Weather in October
Temperature
October brings an average high-temperature of a tropical 30°C (86°F), showing a slight difference from September's 29.1°C (84.4°F). The October nights show a slight decrease to a mean low-temperature of 25°C (77°F).Heat index
In October, the heat index is calculated to be a fiery hot 38°C (100.4°F). Take extra safety measures to prevent heat exhaustion and heat cramps. Heatstroke could follow lengthy activity.Keep in mind the heat index values are meant for areas in shade and with light wind. When under direct sunshine, the heat index may be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', binds temperature metrics with humidity values to give a sense of the actual warmth. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. Under direct sun rays, the felt temperature might be heightened, with the heat index increasing by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
Sweat evaporation, driven by perspiration, is the method the human body uses to rid itself of excessive warmth. Heightened relative humidity interferes with the body's usual cooling mechanism by reducing evaporation, subsequently decreasing the body's cooling rate and increasing the sensation of heat. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.
