May brings about significant changes in the weather pattern in
Baucau. The onset of the dry season is unmistakable as rainfall decreases drastically. Temperatures tend to be somewhat cooler, especially during the early mornings and late evenings, yet the variation remains subtle. Despite the decrease in rainfall, the UV index remains high, demanding adequate sun protection. The reduced humidity provides a respite from the consistently high levels of the previous months, enhancing the overall comfort.
Temperature
The unfolding of May shows an average high-temperature of a still moderately hot 28.4°C (83.1°F), indicating a slight variance from
April's 28.8°C (83.8°F). During May, an average low-temperature of 20.5°C (68.9°F) is observed.
Heat index
For most parts of May, the heat index is computed to be a tropical 32°C (89.6°F). With constant exposure and activity, a state of weariness might ensue, leading to potential heat cramps.
The standards for the heat index are set for locations in shade and under light breezes. Exposure to the direct sun might augment heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is what the temperature feels like to the human body when the air temperature is combined with the relative humidity. Metabolic differences, pregnancy status, and the level of physical activity are additional factors influencing an individual's weather perception. Direct sun rays can make one feel hotter, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Youngsters typically face more danger than adults since they sweat less. Their larger skin surface compared to their small bodies and heightened heat production from their activities augment their vulnerability.
Humidity
The average relative humidity in May is 71%.
