Where does our weather information come from?

Weatherzone  utilises weather information from a variety of quality sources, including our own market-leading Opticast forecast system and advanced total lightning network. Additional information is also included from trustworthy sources such as the Australian Bureau of Meteorology and the Joint Typhoon Warning Centre.

Weatherzone’s Opticast forecast system utilises realtime observations from the Bureau of Meteorology, our client’s weather stations, Weatherzone’s own weather station network and from weather agencies across the globe for both improvements in accuracy and realtime adjustments of forecast in rapidly changing situations.

Weatherzone meteorologists also provide tailored forecasting services, television scripts, news stories and videos to meet your every need.

Lifestyle information for surf is sources from Australia’s most popular surf site, whilst snow reports are sourced from the major Australian ski resorts.

Observations, current conditions and climatological information

This information is sourced from the Bureau of Meteorology, Metservice NZ, the World Meteorological Organisation and the US National Weather Service. Weatherzone also has its own forecast model known as Opticast and its own Australia-wide lightning network. In some cases, Weatherzone applies formulae to the data in order to create additional fields for specific purposes. Examples of these are “wind chill”, “heat stress”, “growing degree days” and so on.

Weather observations are provided to clients with limited quality control.

Weather forecasts

Australian weather forecasts supplied by Weatherzone are sourced from Bureau of Meteorology forecasts or created by in-house models. Additional forecasts are provided by overseas providers including Metservice NZ, Customweather and the WMO.

The Bureau of Meteorology also provides marine forecasts, weather warnings and aviation forecasts.

Increasingly, Weatherzone is replacing Bureau of Meteorology forecasts with independent forecasts produced by in-house modelling and meteorologists.

Major city forecasts are here: Melbourne weather, Sydney weather, Brisbane weather, Perth weather, Adelaide weather

Long Range weather forecasts 14 days to 12 months

These forecasts are produced by Weatherzone meteorologists using raw information provided by international weather agencies.

These forecasts are produced using a combination of techniques, some in the public domain and others developed by Weatherzone. The result is a suite of long range forecasts that are considered to be the most accurate available for the Australian region.

Weather maps and computer generated forecast charts

Weatherzone provides a large range of weather forecast guidance heavily based on computer models. These computer models are run by ECMWF, US National Weather Service and the Bureau of Meteorology. In addition, Weatherzone runs computer models in-house to generate additional forecast guidance for specific applications.

In most cases these computer generated forecast charts are provided with little or no quality control and should only be used in conjunction with other meteorological guidance.

Regardless of the organisation running the model, all computer forecast models for the Australian region are run using source files collected by the Bureau of Meteorology.
