Weather in September

As September rolls in, Lombe begins to step out of its dry season with a slight increase in the number of wet days. A slight increase in precipitation signals a transition to October's wetter scenario. Alongside this, noticeable increments in the cloud cover give rise to softer sunlight. Significantly, the month experiences a slight increase in average rainfall up to 16mm (0.63") from the preceding dry months. Additionally, an observed increase in cloud cover up to 34% hints at the forthcoming rainy season.

Temperature

Lombe observes an average high-temperature of a still hot 31.4°C (88.5°F) in September, barely different from 32°C (89.6°F) in August. An average nighttime temperature of 19.5°C (67.1°F) is recorded in Lombe during September.

Heat index

For most parts of September, the heat index is estimated at a fiery hot 37°C (98.6°F). Implement more preventive measures, heat cramps and heat exhaustion are probable. Heatstroke might result from extended activity.
The metrics for the heat index are tailored for both shady environments and light winds. If directly exposed to the sun, the heat index could rise by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', arises from combining readings of air temperature and relative moisture content. The influence of weather is personal, with varied individuals experiencing it differently due to differences in body mass, stature, and physical exertion levels. Should you be directly under the sun, anticipate a possible increase in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. 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.
When temperatures rise, the human body turns to perspiration, using the cooling power of evaporating sweat. 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. When the heat gained surpasses the body's cooling capacity, temperatures rise, signaling potential health concerns.

The months with the lowest UV index are January through December, with an average maximum UV index of 6. A UV Index of 6 to 7 symbolizes a high health vulnerability from unprotected exposure to Sun's UV rays for the ordinary person.
Note: The maximum UV index of 6 during September leads to these instructions:
Adopt measures and apply sun safety strategies. Shielding from skin and eye damage is necessary. Stay in the shade and avoid direct Sun exposure from 10 a.m. to 4 p.m., a period when UV radiation is particularly strong, noting that parasols or canopies may not offer total sun protection. Safeguard your eyes, ears, and face from sun rays with the aid of a wide-brim hat.
