Here is the latest weather bulletin issued by the Hong Kong Observatory.

A dry northeast monsoon brought fine weather to southern China today. Locally, it was fine and very dry. The relative humidity over most parts of the territory stayed at 40 per cent or below in the afternoon. The northeast monsoon will continue to bring fine and very dry weather to southern China in the next couple of days, and the temperature difference will be rather large between day and night over the region.

Besides, Severe Typhoon Kong-rey weakened into a typhoon this morning. At 11 p.m., Kong-rey was centred about 130 kilometres west of Okinawa. It is forecast to move north-northwest at about 25 kilometres per hour across the Ryukyu Islands and the East China Sea.

Weather forecast for Hong Kong (Friday, 5 Oct 2018)

Fine and very dry. The minimum temperature will be about 23 degrees in the urban areas, and a few degrees lower in the New Territories. The maximum temperature will be around 30 degrees. Moderate northerly winds, occasionally fresh.

Note

      

    1. From readings taken at various locations in Hong Kong in the
past, the hourly mean ambient gamma radiation dose rate may
vary between 0.06 and 0.3 microsievert per hour. (1
microsievert = 0.000001 sievert = 0.001 millisievert)

    2. Temporal variations are generally caused by changes in
meteorological conditions such as rainfall, wind and
barometric pressure.

    3. Spatial variations are generally caused by differences in
the radioactive content of local rock and soil.

    4. The data displayed is provisional. Only limited data
validation has been carried out.
