September weather forecast
Ughelli, Nigeria

The first month of the autumn, September, is also a moderately hot month in Ughelli, Nigeria, with an average temperature varying between 23.5°C (74.3°F) and 29°C (84.2°F).

Temperature

Ughelli observes a minor difference in average high-temperatures between August's 28.5°C (83.3°F) and September's 29°C (84.2°F). Throughout September, Ughelli registers a consistent average low-temperature of 23.5°C (74.3°F).

Heat index

During September, the heat index is computed to be a torrid 36°C (96.8°F). Exercise more precautions, heat cramps and heat exhaustion are potential risks. Continuous activity could precipitate heatstroke.
Take into consideration that the heat index values are calculated for shade and light wind conditions. Being exposed to direct sunshine might trigger a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is an amalgamation of air temperature and humidity to express the equivalent perceived temperature. Metabolic differences, pregnancy status, and the level of physical activity are additional factors influencing an individual's weather perception. It is noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
In high temperatures, perspiration kicks in, allowing the human body to cool down through the evaporation of sweat. An upsurge in relative humidity affects normal body cooling mechanisms by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. Accumulating more heat than the body can dissipate leads to an uptick in body temperature, with potential heat stress consequences.

Persist in precautions and follow sun safety policies. Keeping sunburn at bay is imperative.

Sun protection is enhanced with clothing that boasts a tight weave yet offers a loose fit.
