Heat index is the measurement of how hot it really feels when relative humidity is factored in with the actual air temperature. The highest heat index so far this year was recorded in San Jose last April 20 at 58 degrees Celsius. The warm and humid weather across most parts of country can be attributed to the prevailing easterly winds originating from the Pacific, and the ridge of high pressure area extending across Northern Luzon.
