Weather in September
Temperature
On the advent of September, Yimas's average high-temperature exhibits a minor adjustment to a still moderately hot 29.5°C (85.1°F) from August's 29.3°C (84.7°F). Yimas in September observes a slight diminution in temperature from daily highs, recording a low-temperature average of 24.6°C (76.3°F).Heat index
In September, the heat index is computed to be a torrid 36°C (96.8°F). Incorporate extra safety measures to avoid heat exhaustion and heat cramps. Continuous activity could provoke heatstroke.Data suggests that the heat index is set for environments in shade and with a light wind. The heat index has the potential to rise by 15 Fahrenheit (8 Celsius) degrees with direct sunshine exposure.
Note: The heat index, also known as 'real feel' or 'apparent temperature', combines air temperature and relative humidity to represent a human perceived temperature equivalent. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. Being under direct sunshine can magnify the heat experience, possibly pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Children frequently underestimate the necessity to rest and hydrate. Thirst is a late sign of dehydration - thus, it is vital to stay hydrated, particularly during lengthy physical exercises.
For the human body, perspiration is the go-to method to regulate temperature, using sweat's evaporation to dissipate warmth. With excessive moisture in the atmosphere, the effectiveness of the evaporation process is decreased, causing the body to cool down less efficiently, leading to a sensation of overheating. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.

In Yimas, the average relative humidity in September is 80%.Rainfall
September is the month with the least rainfall. Rain falls for 25.6 days and accumulates 136mm (5.35") of precipitation.Daylight

The months with the highest UV index are February, April through October, with an average maximum UV index of 7. A UV Index reading of 6 to 7 represents a high threat to health from exposure to the Sun's UV radiation for average individuals.Note: An average UV index of 7 in September transforms into this advice:
Enforce precautions and stick to sun safety measures. Preservation from skin and eye damage is essential. 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. Clothes that are both tight-knit and comfortably loose are prime choices for sun protection.
