The Saudi Arabia Climate can be described as a desert climate, with extensive fluctuations in day and night temperature. A point to keep in mind about the Geography of Saudi Arabia is that whilst the country principally has a desert climate, the coastal areas show a manifest change of climate from that found in the rest of the country. The Climate of Saudi Arabia is distinct by high temperatures in summer that frequently shoot up to 45 degrees celsius or more, so make sure to hoard up on sun protection stuff, if you're planning a trip there in summer. The best period for Saudi Arabia sightseeing is spring and autumn when the average temperature remains approximately 29 degrees Celsius.
In winter, the temperatures rarely go below freezing point, so if you're willing to take on the exhilaration of the strong winds that occur all through the period, you could visit the country in winter too. The coastal lands, near the Red Sea and the Persian Gulf, can be visited most times of the year, because of their pleasant climate, if you take care to shun spring and summer, when the regions experience influential sand storms and dust storms. Saudi Arabia experiences its precipitation in blinking squirts, throughout the year. The district of Asir experiences monsoons, with moderately heavy downpour, between October and March.
