May weather forecast
Big Creek, Belize

May in Big Creek, Belize, is characterized by increased humidity levels and higher rainfall, reshaping the tranquil weather experienced in April. With a higher level of rainfall, 105mm (4.13") to be precise, the month distinguishes itself as the onset of the wet season. Despite the increase in rains, the warm climate remains stable, manifesting in warmer nights and generous hours of daylight. The shift from April's somewhat drier climate results in a predominant amassment of clouds. The transition into the next month brings along higher temperatures and rainfall, marking the arrival of the full-fledged monsoon period.

Temperature

The arrival of May brings an average high-temperature of a still hot 31.1°C (88°F), nearly identical to April's 31°C (87.8°F). Throughout May, Big Creek encounters an average temperature drop to a moderately hot 24.3°C (75.7°F).

Heat index

For May, the heat index is estimated at a blisteringly hot 41°C (105.8°F). Preventive measures are required to mitigate the risk of heat cramps and heat exhaustion. Continuous activity may precipitate heatstroke.
Heat index readings emphasize conditions of light breezes and shaded spots. If directly exposed to the sun, the heat index could rise by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', evaluates the perceived heat by adding the effect of moisture in the air. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values hold particular importance for children. Kids are usually in more danger than grown-ups as they tend to sweat less. Plus, their bigger skin surface in relation to their small frames and increased heat generation due to their activity level make them more susceptible.
Perspiring is a crucial mechanism for the human body, allowing it to release excessive warmth through evaporating sweat. When relative humidity is heightened, it slows the rate of evaporation, thereby decreasing the body's ability to shed heat and creating a sensation of overheating. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.

Humidity

In May, the average relative humidity is 78%.

Note: The daily maximum UV index of 7 in May interprets into the following advice:
Ward off overexposure. Defence against solar harm is crucial. UV radiation from the sun is at its strongest between 10 a.m. and 4 p.m. Try to limit direct exposure during these hours. Shield yourself from the harmful effects of UV radiation with sun-protective attire, a hat, and quality sunglasses. Stay vigilant! UV rays get a boost in intensity due to sand and water reflections.
