Current conditions and forecasts for farm fields, sourced from the Agronomy module.

When to Use This

What this skill handles: Current weather conditions, forecasts, growing degree days (GDD), spray condition evaluation, and historical weather data for farm fields.

Trigger phrases: "what's the weather", "can we spray", "GDD for field X", "forecast", "will it rain this week?", "temperature and wind right now", "field conditions?"

What this does NOT handle: Field observations about weather damage like hail, flooding, or frost injury (use farmos-observations with weather_damage type -- that logs the damage for tracking). This skill tells you what the weather IS; observations logs what the weather DID.

Minimum viable input: "Weather" or a field reference. If no field is specified, any nearby field ID works since all 69 fields are in central Indiana.

API Base

Endpoints

Health Check

GET /api/weather/health

Returns: Weather service health status.

Current Weather

GET /api/weather/field/{field_id}/current

Returns: Current conditions for a specific field (temperature, precipitation, wind).

Forecast

GET /api/weather/field/{field_id}/forecast?days=7

Returns: Daily and hourly forecast data (up to 14 days).

Historical

GET /api/weather/field/{field_id}/historical?days=30

Returns: Historical weather records for a field.

Growing Degree Days

GET /api/weather/field/{field_id}/gdd?startDate=YYYY-MM-DD&endDate=YYYY-MM-DD&baseTemp=10

Returns: GDD accumulation for a field over a date range.

Spray Conditions

GET /api/weather/field/{field_id}/spray-conditions

Returns: Spray condition evaluation (wind, rain probability, temperature checks).

Weather by Coordinates

GET /api/weather/coordinates?latitude={lat}&longitude={lon}&type=current

Returns: Weather by coordinates (no field ID required). Use type=forecast for forecast data.

Integration Dashboard

GET /api/integration/dashboard

Returns: Agronomy summary including weather data if available.

Data Completeness

• The /api/integration/dashboard returns agronomy summary data — use it for a quick overview only, not as the primary weather source.
• If a weather endpoint fails or returns empty, say so: "The weather service isn't responding right now." Don't guess the weather.
• For GDD queries, always include the date range in your response so the user knows the scope: "GDD from April 1 to today: 1,142."

Cross-Module Context

When answering weather questions, think about what else on the farm is affected:

Weather → Tasks:

• Before answering "can we spray?" or "should we get in the field?", check farmos-tasks for what's on the board. Connect the forecast to specific scheduled work: "Rain Thursday through Saturday — if you're planning to spray field 14, today's your window."
• When reporting the forecast, flag weather-sensitive tasks that conflict: "You've got 3 spray tasks this week but wind picks up Wednesday. Today and tomorrow are your best shot."
• GDD milestones trigger agronomic actions. When GDD data crosses key thresholds (V6 ~450 GDD, VT ~1,100 GDD, R1 ~1,400 GDD for corn), connect to tasks: "Field 12 just hit 1,100 GDD — that's your V6 marker. Side-dress window is now. Want me to create a task?"

Weather → Observations:

• After extended rain + warm temps, flag disease pressure: "We've had 3 days of rain and highs in the 80s — conditions are ripe for gray leaf spot and tar spot. Worth scouting the corn this week."
• After frost or severe weather, suggest damage checks: "First frost was last night. Might be worth checking the late-planted fields for damage."
• Connect recent weather to existing observation patterns: if there are recent disease observations, note the weather connection.

Weather → Equipment:

• If rain is coming and there are field operations scheduled, note the equipment implication: "Rain starts Thursday — anything that needs to be in the field should get there before then."

Query farmos-tasks and farmos-observations alongside weather for any field operation question. You don't need to cross-reference on every simple "what's the temperature?" question — use judgment. Cross-reference when the weather materially affects the plan.

Units — Already Imperial, Display Directly

The weather API returns all values in US imperial units. Display them as-is — no conversion needed.

API field	Unit	Example display
temperature_max / temperature_min	°F	"high of 55°F"
precipitation_sum	inches	"about a quarter inch of rain"
wind_speed_10m_max / wind_gusts_10m_max	mph	"winds up to 21 mph"

Do not convert, do not relabel. 0.25 means 0.25 inches. 55 means 55°F. 16 means 16 mph.

Date Handling — Anchor to Today

The API returns dates as YYYY-MM-DD strings starting from today. The first entry is today, not tomorrow.

• Use your system date to label each day correctly: "Today (Feb 28)", "Tomorrow (Mar 1)", "Wednesday (Mar 2)"
• Do not assume the first forecast entry is tomorrow — it is today
• If you're unsure of today's date, say so rather than guess

Usage Notes

• Farm is located in central Indiana. If specific field weather isn't available, general local weather is fine.
• Spray conditions matter: wind speed under 10mph, no rain in forecast for 24hrs, temperature ranges.
• "Can we spray?" is a common question -- check wind, rain probability, and temperature via the spray-conditions endpoint.
• Field IDs are integers -- 69 fields across the operation. Most weather queries can use any nearby field ID since they are all in the same area.
• For coordinates-based queries without a field ID, use the /coordinates endpoint with the farm's approximate location (latitude ~40.25, longitude ~-85.67).
