In terms of climatology, July marks the peak of the summer season in Punta Santiago.

However, the level of sunshine received remains high. With a temperature peak at 84.2°F (29°C), it also records the highest rainfall for the year at 4.57" (116mm) scattered over 23.7 days.

Temperature

Punta Santiago registers an average high-temperature of a still warm 84.2°F (29°C) at the commencement of July, closely related to the preceding month. Punta Santiago, during July nights, witnesses an average temperature marginally cooler than its daytime highs, at a still warm 78.4°F (25.8°C).

Heat index

July's heat index is estimated at a torrid 95°F (35°C). Incorporate special precautions, risk of heat exhaustion and heat cramps is substantial. Sustained activity could cause heatstroke.
In terms of the heat index, values are set with light wind and shade conditions in mind. The heat index may scale up by 15 Fahrenheit (8 Celsius) degrees with direct sun exposure.
Note: The heat index, also known as 'feels like' or 'real feel', takes into account both air temperature and humidity to illustrate what people actually feel. One's perception of temperature is subjective, varying based on their activity and individual heat perception, influenced by factors like wind, clothing, and metabolic variations. Remember, direct sunlight exposure can heighten the heat impact and might increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Youngsters typically face more danger than adults since they sweat less. Their larger skin surface compared to their small bodies and heightened heat production from their activities augment their vulnerability.
The process of perspiration is vital for the human body to get rid of excess warmth by allowing sweat to evaporate. An increase in relative humidity disrupts body cooling by slowing the evaporation rate, thereby reducing the rate at which the body cools and amplifying the sense of heat. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.

Reflections from sand and water can intensify the Sun's UV radiation.
