Weather in July
Temperature
July, recognised by an average high temperature of 87.6°F (30.9°C) and a low of 65.5°F (18.6°C), is Louisville's warmest month.Heat index
July's heat index is estimated at a very hot 100.4°F (38°C). Implement more safety precautions, heat cramps and heat exhaustion may happen. Persistent activity could induce heatstroke.The metrics for the heat index are tailored for both shady environments and light winds. The direct sunshine could escalate the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is found by incorporating humidity levels into the air temperature measurement. The perception of temperature can be subjective, varying based on activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Remember, direct sunlight exposure can heighten the heat impact and might increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. An elevated level of relative humidity hinders evaporation, leading to decreased heat elimination from the body, inducing a sensation of excess heat. Overheating dangers loom when the body's heat release mechanisms are overshadowed by excessive gain.

The month with the most rainfall is July, when the rain falls for 16.3 days and typically aggregates up to 2.2" (56mm) of precipitation.Snowfall

May through August, with an average maximum UV index of 6, are months with the highest UV index in Louisville. A UV Index estimate of 6 to 7 represents a high health hazard from unprotected exposure to Sun's UV rays for the average person.Note: The daily maximum UV index of 6 in July interprets into the following advice:
Stay clear of intense sun exposure. Solar protection is of utmost significance. Limit direct sun exposure especially between 10 a.m. and 4 p.m., when UV radiation is at its peak. However, keep in mind that shade structures may not provide full sun protection. Sunglasses that ward off UVA and UVB rays play a pivotal role in reducing solar eye damage.
