Sea Fog smothers parts of Newcastle
Tuesday, 27 February 2001
With relative humidity over 90% and temperatures
of around 25°C, added to the development of a sea fog in parts of Newcastle
today. Sea fog is regarded as very rare and is usually formed when humidity
levels are high combined with an onshore wind or sea breeze that blows
over a cool sea surface. The sea fog developed during the early
afternoon. At 3 pm, the temperature at Nobbys was 25.5°C with a humidity
of 96% and the winds blew from the ENE. The fog was very localised and
formed only on the coast such as Nobbys.
This kind of fog is rare in many parts of Australia.
They occur frequently in areas in northern California, USA and the west
coast of South America. They occur in these regions due to the cool
sea temperatures, high humidity and prevailing onshore winds, although
the air temperatures are usually cooler to what was experienced in Newcastle. back...
