Climate data for Singapore (1991–2020 normals, extremes 1929–1941 and 1948–present) Month Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec
A weather station was set up in Outram that year to measure monthly rainfall, marking the beginning of the "climate station" used to compile climatological data for Singapore. [4] The responsibility for collecting weather data was assigned to a new Meteorological Branch under the Malayan Survey Department in 1927. [5]
Specific humidity (or moisture content) is the ratio of the mass of water vapor to the total mass of the air parcel. [15] Specific humidity is approximately equal to the mixing ratio, which is defined as the ratio of the mass of water vapor in an air parcel to the mass of dry air for the same parcel.
Fastest ever recorded: 484±32 km/h (301±20 mph) (3-second gust); calculated by a DOW (Doppler On Wheels) radar unit in the 1999 Bridge Creek–Moore tornado between Oklahoma City and Moore, Oklahoma, USA, 3 May 1999. Recently, the wind speeds were re-examined and adjusted to a maximum official wind speed of 321 mph (516.6 km/h).

A given value of relative humidity causes larger increases in the heat index at higher temperatures. For example, at approximately 27 °C (81 °F), the heat index will agree with the actual temperature if the relative humidity is 45%, but at 43 °C (109 °F), any relative-humidity reading above 18% will make the heat index higher than 43 °C.

A humid subtropical climate is a subtropical-temperate climate type, characterized by long and hot summers, and cool to mild winters. These climates normally lie on the southeast side of all continents (except Antarctica), generally between latitudes 25° and 40° and are located poleward from adjacent tropical climates, and equatorward from either humid continental (in North America and Asia ...
