Weather in July
Temperature
Sierra Madre experiences a transition to a hot 86.5°F (30.3°C) in average high-temperatures with the arrival of July, not greatly differing from June's 81.3°F (27.4°C). Throughout July, Sierra Madre braces for a considerable drop from daytime highs, with an average low-temperature of 63.5°F (17.5°C).Heat index
The heat index value during July is calculated to be a tropical 89.6°F (32°C). If one persists in activity during exposure, it could induce weariness and subsequently, heat cramps.It is worth noting that heat index values are gauged for conditions in the shade and light breezes. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. Direct exposure to the sun's rays can enhance the felt temperature, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.

Ward off overexposure. Defence against solar harm is crucial. Stay in the shade and limit sun exposure from 10 a.m. to 4 p.m., when UV radiation is most potent. Keep in mind that shade structures like parasols or canopies do not offer full protection. It's wise to wear UVA and UVB-blocking sunglasses when the sun shines brightly.
