Weather in April

April maintains the high temperatures seen in March but brings a decrease in precipitation making Lobito weather somewhat dryer. Still, the humidity is consistent with the previous month ensuring the warm and moist climate sustained. Despite being one of the hotter months, the warmth of the sea notably drops in April. Changes like these indicate a transition period in Lobito, as conditions begin to prepare for the mid-year season. Meanwhile, sunshine hours have reduced compared to earlier months.

Temperature

April registers as the month with the highest average temperatures, reaching 29.8°C (85.6°F) at its peak and 25°C (77°F) at the lowest.

Heat index

In April, the heat index is evaluated at a sweltering 36°C (96.8°F). Undertake special precautions, the probability of heat exhaustion and heat cramps is high. Prolonged activity may provoke heatstroke.
One should consider that heat index numbers are for shaded settings and light wind. Exposure to the direct sun might augment heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is an aggregate value of air's warmth and moisture to show the human-felt temperature. Elements such as metabolic variations, pregnancy, and physical exertion can influence one's weather perception. Consider the fact that direct sun exposure can influence how hot one feels, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
Perspiring is how the human body naturally cools down, as sweat's evaporation takes away excess heat. With higher relative humidity, the rate of evaporation is reduced, resulting in increased heat retention in the body compared to drier air. Accumulating more heat than the body can dissipate leads to an uptick in body temperature, with potential heat stress consequences.

Humidity

In April, the average relative humidity is 75%.

Take precautions and adopt sun safety practices. Protection against sunburn is obliged. Stay in the shade and avoid direct Sun exposure from 10 a.m. to 4 p.m., a period when UV radiation is particularly strong, noting that parasols or canopies may not offer total sun protection. A hat with a generous brim can prevent nearly 50% of UV rays from reaching your eyes. Note! The Sun's UV radiation gets intensified with the reflection from sand and water.
