Weather in June
Temperature
The start of June signals a slight increase in the average high-temperature, moving from a moderately hot 75.4°F (24.1°C) in May to a still warm 81.3°F (27.4°C). Sierra Madre observes a noteworthy temperature drop from the daily highs during June nights, with a mean temperature of 57.7°F (14.3°C).Heat index
June's heat index is calculated to be 82.4°F (28°C). If exposure and activity persist, fatigue could ensue, possibly leading to heat cramps.It is essential to grasp that the heat index's numbers are for shade and light wind settings. The direct sunshine could escalate the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', reflects the feeling of heat when considering both air temperature and humidity. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. Exposure to direct sun rays can influence the heat you feel, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.

Take precautions against overexposure. Fair-skinned people may get burned in less than 20 minutes. It's important to stay in the shade and limit exposure to the sun from 10 a.m. to 4 p.m., when UV radiation is most intense, although remember that shade structures may not provide full sun protection. For a sun-safe wardrobe, go for clothes that are tightly woven and generously sized.
