Temperature

The shift into July finds Guanabana, Cuba, at an average high-temperature of a still tropical 32°C (89.6°F), closely comparable to June's conditions. July nights cool down to an average low-temperature of 24.3°C (75.7°F).

Heat index

For most parts of July, the heat index is evaluated at a scorching 44°C (111.2°F). Forewarned: Heat cramps and heat exhaustion are anticipated. Ongoing physical activity increases the likelihood of heatstroke.
Observations indicate that the heat index values are for shady locations with light wind. With exposure to direct sunshine, the heat index could climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. Exposure to direct sun rays can influence the heat you feel, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. An increase in relative humidity retards evaporation, subsequently reducing the body's heat removal rate and leading to a sensation of being overly warm. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.

Note: The maximum daily UV index of 7 in July interprets into the following recommendations:
Stay clear of intense sun exposure. Solar protection is of utmost significance. Avoid direct exposure to the Sun between 10 a.m. and 4 p.m., the peak period for UV radiation, noting that objects like parasols or canopies might not offer complete sun protection. For effective sun eye protection, rely on sunglasses certified for UVA and UVB resistance.
