Weather in May
Temperature
Callaghan's weather in May indicates an average high-temperature of a still tropical 93.2°F (34°C), nearly consistent with the 88°F (31.1°C) of April. During May nights, Callaghan records an average temperature of 73°F (22.8°C).Heat index
During May, the heat index is evaluated at a blisteringly hot 107.6°F (42°C). Incorporate extra safety measures to avoid heat exhaustion and heat cramps. Continuous activity could provoke heatstroke.Observations indicate that the heat index values are for shady locations with light wind. Uninterrupted exposure to the sun may boost the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is a fusion of air temperature and moisture levels to demonstrate the sensation of heat. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. With the sun shining directly, it's crucial to understand that it can increase the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
When the body gets too warm, it perspires, leading to sweat evaporation which cools it down. In the presence of high relative humidity, the evaporation rate diminishes, resulting in the body retaining more warmth compared to dry conditions. Overheating can ensue when the body accumulates more heat than it can release, and dehydration severity may vary.
