Metro Manila has registered anew its hottest day so far this year with an air temperature reading of 35.4 degrees Celsius around Wednesday afternoon.
The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) said the air temperature of 35.4 degrees Celsius was recorded at the Science Garden monitoring station in Quezon City at around 4 p.m. Wednesday.
However, it felt like 39.5 degrees Celsius due to high humidity in the air, the weather bureau said.
Heat index, or what humans perceive or feel as the temperature affects their body, is different from air temperature.
Heat index is a combination of air temperature and humidity, thus it is higher by at least 2 to 3 degrees Celsius from the actual air temperature.
Wednesday’s air temperature is the same as the 35.4 degrees Celsius recorded last April 6.
Likewise, PAGASA pointed out that the Science Garden monitoring station in Quezon City is the “most ideal” place to get the highest temperature in the metropolis because of the absence of “obstructions,” unlike at the NAIA and Port Area stations were “smoke, urban heat, buildings, and airplanes” affect the air temperature.
Based on the PAGASA data, the highest temperature in Philippine history is 42.2 degrees Celsius, recorded in Tuguegarao, Cagayan on May 11, 1969.
Meanwhile, the hottest day in Metro Manila was 38.5 degrees Celsius recorded on May 14, 1987.
PAGASA said warm and humid weather will prevail over most of the country this Thursday.
However, isolated rain showers or thunderstorms could be felt that may trigger flash floods or landslides over low-lying and mountainous areas.
