exceed 45C and can reach 50C or higher. Humidity spikes along the coast. The streets empty during the day and life retreats into air-conditioned interiors. Many wealthier Kuwaitis leave the country entirely. If you must visit in summer, plan all outdoor activity for early morning or after sunset.
Autumn (October-November) sees temperatures gradually dropping back below 30C by November, making it a reasonable shoulder season.
Ramadan shifts dates each year (it follows the Islamic lunar calendar) and has a significant impact on daily life. Restaurants are closed during daylight hours, working hours are shortened, and the pace of the city changes. The evenings come alive after the iftar meal at sunset, and there is a festive atmosphere, but daytime can feel deserted.
Key holidays include National Day (February 25) and Liberation Day (February 26), which together create a week of celebrations with fireworks, parades, and patriotic fervour. The Hala February Festival, spanning much of the month, features carnivals, concerts, and shopping events across the city.
