July weather forecast
Metairie, LA

July continues the summer rhythm initiated by June. Metairie, during mid-summer, displays hot and muggy weather, with distinctive high humidity. A downtrend in the wind speed is observed, setting a more tranquil atmosphere. However, even amid this calm, it is worth noting the frequency of rainfall days spikes to its highest at 13.3 days. Consequently, Metairie witnesses its peak annual rainfall of 1.3in, the highest in the year.

Temperature

Metairie's warmest month, July, generally records average temperatures ranging from a high of 89.2°F (31.8°C) to a low of 78.4°F (25.8°C).

Heat index

July's mean heat index is calculated to be a blisteringly hot 107.6°F (42°C). Additional precautions are required to avert heat cramps and heat exhaustion. Persistent activity may culminate in heatstroke.
When considering the heat index, it's pivotal to note it is for shade and mild wind conditions. Heat index values might soar by up to 15 Fahrenheit (8 Celsius) degrees with exposure to direct sunshine.
Note: The heat index, also known as 'real feel' or 'felt air temperature', binds temperature metrics with humidity values to give a sense of the actual warmth. An individual's perception of weather can be affected by a variety of elements including metabolic differences, being pregnant, and their level of physical exertion. Direct sunlight can potentially raise the heat index by 15 Fahrenheit (8 Celsius) degrees, so it's crucial to consider. Heat index values are particularly important for children. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
Normally, the human body cools itself through perspiration, which removes excessive heat by evaporating sweat. An elevated level of relative humidity hinders evaporation, leading to decreased heat elimination from the body, inducing a sensation of excess heat. When heat surpasses the body's release mechanisms, dehydration and overheating risks become pronounced.

UV index

May through September, with an average maximum UV index of 7, are months with the highest UV index. A UV Index estimate of 6 to 7 represents a high health vulnerability from exposure to the Sun's UV rays for the ordinary person.
Note: A daily maximum UV index of 7 in July translates into the following instructions:
Endorse precautions and be consistent with sun safety guidelines. Preventing sunburn is paramount. Stay in the shade and avoid direct Sun exposure from 10 a.m. to 4 p.m., a period when UV radiation is particularly strong, noting that parasols or canopies may not offer total sun protection. To mitigate harm from sun exposure, pick sunglasses offering UVA and UVB defense.
