For July, the heat index is estimated at a hot 87.8°F (31°C). Prolonged exposure combined with continuous activity could lead to exhaustion, and possibly heat cramps.Take into consideration that the heat index values are calculated for shade and light wind conditions. Direct sunlight might lead to a heat index increase by up to 15 Fahrenheit (8 Celsius) degrees.
