April weather forecast
Singapore, Singapore

The weather in April continues Singapore's tropical trend, with relatively steady conditions. The minimal increase in rainfall makes it slightly wetter than March without causing any significant disruption. As the temperature continues its incremental increase, there's a simultaneous rise in sea temperatures, accounting for warmer swimming conditions.

As such, April remains a suitable period for leisurely exploration of the city-state.

Temperature

In Singapore, the month of April is known for its highest average temperatures, reaching a high of 31.7°C and a low of 24.4°C.

Heat index

During April, the heat index is computed to be a burning hot 45°C. Stay mindful: Heat exhaustion and heat cramps are likely. Heatstroke could follow extended physical effort.
It is crucial to understand that heat index figures are for shade and gentle wind conditions. Heat index values may rise by up to 15 Fahrenheit (8 Celsius) degrees when exposed to direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is an aggregate value of air's warmth and moisture to show the human-felt temperature. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. It is essential to be conscious of the fact that direct sunlight can intensify the felt heat, leading to an elevation in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. Under high air temperature coupled with high humidity (high heat index), the body's perspiration is reduced, intensifying the sensation of heat. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.

Note: In April, a regular UV index of 12 translates into these guidelines:
Ensure every crucial precaution is taken. Individuals with light skin could experience burns in under 5 minutes. Avoid exposure to the Sun and try to stay in the shade between 10 a.m. and 4 p.m., when UV radiation is most potent, but be aware that parasols or canopies may not offer full protection. Equip yourself with UVA and UVB-filtering sunglasses on clear, sunny days. Regardless of the cloudiness of the day, a sunscreen with SPF 30 or more should be applied and reapplied generously, specifically after swimming or outdoor exercise. Heed this! UV intensity is much stronger when reflected off sand and water.
