April weather forecast
Port Sudan, Sudan

April embeds itself as a noticeably warmer month with substantially high sunlight exposure. Equally remarkable is the plunge in relative humidity down to 65%, a noticeable shift from the more humid start of the year. Ocean waters are comfortably warm, perfect for swimming or boating activities. Clear skies are punctuated rarely by rainfall lending to prolonged periods of sun. Consequently, May is expected to sustain the trend of warming temperatures and long, dry days.

Temperature

Heat index

The heat index value for April is appraised at a very hot 37°C (98.6°F). Ensure extra safety measures, heat exhaustion and heat cramps are likely. Continuous activity might result in heatstroke.
Evaluating the heat index requires understanding its values in the shade and with gentle winds. Being under direct sunlight might amplify the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', reflects the blend of air temperature and relative humidity to give a temperature impression. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. When in direct sunlight, one should be cautious as it can raise the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. A surge in relative humidity can disrupt the body's normal cooling function by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. Overheating and potential dehydration arise when body heat gain eclipses its release capability.

Humidity

The average relative humidity in April is 65%.

Take all necessary precautions, as unprotected skin can burn in minutes. Stay out of direct sunlight between 10 a.m. and 4 p.m., when UV radiation is most intense, and remember that not all shade structures provide complete protection. In bright sunlight, prioritize sunglasses that grant protection from UVA and UVB radiation. Even on overcast days, a sunscreen with a sun protection factor of no less than 30 should be generously applied and reapplied, particularly after swimming or outdoor activities. Alert! Sand and water increase UV exposure due to their reflective properties.
