Weather in May
Temperature
May witnesses a subtle temperature ascent, adjusting from 74.1°F (23.4°C) in April to a still warm 81.7°F (27.6°C). During May, Modoc's temperature averages to a comfortable 61.5°F (16.4°C) at night.Heat index
During May, the heat index is calculated to be a tropical 86°F (30°C). Remaining active during long-lasting exposure could cause fatigue, leading to heat cramps.Note that heat index values are valued for light wind and location in the shade. Direct exposure to sunshine could lead to a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', offers an insight into how hot it feels when we factor in moisture content. An individual's perception of weather can be affected by a variety of elements including metabolic differences, being pregnant, and their level of physical exertion. Keep in mind that direct sunshine exposure can amplify the weather's effects, possibly increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
