Weather in July
Temperature
Brookline's July weather reaches an average high of 81.9°F (27.7°C) and an average low of 64.6°F (18.1°C), making it the warmest month.Heat index
The average heat index in July is computed to be a tropical 86°F (30°C). Staying active during long-term exposure might result in a state of exhaustion and cause heat cramps.Heat index values are typically calculated for conditions of shade and a light breeze. Being under direct sunlight might amplify the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', integrates the air's temperature and its humidity to showcase the felt temperature by people. The experience of temperature can be subjective, varying based on the individual's activity and heat perception, influenced by factors like wind, attire, and metabolic variations. Be aware that direct exposure to sunlight increases heat impact and may raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
