Weather in July
Temperature
July, marked by an average high-temperature of 83.1°F (28.4°C) and a low-temperature of 63.7°F (17.6°C), is the warmest month.Heat index
For most parts of July, the heat index is computed to be a hot 89.6°F (32°C). Persisting in activity during long-term exposure might induce weariness, with subsequent heat cramps.Be aware that heat index ratings are designed for shaded locations and minor breezes. Heat index values have the potential to be boosted by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'feels like', gives an indication of how one might feel in terms of heat after considering humidity. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. When you're directly under the sun's rays, remember that the heat index may surge by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
