October weather forecast
Granada, Nicaragua

While October experiences the heaviest rainfall amongst all months with a significant 353mm (13.9") over 29.2 days, it begins to showcase prominent signs of weather transition. The temperatures largely remain the same, and the relative humidity continues to remain high. An interesting aspect of October is the decrease in sunlight hours to 11.9, a decrease from the 12.2 hours in September. Despite the substantial rainfall, October represents a gradual shift towards the drier months awaiting.

Temperature

October, having an average high-temperature of 29.3°C (84.7°F) and an average low-temperature of 23.4°C (74.1°F), is the coldest month.

Heat index

In October, the heat index is evaluated at a very hot 37°C (98.6°F). Greater preventive actions are needed, heat exhaustion and heat cramps are likely. Persistent activity could provoke heatstroke.
Take into consideration that the heat index values are calculated for shade and light wind conditions. Facing direct sunlight may hike up the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is a single figure representing how weather conditions feel when combining temperature and humidity. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. Given direct exposure to sunlight, one might experience a rise in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
In high temperatures, perspiration kicks in, allowing the human body to cool down through the evaporation of sweat. Under high air temperature and high humidity (high heat index) conditions, the body's ability to perspire is compromised, increasing the sensation of heat. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.
