Weather in September
Temperature
During Sentinel's transition into September, the average high-temperature lessens, moving from a hot 94.1°F (34.5°C) in August to a moderately hot 85.1°F (29.5°C). In Sentinel, the expected average low-temperature for September is a refreshing 66°F (18.9°C).Heat index
The heat index value during September is computed to be a hot 89.6°F (32°C). A sense of exhaustion might occur with extended exposure and activity, potentially causing heat cramps.Heat index's context suggests values are appropriate for shady areas and slight breezes. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is a calculation that merges air temperature and relative humidity to depict the sensation of warmth. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. Exposure to direct sun rays can influence the heat you feel, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Youngsters are usually more at risk than adults, considering they sweat less. Additionally, their high skin surface area compared to their little bodies and their high heat production due to activity increases their risk.
