Unseasonal humid weather has given a huge boost to sales of dehumidifiers.
Retailers say sales are two to three times above normal for this time of year, with many models already out of stock.
A humid airstream last month sent the average humidity soaring to 86 per cent compared with the more-usual 79 per cent experienced at the same time last year.
While the present humid weather - 75 to 95 per cent today and tomorrow - will moderate over the weekend when a northeast monsoon arrives, 'the humid weather will be back next week, with fog returning', an Observatory spokesman said.
Forecasters are tipping 80 to 95 per cent humidity next week. Although such levels are not particularly high for March, the early arrival of the humid weather in February sent householders rushing to appliance stores.
Department store Sogo said dehumidifier sales were almost triple their usual levels because of the humid weather.
