Weather in June
Temperature
June's onset brings a rise in the average high-temperature, moving from a moderately hot 75.7°F (24.3°C) in May to a hot 86.4°F (30.2°C). Saint Thomas's temperature lowers to a mean of 65.5°F (18.6°C) during the nights in June.Heat index
In June, the average heat index is evaluated at a very hot 98.6°F (37°C). Implement enhanced safety actions, heat cramps and heat exhaustion could occur. Sustained activity might result in heatstroke.Observations indicate that the heat index values are for shady locations with light wind. Under direct sunshine, the heat index values might be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', takes into account both air temperature and humidity to illustrate what people actually feel. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. One's exposure to direct sunlight has the potential to intensify the heat sensation, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Young ones often ignore the need to take a break and drink fluids. Thirst is a late-stage symptom of dehydration - hence, maintaining hydration, particularly during extended physical activities, is crucial.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. When the level of relative humidity is elevated, evaporation diminishes, causing more warmth to be retained in the body than in dry air. Overheating and potential dehydration arise when body heat gain eclipses its release capability.

Use measures and accept sun safety conventions. Guarding against skin and eye trauma is of high priority. Stay in the shade and avoid direct Sun exposure from 10 a.m. to 4 p.m., a time when UV radiation is at its strongest, and remember that parasols or canopies do not offer full protection. Sun-protective clothing, a long-sleeved shirt and pants, a wide-brimmed hat, and UVA and UVB-blocking sunglasses are particularly helpful in blocking UV radiation's harmful effects.
