Weather in July

Despite marginally lowered wind speeds and a gradual rise in temperatures, July's climate cultivates long, languid days followed by warm, quiet nights. Temperatures remain steady, accompanied by consistent UV levels, making July a feasible option for outdoor enthusiasts in Talofofo. The slight increase in rainfall amid steady weather parameters extends the notion of balmy summer days well into July. Consequently, even amidst summer, the pleasantly balanced weather of Talofofo continues its habitual consistency.

Heat index

The heat index value for July is evaluated at a fiery hot 95°F (35°C). Use additional protective measures, heat cramps and heat exhaustion are possible outcomes. Continuous activity might lead to heatstroke.
Consider that heat index readings are for situations in the shade and light wind. If directly exposed to the sun, the heat index could rise by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', gives an indication of how one might feel in terms of heat after considering humidity. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. Being aware that direct sunlight can impact the felt heat might mean an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
To combat high temperatures, the human body perspires and relies on sweat evaporation for cooling. When the relative humidity is high, the evaporation rate is reduced. The warmth is removed from the body at a lower rate, causing the body to retain more heat than it would in dry air. Heat disorders may be on the horizon when body temperatures rise from inadequate heat management.
