Wide-brimmed hats, sunglasses and light clothing were ubiquitous yesterday as people did their best to cope with the sweltering heat.
Along with yesterday's heat wave came a light smog. While the main pollutant early in the day was PM2.5 particles, this shifted in the afternoon to ozone, according to the meteorologists.
At its peak, the concentration of ozone was 168 micrograms per cubic meter, or 68 percent higher than the World Health Organization's recommended safe level of 100.
The bureau lifted the heat wave alert at 5:25pm, only to replace it an hour later with yellow alerts for rainstorms, gales and lightning.
Despite the warnings, which were based on expectations of the arrival of a south-moving rain belt, as of press time the city remained dry and warm.
Heavy rains remain on the cards for today and the weekend, however, while temperatures are set to range between 23 and 27 degrees.
The wet conditions are set to continue into next week, the bureau said.
