April in
Salvador signifies the arrival of peak rainfall season, emphasized by the city's lush, green landscapes.

Heat index
In April, the average heat index is calculated to be a tropical 34°C (93.2°F). Take greater precautions, heat exhaustion and heat cramps may be expected. Heatstroke could result from lengthy activity.
Note that heat index values are valued for light wind and location in the shade. Direct sunlight can cause a surge in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. Do note, being directly under sun rays can amplify the heat you feel, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.

Remember that UV radiation from the Sun is strongest between 10 a.m. and 4 p.m. Make an effort to limit direct sun exposure during this time. For excellent sun protection for the eyes, ears, face, and neck, consider a wide-brim hat. 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. Warning! Reflective surfaces like sand and water amplify the Sun's UV radiation.
