May weather forecast
Lombe, Angola

May stands out as a month of transition, marking the end of the rainy season and the start of clear skies and lower humidity in Lombe. This month’s weather patterns take a noticeable shift from the high precipitation values in April to usher in the bold and sun-drenched character of May. A winding down of the rainfall intensity paves the way for a drier June. In a pivotal twist, May's remarkable decrease in rainfall to 60mm (2.36") unfolds prominently. Moreover, the drop in relative humidity to 75% gives a drier feel to the atmospheric condition.

The commencement of May brings an average high-temperature of a tropical 30.9°C (87.6°F), marking an inconsequential divergence from April. May nights are characterized by a significant departure from the daytime highs, dropping to an average temperature of 18.8°C (65.8°F).

Heat index

In May, the average heat index is estimated at a sweltering 39°C (102.2°F). Implement enhanced safety actions, heat cramps and heat exhaustion could occur. Sustained activity might result in heatstroke.
In terms of the heat index, values are set with light wind and shade conditions in mind. Exposure to the direct sun might augment heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is an aggregate value of air's warmth and moisture to show the human-felt temperature. This impact is subjective, influenced by the person's physical activity and individual heat perception, affected by factors including wind, attire, and metabolic differences. Understand that direct sun rays can influence the weather's impact, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. 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 innate cooling system of the human body revolves around perspiration, with the evaporation of sweat being central to this process. In the presence of abundant moisture in the atmosphere, the cooling process through evaporation is hindered, causing the body to feel excessively warm. When heat surpasses the body's release mechanisms, dehydration and overheating risks become pronounced.

Refrain from overexposure. Fair-skinned individuals could burn in under 20 minutes. Limit direct sun exposure and seek shade between 10 a.m. and 4 p.m., the time of the most intense UV radiation, noting that shade structures may not provide total sun protection. A wide-brimmed hat is a shield, deflecting up to 50% of harmful UV radiation from eyes.
