Weather in July

July, like June, is another tropical summer month in Santo Domingo, Cuba, with an average temperature fluctuating between 32.3°C (90.1°F) and 23.5°C (74.3°F).

Temperature

In July, the average high-temperature registers at a still hot 32.3°C (90.1°F), nearly identical to June's 31.6°C (88.9°F). The nights of July in Santo Domingo anticipate an average low-temperature of 23.5°C (74.3°F).

Heat index

For most parts of July, the heat index is calculated to be a life-threatening hot 45°C (113°F). Careful: Heat exhaustion and heat cramps are anticipated. With ongoing exertion, heatstroke becomes a possibility.
Take into consideration that the heat index values are calculated for shade and light wind conditions. The heat index can potentially augment by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'real feel' or 'apparent temperature', joins air temperature with relative humidity to produce a temperature perception for humans. Factors encompassing physical activity, clothing, and metabolic differences have a role in shaping the individual's impression of temperature. 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 particularly relevant to children. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
Evaporation of sweat is the main factor behind the cooling effect of perspiration in the human body. When the air contains significant moisture, the efficiency of the evaporation process decreases, preventing the body from cooling down effectively and creating a feeling of overheating. The body is at risk of dehydration and related complications when it fails to shed excessive heat.

Humidity

In Santo Domingo, the average relative humidity in July is 79%.

Rainfall

In July, the rain falls for 21.6 days. Throughout July, 69mm (2.72") of precipitation is accumulated. Throughout the year, there are 187.4 rainfall days, and 558mm (21.97") of precipitation is accumulated.

Sunshine

July has the most sunshine of the year, with an average of 11.1h of sunshine.

UV index

The months with the highest UV index are April through September, with an average maximum UV index of 7. A UV Index reading of 6 to 7 represents a high health risk from exposure to the Sun's UV radiation for ordinary individuals.
Note: The maximum daily UV index of 7 in July converts into the following recommendations:
Elude overexposure. Fair-skinned people could get burnt in less than 20 minutes. Minimize exposure to direct sunlight and seek shade from 10 a.m. to 4 p.m., when UV radiation is most intense, but remember that shade structures may not offer complete protection. Employ a wide-brim hat for potent defense against up to 50% of UV rays.
