March through April is spring in Macao, when it is humid, warm and wet. It is warm, and the average temperature during the day is 22 °C (72 °F). A T-shirt with long sleeves the best choice for comfort, though a light sweater at night to stay warm is worthwhile as the temperature drops a little. By April rainfall is up to 200 mm with a third of the days wet, and umbrellas needed. It’s a fine time to visit the Camões Grotto home to a 16th century poet and merchant, the grounds full of birds and colorful flowers forming the oldest and largest public park in Macao, an oasis amongst the bustle of the city.
