Temperature
2-metre air temperature. Available on all models.
Feels Like (ADFD only)
Apparent temperature accounting for wind chill and humidity. BoM official ADFD model only.
Wind Speed
10-metre sustained wind speed in km/h. Available on all models.
Wind Gust (ADFD only)
Maximum wind gust speed. BoM official ADFD model only.
Rainfall
Precipitation accumulation for each forecast period (typically 3 hours for NWP models, variable for ADFD).
Rainfall Totals
Running total precipitation from the start of the forecast run, cumulative rather than per-period.
Rainfall 50%/25%/10% (ADFD only)
Probabilistic rainfall for each forecast period from the BoM ADFD ensemble. The 50% figure is the median; 25% and 10% are higher-end amounts that are less likely but possible.
Daily Rain 50%/25%/10% (ADFD only)
The same probabilistic rainfall thresholds totalled over a full day rather than per forecast period. The 50% figure is the median daily total; 25% and 10% are progressively higher-end daily amounts.
Chance of Rain / Chance of ≥10mm/25mm/50mm (ADFD only)
Daily probability of rainfall exceeding the given threshold. Based on the BoM ADFD ensemble system.
Cloud Cover
Total cloud cover percentage across all levels. Not available on HGEFS or AIGFS.
ADFD: BoM Official (6km)
Australian Digital Forecast Database from the Bureau of Meteorology. The official Australian forecast, updated 4 times daily with 7-day forecasts. Includes probabilistic rainfall and apparent temperature that other models don't have. Best for Australian conditions.
ECMWF IFS (9km)
European Centre for Medium-Range Weather Forecasts Integrated Forecast System. Generally considered the most accurate global model. Updated every 6 hours with 10-day forecasts at 9km resolution.
ICON (13km)
German Weather Service (DWD) global model. Good performance across Australia. Runs every 6 hours with 7.5-day forecasts.
GFS (25km)
NOAA Global Forecast System. Widely-used operational model updated every 6 hours with 10-day forecasts.
ECMWF AIFS (25km)
ECMWF Artificial Intelligence Forecast System. Machine learning model trained on ERA5 reanalysis. Faster to run than IFS with competitive accuracy. Extended range to 15 days.
HGEFS: Ensemble Mean (25km)
NOAA Hybrid GEFS ensemble mean from 62 members. Shows the average of multiple model runs, smoother and more cautious than any single run, useful for identifying likely outcomes. 10-day range. Temperature, wind, and rainfall only.
AIGFS: AI-enhanced (25km)
NOAA AI-enhanced GFS. Uses machine learning to improve upon traditional GFS. Extended range to 16 days. Temperature, wind, and rainfall only.
Pressure
Lines of equal mean sea level pressure (MSLP) drawn at 4 hPa intervals. Isobars help identify high and low pressure systems, fronts, and troughs. Closely spaced isobars indicate strong pressure gradients and therefore stronger winds.
Isotherms
Lines of equal temperature drawn at 5°C intervals. Useful for identifying air mass boundaries, frontal zones, and temperature gradients across the forecast area.
Wind
Animated particles showing wind flow direction and relative speed. Particles move faster where winds are stronger. This visualisation helps identify wind patterns, convergence zones, and circulation features.
Warnings
Current BoM warning areas from the active warnings feed. These are live warning boundaries, not model forecast fields, so they do not change with the forecast timestamp.

NWP Weather Forecast
Numerical weather prediction models showing temperature, precipitation, wind and cloud cover. Use the timeline to step through forecast hours.
Parameters
