Weather in May
Temperature
With the onset of May, Seneca observes a minor temperature ascent, with the average high-temperature adjusting from April's 78.8°F (26°C) to a still moderately hot 85.3°F (29.6°C). Seneca's nighttime temperature during May is consistently averaged at a comfortable 64.4°F (18°C).Heat index
In May, the heat index is computed to be a fiery hot 95°F (35°C). Incorporate special precautions, risk of heat exhaustion and heat cramps is substantial. Sustained activity could cause heatstroke.Heat index data is primarily for areas with shade and subjected to light winds. The heat index has the potential to rise by 15 Fahrenheit (8 Celsius) degrees with direct sunshine exposure.
Note: The heat index, also known as 'apparent temperature' or 'real feel', gives a temperature feeling by integrating air temperature and humidity. The influence of weather is personal, with varied individuals experiencing it differently due to differences in body mass, stature, and physical exertion levels. 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 of high significance for children. Young children are generally more endangered than adults, as they usually less sweat. And also, due to larger skin surface relative to their small bodies and higher heat production as a result of their activity.
The body's inherent cooling system operates through perspiration, wherein evaporating sweat offsets excessive heat. An upsurge in relative humidity affects normal body cooling mechanisms by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. As the body accumulates more heat than it can release, body temperature goes up, increasing the risk of heat-related health issues.

Sunshine
In May, the average sunshine is 9.7h.UV index
In Seneca, the average daily maximum UV index in May is 6. A UV Index reading of 6 to 7 represents a high health hazard from unprotected exposure to Sun's UV rays for the average person.Note: In May, the UV index of 6 transforms into the following advice:
Skirt overexposure. People with light complexions might get scorched in under 20 minutes. Avoid direct Sun exposure and seek shade from 10 a.m. to 4 p.m., the period of highest UV radiation. Remember, however, that not all shade structures offer full protection. On bright days sunglasses that block both UVA and UVB rays should be worn. A hat with a wide brim is extremely helpful, as it can prevent roughly 50% of UV radiation from reaching the eyes.
