Temperature

Biru's October weather reaches an average high of 28.9°C (84°F) and an average low of 20.3°C (68.5°F), making it the warmest month.

Heat index

October's average heat index is computed to be a fiery hot 35°C (95°F). Extra precautions are necessary, heat cramps and heat exhaustion are plausible outcomes. Extended activity could lead to heatstroke.
It is emphasized that the heat index's values are meant for shaded zones with mild winds. The heat index has the possibility to be enhanced by 15 Fahrenheit (8 Celsius) degrees when there is direct sun exposure.
Note: The heat index, also known as 'apparent temperature' or 'feels like', represents the fusion of temperature and moisture in the air to suggest how warm it feels. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. Do note, being directly under sun rays can amplify the heat you feel, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance 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.
Perspiration and the resultant sweat evaporation are the body's natural thermostat, helping regulate temperature. Greater relative humidity lessens the rate of evaporation, thus decreasing the body's heat dispersal, which gives rise to a sensation of overheating. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.

January through December, with an average maximum UV index of 6, are months with the lowest UV index. A UV Index reading of 6 to 7 represents a high health hazard from unsafe exposure to UV radiation for ordinary individuals.
Note: In October, the maximum UV index of 6 transforms into these recommendations:
Stand by precautions and apply sun safety measures. Evading sunburn is of great importance. Stay in the shade and limit sun exposure from 10 a.m. to 4 p.m., when UV radiation is most potent. Keep in mind that shade structures like parasols or canopies do not offer full protection. Using UVA and UVB-protective sunglasses and sun-protective clothing is effective against UV radiation.
