Weather in June
Temperature
With the beginning of June, Vallecito's average high-temperature sees an increase, transitioning from a warm 73.4°F (23°C) in May to a still moderately hot 84.2°F (29°C). In Vallecito, the average temperature during the nights of June marks a significant drop from the daily high, settling at a mild 56.8°F (13.8°C).Heat index
The heat index value during June is calculated to be 84.2°F (29°C). Uninterrupted activity during exposure could lead to a sense of exhaustion, possibly causing heat cramps.Take note of the fact that heat index values are based on shaded circumstances with light airflows. Exposure to the direct sun might augment heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', melds the effects of warmth and moisture to generate a feeling of heat. The perception of temperature can be subjective, varying based on activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. It is essential to be conscious of the fact that direct sunlight can intensify the felt heat, leading to an elevation in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.

Also note that objects like parasols or canopies might not provide complete sun protection. Experience reduced UV exposure by about half when donning a wide-brim hat.
