Siem Reap is Cambodia's second-largest city and the capital of Siem Reap Province in the northwest. It is best known as the gateway to the temples of Angkor and the Tonlé Sap lake. The city lies in the lowlands north of the Tonlé Sap and has a tropical savanna climate with a distinct wet and dry season. Like much of inland Cambodia, Siem Reap experiences high temperatures throughout the year. The wet season runs from roughly May to October, when the southwest monsoon brings regular afternoon showers and high humidity. The dry season from November to April is sunnier and less humid, with December to February often the most pleasant. March to May is typically the hottest period before the rains return. Rainfall is moderate compared with the coastal southwest; the area is not in the wettest monsoon belt. Temperatures can exceed 35 °C in the hot season and drop to the low 20s °C at night in the cool season.
