Weather in June
Temperature
Foster's transition into June sees a rise in the average high-temperature, advancing from a warm 78.4°F (25.8°C) in May to a hot 88.3°F (31.3°C). The low-temperature average for Foster during June stands at a pleasant 70.3°F (21.3°C).Heat index
For June, the heat index is evaluated at a fiery hot 100.4°F (38°C). More protective measures are required - heat exhaustion and heat cramps are likely. Heatstroke may follow lengthy activity.Be advised, the heat index considers values for conditions in shade and with a light breeze. Direct sunlight might cause an increase of up to 15 Fahrenheit (8 Celsius) degrees in the heat index.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is a value derived by merging air temperature with the humidity to convey how the climate feels. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. Understand that direct sun rays can influence the weather's impact, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
Through perspiration, the body has a natural mechanism to eliminate excessive heat via sweat evaporation. An increase in relative humidity disrupts body cooling by slowing the evaporation rate, thereby reducing the rate at which the body cools and amplifying the sense of heat. When the heat gained surpasses the body's cooling capacity, temperatures rise, signaling potential health concerns.
