The rainfall volume drops to 211mm (8.31") from the March peak, signalling a transition to the drier half of the year. Despite less rainfall, the relative humidity remains consistent, keeping the air moist. The sea temperature peaks at 30.3°C (86.5°F) in the month, making it ideal for diving and snorkeling.

Temperature

Stepping into April, Honiara records an average high-temperature of a still moderately hot 29°C (84.2°F), almost consistent with March. Throughout the nights in April, an average low-temperature of 23.9°C (75°F) is noted.

Heat index

The heat index value for April is evaluated at a sweltering 36°C (96.8°F). Implement additional preventive actions, heat cramps and heat exhaustion are potential hazards. Heatstroke could follow prolonged activity.
It is important to note that the heat index values are for shaded areas and light wind scenarios. 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 'felt air temperature', shows a temperature sensation when both heat and moisture conditions are combined. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. Always consider that direct sunlight exposure might heighten the heat's effects, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. With higher relative humidity, the rate of evaporation is reduced, resulting in increased heat retention in the body compared to drier air. Overheating dangers loom when the body's heat release mechanisms are overshadowed by excessive gain.

Humidity

January, March and April, with an average relative humidity of 85%, are the most humid months.

Note: The UV index of 7 during April translates into the following guidance:
Deflect overexposure. Sun protection is a necessity. The Sun's UV radiation is most intense from 10 a.m. to 4 p.m. Try to avoid direct sun exposure during these hours. Shield yourself from the harmful effects of UV radiation with sun-protective attire, a hat, and quality sunglasses. Beware! Reflections from sand and water can intensify the Sun's UV radiation.
