In winter, from December to February the temperatures are mild and the sky is often clear, so it's a spring-like weather. Lows are around 55/59 °F, and highs around 71/75 °F. However, there can be some cool days, especially in January, in which the temperature drops below 50 °F at night, and stay around 59/61 °F in the afternoon.
In spring the temperature rises fairly quickly, so much so that already in April highs are around 89 °F. Spring is also the season in which the warm wind blows more often from the Arabian desert, bringing dust and sand storms, and sudden increases in temperature, which can exceed 105 °F in April; sometimes this happens even in autumn, especially in October.
Summer from May to September is very hot, with highs from 100 to 107 °F, and lows around 77/84 °F. There are days in which the wind from the inland desert prevails, so that the daytime temperatures rise above 105 °F, and sometimes even 113/117 °F, while other periods are less hot but wetter, with highs around 99/100 °F, which can be even worse because they are sweltering. Over the course of the summer months, the relative humidity gradually increases, so that the second part of the season, in August and September, is particularly stifling. The combination of moisture and temperature that is observed in summer in the countries of the Persian Gulf, is actually one of the worst in the world.
Autumn, usually sunny, is still hot in October, when the maximum temperature is around 95 °F, while in November it drops to 82/84 °F.


The sea is a bit cool from January to March, particularly in February when it reaches the lowest temperature, about 68 °F, while it's still quite warm in December, when it's about 75 °F. In summer, the waters of the Persian Gulf become very warm, exceeding 85 °F from June to October.

When to go

The best time to visit Qatar runs from mid-November to mid-March: it is the only time of the year which is not hot. In general, the weather is mild and sunny from December to February, warm but not too much in November and March. Some cloudy days are also possible, sometimes with rain, especially from December to February.

What to pack

In winter: light clothes for the day, sweater and jacket for the evening and for cool days, scarf for the wind.
In summer: lightweight clothes, made of natural fabric (cotton or linen), desert turban, sweatshirt and scarf for air conditioned places. For women, it is better to avoid shorts and miniskirts outside of tourist resorts.
For the reef, snorkeling equipment, water shoes or rubber soled shoes.
