bom.gov.au

BOM stands for the Bureau of Meteorology, Australia's official national weather agency, and its website at bom.gov.au is the primary public source for Australian weather forecasts, warnings, observations, and climate information. Use it when you need authoritative, government-issued weather data for anywhere in Australia — especially for severe weather warnings, flood information, and marine forecasts, where official sources matter more than third-party apps.

What BOM Is and What It Covers

The Bureau of Meteorology is the Australian government body responsible for providing the Australian community with weather and climate services. Its homepage describes the scope of what it publishes:

• Weather forecasts for Australian locations
• Severe weather warnings
• Observations (current conditions from monitoring stations)
• Flood information
• Marine and high seas forecasts
• Climate information

It also produces visual products including weather charts, satellite photos, radar pictures, and climate maps.

This range matters because it spans timescales — from what's happening right now (radar, observations) to what's coming in the next hours and days (forecasts, warnings) to long-term patterns (climate data).

How to Find a Forecast or Warning for Your Area

BOM organizes its services geographically, so the practical workflow is location-first:

1. Identify your location — the town, city, or region you need, or the marine/coastal area if you're on the water.
2. Go to the relevant forecast page for that location rather than reading a national summary, which won't reflect local conditions.
3. Check the warnings section in addition to the forecast. A forecast tells you expected conditions; a warning tells you that severe weather is occurring or imminent.
4. Cross-check with observations and radar if you want to see what's actually happening now versus what was predicted.

The key distinction: forecasts describe what's expected, warnings flag active or imminent threats. If you only read the forecast, you can miss a warning issued afterward.

Understanding the Different Product Types

BOM vs. Private Weather Apps

The main difference is source and authority. BOM is the official agency; many private apps either repackage BOM data or blend it with other models. For decisions where an official warning carries weight — evacuations, marine safety, flood response — going to the source avoids the lag and interpretation that can come with third-party apps.

If you use a private app for convenience, it's still worth checking BOM directly when conditions are severe, because that's where official warnings originate.

Common Points to Watch

• Warnings can be issued after you last checked — re-check during changing conditions rather than relying on a morning forecast.
• Location precision matters — a forecast for a nearby larger town may not match your exact area, especially for rainfall.
• Marine and land forecasts are separate — if you're on the water, use the marine and high seas products, not the land forecast.
• Different products serve different time horizons — radar and observations for now, forecasts for hours to days, climate maps for the long view.
