Weather in July

July is a month not to be missed for rain lovers, as the downpour reaches new heights with an astonishing 7.52" (191mm) of rainfall over 28.9 days. Despite the heavy rainfall, temperatures remain stable and ocean waters reach their warmest point. The rich tropical landscape of Santa Rita fully thrives in these conditions, proudly displaying its dense greenery. Though sunshine hours slightly drop, the beauty of this tropical oasis remains undiminished.

Temperature

Santa Rita's highest average temperatures are recorded in July and August, reaching a high of 84.7°F (29.3°C).

Heat index

The heat index value during July is calculated to be a torrid 95°F (35°C). More safety actions are required, heat exhaustion and heat cramps are probable. Long-term activity may precipitate heatstroke.
Understand that the heat index values take into account shaded locations and mild winds. Uninterrupted exposure to the sun may boost the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', combines both the air temperature and the humidity level to give a perceived human temperature. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Youths are typically more endangered than adults since they usually sweat less. Their larger skin surface concerning their smaller bodies and higher heat production due to activity further adds to their vulnerability.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. Under conditions of high temperature and humidity (enhanced heat index), sweat production is compromised, exacerbating the sensation of warmth. Overheating can ensue when the body accumulates more heat than it can release, and dehydration severity may vary.
