Weather in May

May, the last month of the spring in Port Tampa, is another warm month, with temperature in the range of an average low of 71.4°F (21.9°C) and an average high of 85.8°F (29.9°C).

Temperature

The transition from April to May brings an average high-temperature of a still warm 85.8°F (29.9°C), barely different from April's 81.7°F (27.6°C). Nighttime temperature lowers to an average of 71.4°F (21.9°C) in May.

Heat index

In May, the heat index is calculated to be a torrid 95°F (35°C). Exercise enhanced safety steps, heat cramps and heat exhaustion are probable. Heatstroke could be a result of sustained activity.
In reference to the heat index, it's for places in shade and with a slight wind. Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', unifies temperature and humidity readings to offer a comprehensive feel of warmth. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. It is important to note that direct sunlight can intensify the weather impact, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
In the face of high temperatures, the human body's reflex is to perspire, leveraging sweat evaporation for cooling. In circumstances of high air temperature and humidity (high heat index), the body's perspiration is restricted, heightening the feeling of warmth. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.

Fend off overexposure. Sun protection is vital. Be aware that the sun's UV radiation is strongest between 10 a.m. and 4 p.m. and try to reduce direct sun exposure during this period as much as possible. Sun-protective clothing, a long-sleeved shirt and pants, a wide-brimmed hat, and UVA and UVB-blocking sunglasses are particularly helpful in blocking UV radiation's harmful effects.
