The BOM Weather application, available through the Google Play Store, provides free access to radar imagery without advertisements. The app displays current radar coverage, severe weather warnings, and animated loops showing approximately 90 minutes of past rainfall alongside short-term future estimates.
Mobile users benefit from the same 1km resolution data available on the desktop platform, though screen size naturally limits the detail visible without zooming. The app supports offline access to previously viewed radar imagery, useful when monitoring conditions in areas with limited connectivity.
Understanding Radar Loops
Animated radar loops available for Regatta Point display precipitation movement over time, typically covering the most recent 90-minute observation period. These loops help users track storm direction and speed, valuable information for anyone planning outdoor activities or monitoring developing weather situations in western Tasmania.
Standard radar loops for Regatta Point display approximately 90 minutes of past precipitation data, with the animation cycling continuously. Users can pause, step through individual frames, or adjust playback speed depending on their analysis needs.
REG BOM Radar Status: Is It Operational?
The Bureau of Meteorology maintains continuous monitoring of all radar stations including Regatta Point. Status information is available through the official BoM radar page and the BOM Weather application, where users can verify current operational status before relying on the data for decision-making purposes.
Update Frequency and Data Refresh
The Regatta Point radar performs multiple 360-degree scans over approximately five-minute cycles, rotating at varying elevation angles to build comprehensive three-dimensional precipitation observations. This multi-scan approach captures data at different atmospheric heights, enabling more accurate rainfall estimates and improved detection of storm structure.
Processed imagery updates in real-time through BoM’s mosaic system, with the national viewer combining data from all stations into a seamless composite. The improved 1km grid resolution—upgraded from the previous 2km system—provides sharper definition of small-scale, intense rainfall events that might otherwise be averaged into surrounding pixels.
Monitoring Availability
No specific outages affecting Regatta Point were noted in available operational records. However, like all electronic monitoring systems, the radar may experience temporary service interruptions during severe weather events, scheduled maintenance periods, or due to technical issues.
Users requiring backup information during periods of suspected outage can consult the national mosaic viewer, which automatically adjusts coverage display based on real-time station availability. Neighboring Tasmanian radar stations provide overlapping coverage that may partially compensate for brief regional outages.
The BoM radar page displays individual station status indicators. If the Regatta Point station appears unavailable, consult the national mosaic for combined coverage or use the BOM Weather app to verify accessibility through alternative interfaces.
How to Interpret REG BOM Radar Images
Understanding the data displays available through the Regatta Point radar helps users extract meaningful information about current and developing weather conditions. The BoM viewer offers multiple display modes, each presenting different aspects of atmospheric conditions detected by the radar system.
Understanding Display Modes
Rain Rate (mm/h): This display mode estimates rainfall intensity in millimetres per hour. Warmer colours indicate heavier precipitation, with the scale typically ranging from light showers through to extreme rainfall events. Users monitoring for potential flooding or significant precipitation can focus on areas showing sustained high rain rates.
Reflectivity (dBZ): The default display mode measures the strength of radar signal returned from precipitation particles. Higher dBZ values indicate stronger echoes from larger water droplets or ice crystals. This measurement helps identify thunderstorm potential, with values above certain thresholds suggesting hail or intense convective activity. Users can switch between dBZ and rain rate views through the “More weather” settings menu.
Doppler Wind: This mode displays wind velocity data derived from the radar’s Doppler capability, showing the speed and direction of precipitation particles in motion. Useful for identifying wind shear, storm rotation potential, and the approach of cold fronts or wind shifts.
Reading Colour Intensity
Radar imagery uses a standardised colour palette where progression from greens through yellows, oranges, and reds indicates increasing precipitation intensity. Darker reds typically represent very heavy rainfall or large hail, while blues and light greens indicate lighter showers or drizzle.
It is important to note that radar signals can be affected by factors other than precipitation. The BoM’s updated processing engine removes clutter artifacts caused by mountain ranges, buildings, and other static objects that previously created false echo displays. The system now prioritises lowest available elevation observations for ground-level accuracy.
Radar imagery shows precipitation in the atmosphere, not necessarily surface rainfall. Some rainfall evaporates before reaching the ground (virga), and the radar beam may overshoot shallow precipitation at greater distances. Ground-based observations remain essential for confirming actual rainfall amounts.
How REG Compares to Other BOM Radars
Australia’s radar network encompasses stations across all states and territories, with each location optimised for specific regional monitoring needs. Comparing the Regatta Point radar to other stations highlights both common features and unique capabilities suited to Tasmania’s weather patterns.

Regional Strengths and Limitations
Regatta Point excels at detecting weather systems approaching Tasmania from the Southern Ocean, including cold fronts, cutoff lows, and west-coast rain events that are characteristic of the region’s climate. The radar’s placement captures orographic rainfall induced by the island’s mountainous terrain, providing valuable data for hydrographers and water resource managers.
Compared to capital city radars such as Sydney or Melbourne, the REG station serves a smaller population base but remains critical for maritime interests, fisheries, and western Tasmania communities. The absence of large urban interference means less ground clutter, though the rugged terrain can create some viewing shadows behind mountain ranges.
All radars in the BoM network—including Regatta Point—feed into the unified mosaic viewer, eliminating the need to navigate between individual station pages. This integration means users monitoring large-scale weather events can seamlessly pan from Tasmania to mainland Australia without changing interfaces or losing contextual awareness.

The REG Radar in Tasmania’s Weather Context
Tasmania’s climate is heavily influenced by its position in the Southern Ocean, with western regions experiencing some of the highest annual rainfall totals in Australia. Weather systems affecting this area typically approach from the west and southwest, bringing moisture-laden air masses that interact with the island’s mountainous terrain to produce significant orographic precipitation.
The Regatta Point radar provides essential monitoring capability for these moisture-laden systems. During active storm periods, the radar helps forecasters track the movement and intensity of cold fronts, cutoff lows, and atmospheric river events that can deliver substantial rainfall within short timeframes. Emergency management agencies rely on this data when assessing flash flood potential in western Tasmania’s river catchments.
Marine and coastal interests also benefit from the radar’s coverage. Commercial fishing vessels, aquaculture operations, and recreational boaters operating in the waters west of Tasmania use radar imagery to anticipate deteriorating conditions before venturing offshore. The combination of precipitation detection and Doppler wind capability provides a comprehensive picture of developing weather hazards.
Seasonal patterns in Tasmania include increased storm activity during the cooler months when frontal systems are most frequent. During these periods, the Regatta Point radar typically operates at heightened monitoring levels, with data refresh rates and alert thresholds adjusted to match the elevated risk environment. Understanding these seasonal patterns helps users anticipate periods when radar data may be particularly valuable for planning purposes.
