The climate in Yemen can be divided into three different areas: the deserts in the eastern and northern interior, the mountainous country and the coastal strip. In the deserts, the climate is dry and hot, with highs of up to 45 degrees in summer and 35 degrees in winter. The temperature difference between day and night is large. In the nights it can cool down to 10 degrees. Rain hardly falls. In the mountain regions of northern Yemen, the maximum temperatures are between 25 and 30 degrees. At altitudes above 2500 metres it cools down considerably in winter. In March and April, as well as from July to September, the rainy season is usually characterised by short, heavy downpours. Annual precipitation is between 400 and 750 litres per square metre, in the mountains it can be up to 1000 litres. The coastal region of Yemen has a subtropical climate with high temperatures and high humidity. In summer, temperatures can rise to over 40 degrees. At night it remains over 25 degrees, sometimes even over 30 degrees. In the winter months it is not as humid as in summer. The maximum temperatures then still reach between 28 and 30 degrees. Despite the high humidity, the annual precipitation totals of 25 to 150 litres are low.
Different periods are recommended depending on the holiday region. In the deserts and on the coast you should avoid the hot summer months. For trips to the high mountains, December is not recommended because of the low night temperatures. If you plan to visit several regions, April and May as well as September and October are the best months.
