May weather forecast
Pomona, Guyana

The last month of the spring, May, is another tropical month in Pomona, Guyana, with an average temperature varying between 30.5°C (86.9°F) and 23.1°C (73.6°F).

Temperature

May's average high-temperature stands at a still tropical 30.5°C (86.9°F), showing little deviation from April's 30.8°C (87.4°F). Pomona experiences a nighttime temperature average of 23.1°C (73.6°F) during May.

Heat index

May's mean heat index is estimated at a blisteringly hot 40°C (104°F). Incorporate extra safety measures to avoid heat exhaustion and heat cramps. Continuous activity could provoke heatstroke.
Heat index determinations are made taking into account the shade and light air movements. Exposure to direct sunshine can increase heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is a measure that combines air temperature and relative humidity into a single value that indicates how hot the weather feels. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. Remember, direct sunlight exposure can heighten the heat impact and might increase the heat index by 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. An increase in relative humidity disrupts body cooling by slowing the evaporation rate, thereby reducing the rate at which the body cools and amplifying the sense of heat. When the heat gained surpasses the body's cooling capacity, temperatures rise, signaling potential health concerns.

Note: An average maximum UV index of 6 in May leads to these recommendations:
Avoid excessive sunlight. Those with lighter skin may experience burning in less than 20 minutes. Avoid direct sunlight between the hours of 10 a.m. and 4 p.m., when UV radiation is at its peak. Keep in mind that shade structures may not provide complete protection. On sunny days, it's ideal to wear sunglasses that filter out UVA and UVB rays.
