July weather forecast
Chahal, Guatemala

July, like June, is another hot summer month in Chahal, Guatemala, with an average temperature fluctuating between 21°C (69.8°F) and 31°C (87.8°F).

July's beginning signals an average high-temperature of a still tropical 31°C (87.8°F), barely different from June's 31.1°C (88°F). An average low-temperature of 21°C (69.8°F) is recorded in the month of July.

Heat index

The heat index value for July is appraised at a blisteringly hot 42°C (107.6°F). Take special precautions - heat exhaustion and heat cramps are expected. Heatstroke may occur with lengthy activity.
The heat index's values are generally associated with conditions in shade and light breezes. In the presence of direct sunshine, the heat index could be augmented by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', blends air temperature and moisture content to represent the felt temperature to humans. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. It is noteworthy that being in direct sunlight can enhance the weather's impact, raising the heat index by as much as 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.
The body's natural response to excessive warmth is perspiration, as it allows for cooling through sweat evaporation. Under high air temperature coupled with high humidity (high heat index), the body's perspiration is reduced, intensifying the sensation of heat. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.
