Weather in June

June presents a pronounced divergence from daily peak temperatures in San Bernardino, with the average low-temperature of 58.5°F (14.7°C).Heat index
During June, the heat index is computed to be a hot 86°F (30°C). Enduring exposure and unrelenting activity might cause a state of weariness, potentially leading to heat cramps.One should consider that heat index numbers are for shaded settings and light wind. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', combines air temperature and relative humidity to represent a human perceived temperature equivalent. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. 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 hold particular significance for children. Younglings frequently fail to recognize the requirement to rest and rehydrate. Thirst emerges late in dehydration - it is imperative to keep hydration levels high, particularly during extended physical exertions.
