Weather in June
Temperature
With the onset of June, Rio experiences a subtle temperature shift, with the average high-temperature moving from a warm 75.4°F (24.1°C) in May to a still moderately hot 83.5°F (28.6°C). The nighttime temperature during June exhibits a clear drop from daytime highs, settling at an enjoyable 60.8°F (16°C).Heat index
For most parts of June, the heat index is computed to be a tropical 89.6°F (32°C). Persisting in activity during exposure could lead to weariness and subsequently to heat cramps.Remember that heat index calculations are made for conditions in the shade with light wind. Heat index values may rise by up to 15 Fahrenheit (8 Celsius) degrees when exposed to direct sunlight.
Note: The heat index, also known as 'real feel' or 'feels like', joins air temperature with relative humidity to produce a temperature perception for humans. Additional elements encompassing metabolic differences, the degree of physical activity, and attire can impact the individual's perception of temperature. Realize that direct exposure to sunlight can augment the felt heat, leading to a potential increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Children often lack awareness of the importance of taking breaks and rehydrating. The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.
