Weather in July
Temperature
Mountain Lakes registers the highest average temperatures during the month of July, with peaks of 83.1°F (28.4°C) and lows of 64.8°F (18.2°C).Heat index
For most parts of July, the heat index is computed to be a tropical 89.6°F (32°C). Long-standing exposure coupled with ongoing activity could result in exhaustion, possibly causing heat cramps.Understand that the heat index values take into account shaded locations and mild winds. Exposure to the direct sun might augment heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. The impact of weather is personal, differing among a variety of people based on differences in body mass, height, and the level of physical exertion. Do note, being directly under sun rays can amplify the heat you feel, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Children often lack awareness of the importance of taking breaks and rehydrating. The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.
