Weather in May
Temperature
May's onset is marked by a subtle temperature increase, moving from 77.4°F (25.2°C) in April to a still warm 85.3°F (29.6°C). Alto's temperature in May lowers to a consistent average of 63.9°F (17.7°C) during the nights.Heat index
The heat index value during May is calculated to be a sweltering 95°F (35°C). Incorporate additional safety actions, heat cramps and heat exhaustion are possible. Long-term activity may induce heatstroke.Research indicates the heat index considers values in shaded locales and with light winds. The direct sunshine could escalate the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is an aggregate value of air's warmth and moisture to show the human-felt temperature. Metabolic differences, pregnancy status, and the level of physical activity are additional factors influencing an individual's weather perception. Direct sunlight can potentially raise the heat index by 15 Fahrenheit (8 Celsius) degrees, so it's crucial to consider. Heat index values hold great significance to children. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
To combat high temperatures, the human body perspires and relies on sweat evaporation for cooling. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. As body temperatures escalate without effective heat release, one might face dehydration threats.
