Under the Köppen climate classification system, Singapore has a tropical rainforest climate with no distinctive seasons. Its climate is characterized by uniform temperature and pressure, high humidity, and abundant rainfall. Temperatures range from 22 °C to 34 °C (72° to 93 °F). On average, the relative humidity is around 90 percent in the morning and 60 percent in the afternoon. During prolonged heavy rain, relative humidity often reaches 100 percent.[30] The lowest and highest temperatures recorded in its maritime history are 18.4 °C (65.1 °F) and 37.8 °C (100.0 °F) respectively. The highest wind speed recorded was 150 km/h (93 mph) on 26 May 2007. June and July are the hottest months, while November and December make up the wetter monsoon season. From August to October, there is often haze, sometimes severe enough to prompt public health warnings, due to bushfires in neighbouring Indonesia.
