May weather forecastRio Bravo, Guatemala

Weather in May

May, the last month of the spring in Rio Bravo, is also a hot month, with temperature in the range of an average high of 30°C (86°F) and an average low of 20.5°C (68.9°F).

Temperature

The arrival of May denotes a barely perceptible change in the average high-temperatures to a still tropical 30°C (86°F) from April's 31.3°C (88.3°F). May's nights in Rio Bravo observe an average temperature of 20.5°C (68.9°F).

Heat index

May's heat index is estimated at a fiery hot 36°C (96.8°F). Implement additional preventive actions, heat cramps and heat exhaustion are potential hazards. Heatstroke could follow prolonged activity.
Data suggests that the heat index is set for environments in shade and with a light wind. Being exposed to direct sunshine might trigger a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is found by incorporating humidity levels into the air temperature measurement. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. 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 hold particular significance for children. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. In situations of high air temperature combined with high humidity (significant heat index), the body's ability to perspire is reduced, heightening the sense of warmth. Accumulating more heat than the body can dissipate leads to an uptick in body temperature, with potential heat stress consequences.

Humidity

In May, the average relative humidity in Rio Bravo is 74%.

UV index

The months with the highest UV index in Rio Bravo, Guatemala, are January through December, with an average maximum UV index of 6. January through December, with an average maximum UV index of 6, are months with the lowest UV index. A UV Index value of 6 to 7 symbolizes a high health vulnerability from exposure to the Sun's UV radiation for ordinary individuals.
Note: The UV index of 6 during May translates into the following guidance:
Avoid excessive sunlight. Those with lighter skin may experience burning in less than 20 minutes. Seek shade and limit direct Sun exposure between 10 a.m. and 4 p.m., when UV radiation is at its peak, but be aware that not all shade structures provide complete sun protection. 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.
