June weather forecast
Cabo Rojo, PR

Cabo Rojo greets the onset of summer with aplomb. Slight fluctuations in the weather are present when compared with the preceding month. However, the uniqueness of the weather in the city, the higher temperatures and increased daylight hours, adds to the charm that the city offers.

Temperature

The shift from May to June is characterized by an average high-temperature of a still moderately hot 85.5°F (29.7°C), not significantly different from the 83.8°F (28.8°C) of May. June nights witness a mild cool down to an average low of 78.4°F (25.8°C).

Heat index

The heat index value during June is calculated to be a sweltering 96.8°F (36°C). More safety actions are required, heat exhaustion and heat cramps are probable. Long-term activity may precipitate heatstroke.
Thinking about the heat index, one should account for its values in shaded areas with gentle breezes. Being exposed to direct sunshine might trigger a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', joins air temperature with relative humidity to produce a temperature perception for humans. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. Do note, being directly under sun rays can amplify the heat you feel, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Children often overlook the necessity for resting and fluid replenishment. Thirst is a late sign of dehydration - thus, it is critical to stay hydrated, especially during extended periods of physical activities.
The innate cooling system of the human body revolves around perspiration, with the evaporation of sweat being central to this process. Higher relative humidity impedes evaporation, thus reducing heat dispersion from the body, culminating in a sensation of overheating. When heat surpasses the body's release mechanisms, dehydration and overheating risks become pronounced.

UV index

Note: In June, the average maximum UV index of 7 translates into the following recommendations:
Guard against overexposure. Protection from sun-induced harm is essential. The hours from 10 a.m. to 4 p.m. have the most intense UV radiation. As much as possible, limit direct sun exposure during this period. Sunglasses providing both UVA and UVB protection are non-negotiable on sunlit days.
