Weather in May
Temperature
The shift into May is characterized by a subtle rise in the average high-temperature, transitioning from April's moderately hot 74.8°F (23.8°C) to a still warm 81.3°F (27.4°C). May's nights in Wilsonville observe an average temperature of 66°F (18.9°C).Heat index
Throughout May, the heat index is evaluated at a hot 86°F (30°C). Enduring exposure and unrelenting activity might cause a state of weariness, potentially leading to heat cramps.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 'apparent temperature' or 'feels like', is a measure of how hot it feels when the actual air humidity is factored in. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. When exposed to direct sunlight, it's possible for the heat index to increase by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
