Open-Meteo Weather

Free weather API. No API key needed. Returns JSON.

Scripts

weather.sh — Raw JSON Forecast Data

scripts/weather.sh <latitude> <longitude> [current|hourly|daily] [days] [units]

• days: 1-16 (default 3)
• units: fahrenheit (default) or celsius
• current mode returns both current snapshot and daily forecast

scripts/weather.sh 37.75 -122.43 current 3 fahrenheit
scripts/weather.sh 37.75 -122.43 hourly 2 fahrenheit
scripts/weather.sh 37.75 -122.43 daily 7 fahrenheit

weather_strip.py — SVG Weather Strip Widget

Generates a Weather Strip-style interactive SVG visualization. Features:

• Smooth bezier curves for temperature and dew point
• Cloud cover area graph (semi-transparent, 0-100%)
• Rain amount bar graph (opaque light blue, 0-2 in/hr scale, shown when rain prob >50%)
• Rain probability line overlay
• UV index bar (yellow/orange/red at UV 3+)
• Sky gradient background (sky blue day → navy night, smooth sunrise/sunset transitions)
• Moon phase icon at sunset
• Fixed scrubber bar with scroll-to-read tooltip (shows all metrics)
• Multi-city support with time-range scheduling
• Fixed 0-110°F temperature scale
• 7-day daily forecast strip below hourly

# Single location
python3 scripts/weather_strip.py --lat 37.75 --lon -122.43 --days 7 \
  > /Users/dapkus/openclaw-apps/digest-app/static/weather-strip.html

# Standalone preview page
python3 scripts/weather_strip.py --lat 37.75 --lon -122.43 --days 7 \
  --output /Users/dapkus/openclaw-apps/digest-app/static/weather-strip-preview.html

# Multi-city with time ranges (for travel)
python3 scripts/weather_strip.py --schedule '[
  {"name":"SF","lat":37.75,"lon":-122.43,"ranges":[
    ["2026-03-01T00:00","2026-03-02T08:00"],
    ["2026-03-06T15:00","2026-03-07T23:00"]
  ]},
  {"name":"Palm Springs","lat":33.83,"lon":-116.55,"ranges":[
    ["2026-03-02T10:00","2026-03-06T13:00"]
  ]}
]' --days 7 > /Users/dapkus/openclaw-apps/digest-app/static/weather-strip.html

Schedule format: Each location has name, lat, lon, and either:

• ranges: list of ["start_iso", "end_iso"] pairs (hour-level precision, skips transit gaps)
• dates: list of "YYYY-MM-DD" strings (whole days, simpler)

Output: Without --output, prints embeddable <div> to stdout. With --output, writes a full standalone HTML page.

Digest Integration

The digest app reads static/weather-strip.html and includes it at the top of each digest page.

Regenerate daily as part of morning digest generation:

1. Generate weather strip → static/weather-strip.html
2. If travel scheduled, use --schedule with time ranges
3. Default: SF single-location

Common Coordinates

For other cities:

curl -sf "https://geocoding-api.open-meteo.com/v1/search?name=CityName&count=1" | jq '.results[0] | {name, latitude, longitude}'

WMO Weather Codes

Interpreting Results

• Parse JSON with jq
• precipitation_probability_max is the best "will it rain?" signal
• apparent_temperature = feels-like (wind chill + humidity)
• uv_index_max > 6 = recommend sunscreen
• Times are in the location's local timezone (auto-detected)

Presentation

Summarize weather conversationally. Lead with what matters: temperature, rain chance, anything unusual. Don't dump raw JSON.
