Weather in June
Temperature
Julian's June weather indicates a minor increase in high-temperatures, edging from May's moderately hot 73.6°F (23.1°C) to a still warm 81.3°F (27.4°C). June nights present a sharp contrast to daytime highs, with average temperatures of 56.3°F (13.5°C).Heat index
June's average heat index is calculated to be 82.4°F (28°C). If one sustains activity during exposure, it could lead to a sense of fatigue, with a chance of heat cramps.Bear in mind that the heat index values are determined for shaded areas and light breezes. The heat index could see an increase by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'apparent temperature' or 'real feel', marries air temperature and humidity to produce a value illustrating perceived warmth. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. Direct sun rays can make one feel hotter, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Children often fail to understand the importance of rest and rehydration. Thirst is a late manifestation of dehydration - hence, it is crucial to stay hydrated, especially during ongoing physical activities.
