Weather in October
Temperature
The advent of October sees the average high-temperature at a still tropical 30.9°C (87.6°F), subtly shifted from September's 31.2°C (88.2°F). The average low-temperature, in October, is a pleasant 21.8°C (71.2°F).Heat index
The heat index in October is evaluated at a blistering 40°C (104°F). Ensure additional precautions, heat exhaustion and heat cramps may be expected. Heatstroke could occur from sustained activity.Note that heat index values are valued for light wind and location in the shade. A rise of up to 15 Fahrenheit (8 Celsius) degrees in the heat index could result from direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', arises from combining readings of air temperature and relative moisture content. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. Sunshine, when direct, has the potential to intensify weather effects, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
When temperatures rise, the human body turns to perspiration, using the cooling power of evaporating sweat. When the air contains significant moisture, the efficiency of the evaporation process decreases, preventing the body from cooling down effectively and creating a feeling of overheating. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.

The months with the lowest UV index are January, February, October through December, with an average maximum UV index of 6. A UV Index value of 6 to 7 symbolizes a high health vulnerability from unsafe exposure to UV radiation for the average person.Note: A maximum high daily UV index of 6 during October translates into the following directions:
Dodge overexposure. Fair-skinned people can get singed in less than 20 minutes. Minimize exposure to direct sunlight and seek shade from 10 a.m. to 4 p.m., when UV radiation is most intense, but remember that shade structures may not offer complete protection. Employ a wide-brim hat for potent defense against up to 50% of UV rays.
