Weather in July
Temperature
Henderson's warmest month, July, generally records average temperatures ranging from a high of 83.8°F (28.8°C) to a low of 70°F (21.1°C).Heat index
Throughout July, the heat index is appraised at a tropical 93.2°F (34°C). Preventive measures are required to mitigate the risk of heat cramps and heat exhaustion. Continuous activity may precipitate heatstroke.Understanding the heat index involves considering values for shaded locales with light wind. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', integrates the air's temperature and its humidity to showcase the felt temperature by people. The effect of weather is individual, with a variety of people experiencing it differently due to distinctions in body mass, height, and level of activity. Under direct sun rays, the felt temperature might be heightened, with the heat index increasing by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
