Coffs Harbour Forecast Meteograms
About Weatherzone Meteograms
Meteograms are a means of displaying a computer model forecast for a certain point within the domain over which the model runs. They compliment charts which show output over the whole domain (or part of the domain) for one time step.
Roll over the vertices on the meteograms with your mouse to see numeric values.
The GFS model output comes at a resolution of 1° meaning many places with relatively different climates may lie within the same grid cell.
A computer model operates by dividing the atmosphere into grid cells which may be quite large so it's important to factor the spatial resolution of the model into your interpretation of the output (see below).
In addition, different models output data for different time steps. Using a model with an output time interval of 6 hours a temperature of 20° at analysis time and a predicted temperature of 15° six hours later will be displayed with a line between the two but of course there may be fluctuations between those times (a spike to 25°, for example) which will not be reflected.
A meteogram shows the general nature of what may be experienced within the area in which the point lies, over time. Some local knowlegde (the likely effects of elevation and terrain in a certain weather pattern, for example) will help you refine this guidance.

Warmest night in decades for parts of WA
13:24 AEDT After a searing hot day, Western Australians sweltered through a near record warm night last night. The uncomfortable days and nights are being caused by extremely hot and dry easterly winds flowing over the west coast in response to Severe Tropical Cyclone Sean. Image: 850hPa temperature and wind at 8pm AWST on Monday, January 20 showing clockwise winds around Severe Tropical Cyclone Sean dragging a hot airmass from Australia’s interior all the way to the west coast. This is causing a severe to extreme heatwave to impact southwestern WA, with Geraldton equalling its highest record temperature of 49.3°C on Monday, meanwhile Perth airport hit 44.7°C and the city 43.6°C. After an extremely hot day, temperatures remained in the mid to high 30s across the southwest of the state until around 8pm before finally dropping into the high 20s after midnight. For some locations in western WA Monday night was the warmest in decades; Mandurah’s minimum dropped to 28.4°C which equals the record set in 1968. Bickley a western suburb of Perth recorded a minimum of 27.1°C, which is the warmest night in at least 30 years. Perth’s temperature dropped to a warm 27.2°C, 9°C above average and only 2.5°C off the record. The severe to extreme heatwave is set to continue across large parts of WA for the next three days, with temperatures forecast to reach the high 30s to low 40s.
