Iraq has a hot, dry climate characterized by long, hot, dry summers and short, cool winters. The climate is influenced by Iraq's location between the subtropical aridity of the Arabian desert areas and the subtropical humidity of the Persian Gulf. January is the coldest month, with temperatures from 5°C to 10°C, and August is the hottest month with temperatures rising up to 30°C and more.
In most of the areas, summers are warm to hot with mostly sunshine, but high humidity on the southern coastal areas of the Persian Gulf. Daily Temperatures can be very hot; on some days temperatures can reach easily 45°C or more, especially in the Iraqi desert areas which causes a danger of heat exhaustion. Hot, dry desert winds can be very strong sometimes, and can cause violent sandstorms.
About 70 percent of the average rainfall in the country falls between November and March; June through August are often rainless. Rainfall varies from season to season and from year to year. Precipitation is sometimes concentrated in local, but violent storms, causing erosion and local flooding, especially in the winter months.
