Lancaster, Guyana

November, the last month of the autumn in Lancaster, is another tropical month, with temperature in the range of an average low of 22.5°C (72.5°F) and an average high of 32.6°C (90.7°F).

Temperature

With the arrival of November, Lancaster's average high-temperature registers at a still hot 32.6°C (90.7°F), indicating a subtle variation from the previous month. November witnesses an average nighttime temperature of 22.5°C (72.5°F).

Heat index

Throughout November, the heat index is calculated to be a blazing hot 47°C (116.6°F). Caution: Heat cramps along with heat exhaustion are expected. Sustained activity could lead to heatstroke.
Note that heat index values are valued for light wind and location in the shade. Uninterrupted exposure to the sun may boost the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is a composite of temperature and humidity figures to convey how warm it feels. An individual's perception of weather can be influenced by a variety of factors including metabolic differences, being pregnant, and their degree of physical exertion. 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 are of high significance for children. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. In situations of high air temperature combined with high humidity (significant heat index), the body's ability to perspire is reduced, heightening the sense of warmth. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.

UV index

June through November, with an average maximum UV index of 7, are months with the highest UV index. A UV Index value of 6 to 7 symbolizes a high health hazard from unprotected exposure to Sun's UV rays for ordinary individuals.
Note: In November, the maximum UV index of 7 translates into these guidelines:
Use protective steps and abide by sun safety guidelines. Safeguarding against skin and eye harm is necessary. UV radiation from the sun is at its strongest between 10 a.m. and 4 p.m. Try to limit direct exposure during these hours. A wide-brimmed hat is a shield, deflecting up to 50% of harmful UV radiation from eyes.
