An easterly airstream affected the coast of Guangdong yesterday. Locally, there were cloudy periods and one or two light rain patches in the morning. It became fine and dry during the day. The relative humidity over many places fell to 60 per cent or below. With the easterly airstream now affecting the coast of Guangdong moderating gradually and under the influence of an settled weather system aloft, the weather is expected to be mainly fine and dry over southern China in the next couple of days. It will become very hot.

Green and yellow dots are swimming beaches; small dots show how much oxygen the sea holds for fish (blue is healthy, amber low, red too low). Bright red dots are red tides happening now, faded ones have passed. Beach and sea water readings from the Environmental Protection Department, red tide reports from the Agriculture, Fisheries and Conservation Department.
