Note: The heat index, also known as ‘real feel’, ‘felt air temperature’, ‘feels like’, or ‘apparent temperature’, is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent.
This effect is subjective, depending on the activity and individual’s heat perception influenced by various reasons (metabolic differences, differences in body mass, height, and shape, pregnancy). Be aware that direct exposure to sunlight increases heat impact and may raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Children are often less aware of the need to rest and re-hydrate. Thirst is a late sign of dehydration – it is vital to remain hydrated, particularly during prolonged physical activities.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. A higher relative humidity affects normal body cooling by reducing the evaporation rate, subsequently lowering the rate at which the body cools and increasing the perception of heat. When heat gain surpasses the level the body can shed, body temperature begins to increase, and consequently, overheating and dehydration can occur, with varying severity.

Sun-protective clothing, a long-sleeved shirt and pants, a wide-brimmed hat, and UVA and UVB-blocking sunglasses are particularly helpful in blocking UV radiation’s harmful effects. Beware! The reflection of water and sand dramatically increases exposure to the UV rays.

Where does this data come from
Weather data for Puerto Rico was collected from the MERRA-2 project from NASA, which used a climate model combined with historical data from weather stations around the world to estimate what the conditions were like for every point on the Earth.
For all data based on historical data, we’ve averaged the data from the past 11 years (2010-2020).
For example, for the hourly temperature at 10am, we’ve looked at the temperature at 10am on every day in October (e.g., October 1, October 2, etc. in 2010, 2011, etc.) and took the arithmetic mean. We did not smooth the data, so for example, our daily temperature line will have some randomness due to the fact that weather is random in the first place.
