Meteogram Help

What is Meteogram?

Meteogram images show a summary of ACCESS and/or GFS forecasts over the next ten days (Day 1, Days 1-3, Days 3-5 and Days 5-10) for particular locations. The meteograms (time-series graphs) present detailed cloud information or a summary comparison of the two models. The table displays hourly (3-hourly or 6-hourly) values of the temperature, rainfall, wind, pressure, humidity, fog and total, low, middle and high cloud cover.

What is Forecast?

Official Forecast for the selected location from the Bureau of Meteorology.

Switching between Map, Meteogram and Satellite

To switch between Map, Meteogram or Satellite, swipe the website top banner from left or right, or right to left. If you change your map or satellite region and then select Meteogram the location will be reset to the capital city associated with the selected region. If you change your meteogram location and then select Map or Satellite the region will automatically revert to the region associated with the selected meteogram location.

Displaying Cloud Camera

To display the nearest cloud camera to the current meteogram location select the CLOUDCAM button on the Dark Sky, Meteogram, Radar or Satellite page. The cloud camera image(s) will be displayed with the cloud camera name, display/hide overlay and astronomy/storm mode toggles, and a list of other cloud cameras. More than one camera image may be displayed by sliding the scroll bar or swiping the screen. Cardinal points will be plotted on top of the image. If Display Overlay is selected, icons for other cloud cameras may be plotted on top of the camera images. In Astronomy Mode, only your selected cloud cameras will be plotted as icons on the camera image, map, radar and satellite pages. In Storm Mode, all cloud cameras will be plotted as icons on the camera image, map, radar and satellite pages.
