Weather in June
Temperature
In June, Heathrow's weather conditions record an average high-temperature of a tropical 89.2°F (31.8°C), demonstrating little divergence from the preceding month. During June, the average low-temperature is recorded at a warm 74.3°F (23.5°C).Heat index
For June, the heat index is computed to be a blistering 107.6°F (42°C). Adopt heightened safety measures, heat cramps and heat exhaustion may occur. Sustained activity might cause heatstroke.Keep in mind the heat index values are meant for areas in shade and with light wind. In the presence of direct sunshine, the heat index could be augmented by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. Factors encompassing physical activity, clothing, and metabolic differences have a role in shaping the individual's impression of temperature. Be mindful that being in direct sunlight might mean feeling hotter, with the heat index rising by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. 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.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. When the air contains significant moisture, the efficiency of the evaporation process decreases, preventing the body from cooling down effectively and creating a feeling of overheating. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.
