Guatemala, Cuba

Temperature

August stands out as Guatemala's warmest month, with an average high-temperature of 31.5°C (88.7°F) and a low-temperature of 23.3°C (73.9°F).

Heat index

The heat index in August is calculated to be a blistering 43°C (109.4°F). Mindful: Heat cramps and heat exhaustion are to be expected. Extended physical effort might result in heatstroke.
Remember that heat index calculations are made for conditions in the shade with light wind. Exposure to direct sunlight may make the heat index values climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', reflects the feeling of heat when considering both air temperature and humidity. The impact of weather is personal, differing among a variety of people based on differences in body mass, height, and the level of physical exertion. Under direct sun rays, the felt temperature might be heightened, with the heat index increasing by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
The body's innate mechanism to counteract overheating is through perspiration, as it leverages the cooling effects of sweat evaporation. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.

Humidity

In August, the average relative humidity in Guatemala is 80%.

Rainfall

In Guatemala, during August, the rain falls for 20.6 days and regularly aggregates up to 93mm (3.66") of precipitation. Throughout the year, in Guatemala, there are 230.9 rainfall days, and 812mm (31.97") of precipitation is accumulated.

Sunshine

The months with the most sunshine are July and August, with an average of 11.2h of sunshine.

UV index

May through September, with an average maximum UV index of 7, are months with the highest UV index. A UV Index estimate of 6 to 7 represents a high health risk from exposure to the Sun's UV rays for average individuals.
Note: A maximum high UV index of 7 in August translates into the following recommendations:
Incorporate safeguards and honour sun safety principles. Protection from skin and eye damage is obligatory. The Sun's UV radiation is at its strongest between the hours of 10 a.m. and 4 p.m. Minimize direct exposure to the sun during this period. For minimizing sun-related eye damage, always choose sunglasses with UVA and UVB coverage.
