May weather forecast
Alachua, FL

May, the last month of the spring in Alachua, is a tropical month, with an average temperature varying between 86.2°F (30.1°C) and 66.7°F (19.3°C).

Temperature

May brings a slight elevation in the average high-temperature, transitioning from April's warm 80.6°F (27°C) to a hot 86.2°F (30.1°C). Alachua's average low-temperature during May nights is observed to be an enjoyable 66.7°F (19.3°C).

Heat index

The heat index value for May is computed to be a torrid 96.8°F (36°C). Special measures are necessary to avoid heat cramps and heat exhaustion. Persistent activity could result in heatstroke.
Remember that heat index calculations are made for conditions in the shade with light wind. The heat index might be elevated by 15 Fahrenheit (8 Celsius) degrees due to direct sun exposure.
Note: The heat index, also known as 'real feel' or 'feels like', is what the temperature feels like to the human body when the air temperature is combined with the relative humidity. This effect is personal, influenced by the individual's physical activity and heat sensitivity, shaped by factors including wind, attire, and metabolic variations. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. With higher relative humidity, the rate of evaporation is reduced, resulting in increased heat retention in the body compared to drier air. The body is at risk of dehydration and related complications when it fails to shed excessive heat.

UV index

The months with the highest UV index are May through August, with an average maximum UV index of 7. A UV Index reading of 6 to 7 represents a high health vulnerability from unsafe exposure to UV radiation for average individuals.
Note: In May, the UV index of 7 transforms into the following advice:
Avoid overexposure. Fair-skinned individuals can burn in under 20 minutes. Limit your direct sun exposure, especially between 10 a.m. and 4 p.m., when UV radiation is strongest. Shade structures might not provide complete sun protection. For optimum UV protection, wear sun-resistant attire complemented with a hat and quality shades.
