Spring begins by March and brings temperate weather with the average temperatures in the agreeable 17.2°C (63°F) to 21.1°C (70°F) range. Northern cold winds are sometimes active in spring, but it is unusual for the thermometer to register sub 11.1°C (52°F) temperatures.
Fog is likely in early mornings as the clouds cover the sun for long periods to the extent that the daily sunshine reduces to 3 hours. March registers 76.2mm (3") of rain with an average of 10 rainy days, but it is generally light to moderate and does not pose a threat to tours and excursions.
Hong Kong International Film Festival is an exciting event for film lovers, but it is better to wear at least a light raincoat, while outdoors. March mornings are pleasant to stroll along the waterfront at the Tsim Sha Tsui Promenade with a splendid view of the spectacular skylines of Hong Kong.
