Weather in May
Temperature
Palo Alto observes a slight uplift in the average high-temperature with the onset of May, adjusting from April's 78.6°F (25.9°C) to a still moderately hot 84.7°F (29.3°C). An average low-temperature of 66.2°F (19°C) is recorded during the nights in May in Palo Alto.Heat index
The heat index for May is calculated to be a fiery hot 95°F (35°C). Special measures are necessary to avoid heat cramps and heat exhaustion. Persistent activity could result in heatstroke.Take into consideration that the heat index values are calculated for shade and light wind conditions. Uninterrupted exposure to the sun may boost the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', determines the feeling of heat when you account for the relative humidity. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. One should be aware that direct sunshine can amplify the perceived temperature, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. Elevated relative humidity disrupts typical body cooling by reducing the evaporation rate, consequently decreasing the body's cooling rate and enhancing the feeling of heat. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.
