For half the year, the climate across the plains of Qatar is pretty unforgiving. During summer (May to September), temperatures generally average 35°C (95°F), but it's not uncommon for the mercury to rise to 50°C (122°F). The 90% humidity that comes with this time of year sags over the peninsular like a bad hangover and frequent sandstorms are an added irritation. During winter months (December-February) there's the odd shower but the days are mild and pleasant and evenings are cool. Throughout the year, but especially in spring, Qatar is subject to sandstorms; rainstorms can also hit the country in December and January, causing road closures.
