Weather in April

Steadying from a wet March, Lombe's weather in April transitions to a drier and cooler mood, setting prospects for a dry and cooler May to come. The declining trend of UV index values continues from previous months. Despite the overall relatively cooler temperatures, April remains a moderately humid month. Make note of a significant leap in rain measurement to an impressive 219mm (8.62"). While cloud cover remains high, a small shift in atmospheric pressure can be discerned, averaging at 1011.7mb.

Temperature

Lombe greets April with an average high-temperature of a still moderately hot 29.3°C (84.7°F), marking a slight deviation from the preceding month. April witnesses an average nighttime temperature of 20.1°C (68.2°F).

Heat index

In April, the average heat index is estimated at a very hot 37°C (98.6°F). More preventive actions are needed, risk of heat exhaustion and heat cramps is significant. Prolonged activity may trigger heatstroke.
Be informed that the heat index values are oriented around shady conditions and gentle breezes. Direct sunlight might cause an increase of up to 15 Fahrenheit (8 Celsius) degrees in the heat index.
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. Depending on the activity and the individual's heat perception, which may vary due to factors including wind, clothing, and metabolic variations, this effect remains subjective. With the sun shining directly, it's crucial to understand that it can increase the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
When temperatures rise, the human body turns to perspiration, using the cooling power of evaporating sweat. When the level of relative humidity is elevated, evaporation diminishes, causing more warmth to be retained in the body than in dry air. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.

Humidity

The months with the highest humidity are April and December, with an average relative humidity of 86%.

UV index

The months with the highest UV index are January through December, with an average maximum UV index of 6. The months with the lowest UV index are January through December, with an average maximum UV index of 6. A UV Index estimate of 6 to 7 represents a high health risk from unsafe exposure to UV radiation for average individuals.
Note: The UV index of 6 in April translates into these instructions:
Prevent overexposure. Protection from the sun's harmful effects is needed. Make an effort to avoid direct sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation, and note that objects like parasols or canopies might not offer full sun protection. Shield yourself from the harmful effects of UV radiation with sun-protective attire, a hat, and quality sunglasses.
