Weather in October

October in Waterloo marks a further decline in rainfall, hitting 151mm (5.94"), setting a clear departure from the preceding wet months. Lower precipitation levels lead to increased sunshine hours, indicating brighter days ahead. The competition between dissipating monsoon clouds and gathering sunny spells is evident. Wind speeds begin to decrease from levels observed over previous months. This lessening of rain and increase in sunshine is a clear sign of approaching November's drier conditions.

When assessing, remember that heat index measurements are for light winds and shaded spots. Direct exposure to sunshine could lead to a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', determines the feeling of heat when you account for the relative humidity. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. Direct sunlight can potentially raise the heat index by 15 Fahrenheit (8 Celsius) degrees, so it's crucial to consider. Heat index values are particularly relevant to children. Kids are usually in more danger than grown-ups as they tend to sweat less. Plus, their bigger skin surface in relation to their small frames and increased heat generation due to their activity level make them more susceptible.
Perspiration is the body's default response to elevated temperatures, as it promotes the evaporation of sweat to achieve cooling. An upsurge in relative humidity affects normal body cooling mechanisms by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. Excessive heat that's not properly managed leads to increased body temperatures and resultant health issues.
