The icy weather did little to cool the ardour of the city's lovebirds as they celebrated the city's most romantic day in almost two decades.
As the Chinese and Western versions of Valentine's Day coincided - an event that had not happened for 19 years - some 493 couples were booked in for weddings with marriage registries, almost three times the 187 weddings that took place on February 14 last year.
At Wong Tai Sin Temple, about 200 couples sought the traditional blessing from the matchmaking deity Yue Lao for the Yuen Siu Festival, the Chinese equivalent of Valentine's Day.
Among the newlyweds yesterday were shop worker Leo Lee Ho-man, 24, and 23-year-old clerk Christy Ng Sin-tung.
"Today is a very special day, given the fact that the Western and Chinese Valentine's Days coincide," Ng said. "I'm sure it will add special meaning to our big day - and it will be easier for us to remember our anniversary!"
The pair took their vows at Cotton Tree Drive Marriage Registry in Central, in front of cheering friends and relatives. The bride said the low temperatures had not cooled her excitement on their big day.
Also saying "I do" were Fung Kwok-kuen, 40, and Chan Wing-sze, 26. Chan said a fortune teller had told their parents that yesterday was a "lucky day to get married" for them.
At Wong Tai Sin, couples paid tribute to the god who, Chinese lore has it, connects two lovers with a red thread so that they will never be apart. The lovebirds prayed and tied blessed "red strings of fate" on each other's wrists in front of the golden statue of Yue Lao.
And singles looking for love were not left out. Some 288 were invited to join a mass speed-dating event at Ocean Park.
They were chosen from more than 2,000 applicants from Hong Kong, Japan, Korea, Taiwan, the Philippines and Thailand who wanted to take part in the event organised by the theme park, the Hong Kong Tourism Board and a firm called Speed Dating Fever.
The first 48 pairs of singletons took part in three rounds of creative but romantic challenges around the park - including the rainforest and animal exhibits - in the hope of finding a partner in plenty of time for next year's Valentine's Day fun.
