Weather in June

June, the first month of the summer in Seneca, is a hot month, with an average temperature varying between 64.9°F (18.3°C) and 86.5°F (30.3°C).

Temperature

June witnesses a minor rise in the average high-temperature, transitioning from a moderately hot 78.8°F (26°C) in May to a hot 86.5°F (30.3°C). A steep decline to an enjoyable 64.9°F (18.3°C) characterizes the June nights.

Heat index

In June, the heat index is computed to be a fiery hot 96.8°F (36°C). Use additional protective measures, heat cramps and heat exhaustion are possible outcomes. Continuous activity might lead to heatstroke.
Data suggests that the heat index is set for environments in shade and with a light wind. 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 'apparent temperature', joins air temperature with relative humidity to produce a temperature perception for humans. The impression of weather on a person can be swayed by additional aspects, including metabolic variations, pregnancy, and activity levels. Should you be directly under the sun, anticipate a possible increase in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Younglings frequently fail to recognize the requirement to rest and rehydrate. Thirst emerges late in dehydration - it is imperative to keep hydration levels high, particularly during extended physical exertions.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. Heightened relative humidity interferes with the body's usual cooling mechanism by reducing evaporation, subsequently decreasing the body's cooling rate and increasing the sensation of heat. Heat-related disorders may develop if heat gain in the body overshadows its cooling capacity, leading to elevated temperatures.
