Wind & Site
Wind climate and current wind at a location: wind rose (direction and speed frequency) and latest wind conditions. Uses Open-Meteo (no API key). For detailed urban or building wind effects (pedestrian comfort, corner acceleration), use CFD tools; this skill provides the site wind data needed for context and input to such studies.
Dependencies
requestsnumpymatplotlib
Setup: OpenClaw does not install Python packages automatically. After installing this skill, run once: pip install -r requirements.txt (from the skill folder). If a script fails with ModuleNotFoundError, install the missing package.
Usage
1. Current or recent wind
Parameters: --lat, --lon, optional --days (0 = current from forecast; >0 = last N days from archive).
python3 scripts/wind_info.py --lat 31.23 --lon 121.47
python3 scripts/wind_info.py --lat 34.05 --lon -118.24 --days 7Output: latest wind speed (m/s) and direction (°), and period mean if multiple hours.
2. Wind rose
Parameters: --lat, --lon, --days (default 30), --output (default wind_rose.png).
python3 scripts/wind_rose.py --lat 31.23 --lon 121.47 --days 30 --output wind_rose.pngFetches hourly wind from Open-Meteo historical API and plots a wind rose (% of hours by direction and speed bins).
Sending images to Telegram
Used from the OpenClaw Telegram conversation. The wind rose is an image: run wind_rose.py with --output <path>.png. Then send that PNG to the user via the OpenClaw message/media tool. wind_info.py is text-only; use it for numbers and use the wind rose image for the visual.
OpenClaw allowed paths: The message tool can only send files from allowed directories. If you see "Local media path is not under an allowed directory", the image was saved outside them. Always use an allowed output path for the PNG:
~/.openclaw/media/(e.g.--output ~/.openclaw/media/wind_rose.png)~/.openclaw/agents/- The system temp dir (e.g.
/tmp/wind_rose.png)
Do not use the skill install directory (e.g. ~/.openclaw/skills/windsite/) as --output; that path is not allowed and sending will fail.
Agent behavior: When the user asks for wind at a site or a wind rose (with location or lat/lon), run the script directly with exec: use wind_info.py for current/recent wind text, and wind_rose.py --output <path>.png for the diagram, where <path> must be under an allowed directory (e.g. ~/.openclaw/media/wind_rose.png or /tmp/wind_rose.png); then send the wind rose PNG and summarize the numbers. Do not ask for confirmation; execute and return the image and data.
Urban wind effect
This skill does not run CFD or pedestrian wind simulation. It provides:
- Wind rose and wind speed/direction for the site, so you can see prevailing wind and strength.
- Use that data as input to CFD or specialist tools (e.g. SimScale, OpenFOAM, or wind-tunnel studies) for building/urban wind effects and comfort.
Examples
User: "What's the wind like at this site?" Action: Run wind_info.py for the site lat/lon; return speed, direction, and brief interpretation.
User: "Give me a wind rose for Shanghai for the last 30 days." Action: Run wind_rose.py --lat 31.23 --lon 121.47 --days 30 --output ~/.openclaw/media/wind_rose.png (or /tmp/wind_rose.png); send that file and return a short summary.
User: "I need to assess urban wind around a new tower." Action: Run wind_rose and wind_info for the site; explain that for building/urban effects they should use CFD or wind-tunnel studies, with this data as climate input.
