September weather forecast
La Gomera, Guatemala

The first month of the autumn, September, is still a tropical month in La Gomera, Guatemala, with an average temperature fluctuating between 32°C (89.6°F) and 24.5°C (76.1°F).

Temperature

In September, La Gomera experiences a barely noticeable shift in meteorological conditions, with average high-temperatures moving from 32.6°C (90.7°F) in August to a still hot 32°C (89.6°F). During the nights in September, an average low-temperature of 24.5°C (76.1°F) is observed.

Heat index

September's average heat index is estimated at a blisteringly hot 42°C (107.6°F). Emphasize additional safety, risk of heat cramps and heat exhaustion is high. Continuous activity might result in heatstroke.
From a standpoint of the heat index, values pertain to shaded conditions and mild breezes. The presence of direct sunlight can raise the heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', reflects the feeling of heat when considering both air temperature and humidity. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. Awareness of direct sun exposure is crucial as it has the potential to heighten the weather's effects, pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
One of the main methods the human body employs to cool down is by perspiring, as this process allows sweat to evaporate and remove excess heat. Increased relative humidity interferes with body cooling by slowing the rate of evaporation, resulting in a slower body cooling rate and a heightened feeling of heat. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.

A UV Index value of 6 to 7 symbolizes a high health vulnerability from unprotected exposure to Sun's UV rays for the average person.
Note: The maximum daily UV index of 7 during September translates into the following directions:
Skirt overexposure. People with light complexions might get scorched in under 20 minutes. Stay in the shade and limit direct sun exposure between 10 a.m. and 4 p.m., when UV radiation is at its strongest. Remember, however, that not all shade structures provide full sun protection. Tightly woven clothing, when worn loosely, shields effectively against the Sun.
