June weather forecast
Guatemala, Cuba

June, the first month of the summer in Guatemala, is a tropical month, with temperature in the range of an average high of 30.9°C (87.6°F) and an average low of 22.8°C (73°F).

Temperature

With June's arrival, Guatemala notes an average high-temperature of a hot 30.9°C (87.6°F), closely following the trend of the preceding month. An average temperature of 22.8°C (73°F) is recorded in Guatemala during the nights in June.

Heat index

For June, the heat index is calculated to be a scorching 41°C (105.8°F). Implement more preventive measures, heat cramps and heat exhaustion are probable. Heatstroke might result from extended activity.
Evaluating the heat index requires understanding its values in the shade and with gentle winds. Direct sunshine exposure could raise heat index values by as much as 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is a measure that combines air temperature and relative humidity into a single value that indicates how hot the weather feels. The influence of weather is personal, differing among a variety of individuals based on differences in body mass, stature, and the level of physical activity. It is essential to realize that direct sunlight can escalate the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
The natural cooling mechanism in humans involves perspiration, where the evaporation of sweat balances out excessive warmth. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.

Humidity

In Guatemala, the average relative humidity in June is 81%.

Rainfall

In June, the rain falls for 21.9 days. Throughout June, 75mm (2.95") of precipitation is accumulated. In Guatemala, during the entire year, the rain falls for 230.9 days and collects up to 812mm (31.97") of precipitation.

UV index

May through September, with an average maximum UV index of 7, are months with the highest UV index. A UV Index reading of 6 to 7 represents a high health hazard from exposure to the Sun's UV rays for average individuals.
Note: An average maximum UV index of 7 in June leads to these recommendations:
Shun overexposure. Protection from sun ravages is indispensable. Stay out of direct sunlight between 10 a.m. and 4 p.m., when UV radiation is most intense, and remember that not all shade structures provide complete protection. A hat with a broad brim is indispensable, filtering out up to half of UV rays.
