Weather in July

Marcus, Washington, in July sees a temperature change, with average high-temperatures moving from a pleasant 70.2°F (21.2°C) in June to a warm 80.6°F (27°C). Despite the high peak temperatures, Marcus witnesses an average nighttime cooling to a frosty 49.6°F (9.8°C) in July.Heat index
For most parts of July, the heat index is calculated to be 82.4°F (28°C). With ongoing exposure and activity, one might experience weariness, and heat cramps could ensue.Take into consideration that the heat index values are calculated for shade and light wind conditions. Direct sunlight has the potential to heighten heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', measures the perceived warmth when incorporating the humidity present in the air. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. Keep it in mind, direct sunlight can augment the heat you experience, possibly pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
