Weather in February
Temperature
February, noted for its average high-temperature of 29.1°C (84.4°F) and an average low-temperature of 22.6°C (72.7°F), is considered the coldest month.Heat index
February's average heat index is evaluated at a very hot 36°C (96.8°F). Extra precautions are necessary, heat cramps and heat exhaustion are plausible outcomes. Extended activity could lead to heatstroke.Heat index evaluations are typically in the context of light winds and shaded environments. Direct sunshine exposure could raise heat index values by as much as 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', ties air temperature with relative humidity to produce the perceived temperature sensation. The effect of weather is individual, with a variety of people experiencing it differently due to distinctions in body mass, height, and level of activity. When exposed to direct sunlight, it's possible for the heat index to increase by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Youths are typically more endangered than adults since they usually sweat less. Their larger skin surface concerning their smaller bodies and higher heat production due to activity further adds to their vulnerability.
Sweat evaporation, driven by perspiration, is the method the human body uses to rid itself of excessive warmth. Higher relative humidity impedes evaporation, thus reducing heat dispersion from the body, culminating in a sensation of overheating. When heat gain exceeds the level the body can remove, body temperature begins to rise, and heat-related illnesses and disorders may develop.

In John, in February, during 23.7 rainfall days, 51mm (2.01") of precipitation is typically accumulated. Throughout the year, there are 253 rainfall days, and 878mm (34.57") of precipitation is accumulated.Daylight

The months with the lowest UV index in John are January through June and December, with an average maximum UV index of 6. A UV Index reading of 6 to 7 represents a high threat to health from unsafe exposure to UV radiation for average individuals.Note: In February, the maximum UV index of 6 suggests these recommendations:
Elude overexposure. Fair-skinned people could get burnt in less than 20 minutes. Limit your direct sun exposure, especially between 10 a.m. and 4 p.m., when UV radiation is strongest. Shade structures might not provide complete sun protection. Experience reduced UV exposure by about half when donning a wide-brim hat.
