# FarmOS Weather

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

http://100.102.77.110:8012

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

1. **The `/api/integration/dashboard` returns agronomy summary data** — use it for a quick overview only, not as the primary weather source.

2. **If a weather endpoint fails or returns empty**, say so: "The weather service isn't responding right now." Don't guess the weather.

3. **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:**

**Weather → Observations:**

**Weather → Equipment:**

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.
