October weather forecast
Talofofo, GU

October brings Talofofo into the heart of autumn with a substantial increase in wind speed from 9.9mph (15.9km/h) in September to 11.2mph (18km/h), reinforcing the changing weather environment. October shifts away from the warmth and humidity of summer, bringing forth an air of more relaxed, calm weather. The cooling trend aided by the slight rise in wind speeds imparts a refreshing change to the daily weather update. The UV levels remain consistent, coupled with a marginal increase in cloud cover from September, signifying a transition towards cooler months. Despite the rise in wind speed, October weather remains settled, easing Talofofo gently into the last quarter of the year.

Temperature

As October takes hold, the average high-temperature is a still moderately hot 84.4°F (29.1°C), nearly mirroring that of the previous month. The month of October is marked by an average minimum temperature of 82.6°F (28.1°C), slightly cooler than its daytime counterpart.

Heat index

The heat index for October is evaluated at a sweltering 95°F (35°C). More safety actions are required, heat exhaustion and heat cramps are probable. Long-term activity may precipitate heatstroke.
Take note of the fact that heat index values are based on shaded circumstances with light airflows. An exposure to direct sunlight may lift the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', arises from combining readings of air temperature and relative moisture content. An individual's perception of weather can be affected by a variety of elements including metabolic differences, being pregnant, and their level of physical exertion. Direct exposure to the sun's rays can enhance the felt temperature, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. 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.
Evaporation of sweat is the main factor behind the cooling effect of perspiration in the human body. With a high level of moisture in the air, the evaporation process becomes less efficient, preventing the body from cooling down efficiently and resulting in a sensation of overheating. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.
