Weather in June

A slight uplift of average high-temperatures is noted in June, with temperatures adjusting from a moderately hot 73.9°F (23.3°C) in May to a still warm 82.2°F (27.9°C). Wilsonville, during June nights, observes an average temperature of 65.5°F (18.6°C).Heat index
The heat index in June is calculated to be a hot 89.6°F (32°C). Persisting in activity during long-term exposure might induce weariness, with subsequent heat cramps.Be informed that the heat index values are oriented around shady conditions and gentle breezes. 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', blends air temperature and moisture content to represent the felt temperature to humans. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. In the direct sunlight, the weather's impact can be amplified, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Youngsters typically face more danger than adults since they sweat less. Their larger skin surface compared to their small bodies and heightened heat production from their activities augment their vulnerability.
