Get Hourly Forecasts in Detail

Need precise planning? The `get_hourly_forecast` tool returns temperature, precipitation, wind, and humidity predictions for every single hour. This level of detail is perfect when timing matters. It's crucial for agents managing time-sensitive activities, like outdoor construction or event staging. You get granular data you can trust.

MCP Server: Verify Recent Weather Events

To check what happened right before the agent runs, use `get_recent_history`. It returns actual observed conditions—temperature, wind, precipitation—for the last 24 hours. This verifies recent events. Pair this with `get_route_weather` to give your user confidence in logistics planning. The agent checks both the route and what actually happened recently.

Forecasting for Short-Term Needs

The `get_forecast` tool gives you a wide view of up to 14 days, including wind, humidity, and precipitation probability. It's the go-to function for standard long-term planning. If your agent needs just general preparation advice, `get_daily_forecast` handles weekly plans efficiently.
