Editing Geography of Yemen (section)

==Climate==
Temperatures are lower in most of Yemen than in most of the [[Arab world]] due to most of the country being at high elevation. Rainfall is higher at higher elevations. The highlands enjoy a temperate, rainy summer with an average high temperature of {{convert|21|°C|°F|1|abbr=on}} and a cool, moderately dry winter with temperatures occasionally dipping below {{convert|0|°C|°F|1|abbr=on}}. The climate of the [[Tihamah]] (western coastal plain) is tropical; temperatures occasionally exceed {{convert|54|°C|°F|1}}, and the humidity ranges from 50 to 70 percent. Rainfall, which comes in irregular heavy torrents, averages {{convert|130|mm|in|2}} annually. In Aden the average temperature is {{convert|25|°C|°F|1}} in January and {{convert|32|°C|°F|1}} in June, but with highs often exceeding {{convert|37|°C|°F|1}}. Average annual rainfall is {{convert|127|mm|in|0}}. The highest mountainous areas of southern Yemen receive from {{convert|520|to|760|mm|in|1|abbr=on}} of rain a year. Some areas of the western highlands, most notably Ibb and Ta'izz, receive from about {{convert|1000|–|1500|mm|in|1}} of rain each year. The capital, Sana'a, receives around {{convert|300|mm|in|1|abbr=on}} a year, it is not uncommon for the northern and eastern sections of the country to receive no rain for five years or more. The Wadi Hadhramaut in the eastern part of Yemen is arid and hot, and the humidity ranges from 35 percent in June to 64 percent in January. Yemen has the most fertile land in the Arabian peninsula.
