BOM weather integration for construction site records
Bureau of Meteorology (BOM) connector for retrieving weather observations, forecasts, and warnings. Used to add weather context to site diaries, assess weather impact on project delivery, and filter operational data by weather conditions.
Authentication: None - public API
System type: BOM_WEATHER
API reference: BOM Weather API
Supported resources
Section titled “Supported resources”| Resource | FETCH | LOOKUP |
|---|---|---|
location_search | ✓ Yes | — No |
observations | ✓ Yes | ✓ Yes |
daily_forecast | ✓ Yes | — No |
hourly_forecast | ✓ Yes | — No |
warnings | ✓ Yes | — No |
LOOKUP on observations retrieves current conditions by geohash (location code).
Registers this connector fills
Bureau of Meteorology keeps 1 register current in Civil Memory. Each name is the record you ask for, not the system it came from - ask for it in Studio or from your own AI client.
| Register | What it holds | Fields from Bureau of Meteorology |
|---|---|---|
Platform weatherplatform_weather | Current Bureau of Meteorology observations by region. | Fills all of 15 |
The full field list, requiredness and an example record for any register are on its published contract. Where more than one system fills a register, the register is the same shape either way.
Whether weather can ground an extension of time depends on the contract. The extension of time claims guide sets out what NZS 3910, TfNSW and Main Roads WA contracts allow.
Integration model
Section titled “Integration model”The adapter calls the Bureau of Meteorology’s public weather API. Location search resolves a place to a geohash, which the observation, forecast and warning resources then use.
Connection setup
Section titled “Connection setup”No credentials are required - the Bureau of Meteorology API is public and Demiton maintains the registration centrally.
Example queries via MCP
Section titled “Example queries via MCP”Once connected through the MCP server, you can ask Claude:
- “What were the weather conditions at the Cunningham Gap site last month?”
- “Were there any weather warnings active during the week of 10 March for postcode 4000?”
- “What is the forecast for our Morningside site this week?”
- “How many wet-weather days did we have at Burringbar in Q1?”
On Baseline, weather data can be correlated directly against site diary entries from Assignar - ask “Which days did weather delays get recorded in site diaries and what were the BOM conditions?”
Security
Section titled “Security”Access type: Read-only (public data)
The Bureau of Meteorology provides publicly available weather data. No credentials are required or stored. No private or organisation-specific data is involved.
