Situated only one degree north of the equator, it is not surprising that Singapore has a tropical climate, meaning that it is hot and humid all year round with hardly any variation in temperature between seasons; in fact, Singapore doesn't really have seasons. Travellers to Singapore would be wise to take an umbrella, because rain is abundant and possible all year round, usually falling in heavy downpours. The wettest months are between November and January, which is the monsoon period. There is generally more rain in the west of the island than in the east. Average temperatures range between 79°F (26°C) and 86°F (30°C) during the day, with cooler temperatures at night. April and May are the hottest months. Temperatures in Singapore can reach as high as 95°F (35°C) and the lowest recorded temperature in the country was 67°F (19°C) in 1934. The air-conditioning in most buildings provides a welcome escape from the heat and humidity, but is sometimes so cool that visitors will require light sweaters indoors. Between June and September Singapore may suffer from air pollution due to forest fires in Indonesia.There is no concrete best time to visit Singapore weather-wise, and it is best to time holidays to coincide with festivals and events that are of interest.
