Trev’s Brisbane Forecast for next 7 Days from 5 October PLUS

The Seabreeze Effect – Do the coastal areas always stay cooler?

“Brisbane has recorded its hottest October day since 2004, with the temperature today hitting 36.6 degrees earlier this afternoon. The Bureau of Meteorology says temperatures across the south-east were between five and 10 degrees above average. Senior forecaster Felim Hanniffy says the heat was the result of a trough travelling towards the coast — from an area just west of the Darling Downs — and northerly winds.” (Source: ABC news 4/10/21)

Can this heat reach the coastal areas like the bayside suburbs of Redcliff and Sandgate or Wellington Point and Cleveland? The answers is yes. This can occur when the sea breeze effect is weakest, or non-existent, and hot north-westerly winds predominate. It is most likely to occur around February when bay water temperatures reach their maximum and winds swing to the north-west as a tough line passes to the east over the south-east corner of the state. I’ve observed this many times over the past 20 years of living at Wellington Point. Temperatures can then reach the low 40s, similar to Ipswich. The difference with suburbs further inland from the coast is that it happens far less often to coastal suburbs. So most of the time bayside suburbs are cooler, but not always, as most people assume.

This coming week is looking pretty similar to last week, but with less chance of rain from a storm until Monday. Another trough system is moving across from the west. Minimum temperatures mid- week are predicted to be around 14 degrees Celsius with maximums rising to around 30 degrees Celsius by the weekend. Winds will be generally light to moderate north-easterlies, stronger in the afternoon due to the sea breeze effect.

Take your sunscreen and hat and enjoy the great weather. Listen for any storm warnings or watch the Bureau of Meteorology radar and warnings on your mobile phone at the weekend. It’s free and very useful.

See ya next week. Trev the Weatherman
