Heat index

For most parts of July, the heat index is computed to be a torrid 98.6°F (37°C). More protective measures are required - heat exhaustion and heat cramps are likely. Heatstroke may follow lengthy activity.
It is crucial to understand that heat index figures are for shade and gentle wind conditions. Heat index values have the potential to be boosted by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is a value derived by merging air temperature with the humidity to convey how the climate feels. 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. By being directly under the sun, it's possible for the felt temperature to increase by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. 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.
The body's natural response to excessive warmth is perspiration, as it allows for cooling through sweat evaporation. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. Temperature imbalances caused by excessive heat retention can trigger heat-related maladies.
