Quick Start

from agrivisor import OpenWeatherClient

# Initialize the client with your API key
client = OpenWeatherClient(api_key="your_api_key_here")

# Get current weather for Dublin, Ireland
weather = client.get_current_weather(lat=53.3498, lon=-6.2603)
print(f"Temperature: {weather.temperature}°C")
print(f"Humidity: {weather.humidity}%")
print(f"Weather: {weather.weather_description}")

API Reference

OpenWeatherClient

The main client class for interacting with OpenWeather APIs.

Initialization:

client = OpenWeatherClient(
    api_key: str,           # Required: Your OpenWeather API key
    units: str = "metric",   # Optional: "metric", "imperial", or "kelvin"
    language: str = "en"     # Optional: Language code for descriptions

Usage Examples

Current Weather

from agrivisor import OpenWeatherClient

client = OpenWeatherClient(api_key="your_api_key")

# Get current weather by coordinates
weather = client.get_current_weather(lat=53.3498, lon=-6.2603)

# Or get weather by city name
weather = client.get_current_weather(city_name="Dublin", country_code="IE")

print(f"Location: {weather.location_name}, {weather.country}")
print(f"Temperature: {weather.temperature}°C")
print(f"Feels like: {weather.feels_like}°C")
print(f"Humidity: {weather.humidity}%")
print(f"Pressure: {weather.pressure} hPa")
print(f"Wind Speed: {weather.wind_speed} m/s")
print(f"Weather: {weather.weather_main} - {weather.weather_description}")
print(f"Rain (1h): {weather.rain_1h} mm" if weather.rain_1h else "No rain")

# Get a simplified weather snapshot for game use
snapshot = client.get_weather_snapshot(lat=53.3498, lon=-6.2603)
# Returns: {'temp': 18.5, 'humidity': 70, 'rain': True, 'wind': 5.2, 'updatedAt': '...'}

# Check if it's raining
if client.is_raining(lat=53.3498, lon=-6.2603):
    print("It's raining!")

# Get a human-readable summary
summary = client.get_weather_summary(city_name="Dublin", country_code="IE")
print(summary)  # "Dublin, IE: 18.5°C, Partly Cloudy, Humidity: 70%, Wind: 5.2 m/s"

Hourly Forecast (4 days)

# Get hourly forecast by coordinates
forecasts = client.get_hourly_forecast(lat=53.3498, lon=-6.2603)

# Or by city name
forecasts = client.get_hourly_forecast(city_name="Dublin", country_code="IE", cnt=24)

# Get first 24 hours
for forecast in forecasts[:24]:
    print(f"{forecast.datetime}: {forecast.temperature}°C, {forecast.weather_description}")
    if forecast.rain_3h:
        print(f"  Rain: {forecast.rain_3h} mm")

Daily Forecast (16 days)

# Get daily forecast by coordinates
daily_forecasts = client.get_daily_forecast(lat=53.3498, lon=-6.2603, cnt=7)

# Or by city name
daily_forecasts = client.get_daily_forecast(city_name="Dublin", country_code="IE", cnt=7)

for forecast in daily_forecasts:
    print(f"{forecast.date}:")
    print(f"  High: {forecast.temp_max}°C, Low: {forecast.temp_min}°C")
    print(f"  Weather: {forecast.weather_description}")
    print(f"  Precipitation chance: {forecast.pop * 100}%")
    if forecast.rain:
        print(f"  Rain: {forecast.rain} mm")

Air Pollution

# Get air pollution data by coordinates
pollution = client.get_air_pollution(lat=53.3498, lon=-6.2603)

# Or by city name
pollution = client.get_air_pollution(city_name="Dublin", country_code="IE")

print(f"Air Quality Index: {pollution.aqi} ({pollution.aqi_description})")
print(f"PM2.5: {pollution.pm2_5} μg/m³")
print(f"PM10: {pollution.pm10} μg/m³")
print(f"Ozone (O3): {pollution.o3} μg/m³")
print(f"Carbon Monoxide (CO): {pollution.co} μg/m³")

Geocoding

# Convert city name to coordinates
results = client.geocode("Dublin", country_code="IE")
if results:
    location = results[0]
    print(f"Found: {location.name}, {location.country}")
    print(f"Coordinates: {location.lat}, {location.lon}")

# Reverse geocoding (coordinates to city name)
results = client.reverse_geocode(lat=53.3498, lon=-6.2603)
if results:
    print(f"Location: {results[0].name}, {results[0].country}")

Custom Units and Language

# Use Fahrenheit instead of Celsius
client = OpenWeatherClient(
    api_key="your_api_key",
    units="imperial"  # Options: "metric", "imperial", "kelvin"
)

# Use different language for weather descriptions
client = OpenWeatherClient(
    api_key="your_api_key",
    language="es"  # Spanish
)

Error Handling

The library provides specific exceptions for different error scenarios:

from agrivisor import (
    OpenWeatherClient,
    InvalidAPIKeyError,
    LocationNotFoundError,
    APIRequestError,
    OpenWeatherAPIError
)

client = OpenWeatherClient(api_key="your_api_key")

try:
    weather = client.get_current_weather(lat=53.3498, lon=-6.2603)
except InvalidAPIKeyError:
    print("Invalid API key. Please check your OpenWeather API key.")
except LocationNotFoundError:
    print("Location not found.")
except APIRequestError as e:
    print(f"Request failed: {e}")
except OpenWeatherAPIError as e:
    print(f"API error: {e}")

Data Models

All API responses are returned as Pydantic models with type validation:

• CurrentWeather - Current weather data
• HourlyForecast - Hourly forecast data
• DailyForecast - Daily forecast data
• AirPollution - Air pollution data
• GeocodingResult - Geocoding results

Integration with AgriQuest: Farm Guardian

This library is designed to work with the AgriQuest: Farm Guardian simulation system:

from agrivisor import OpenWeatherClient

# Initialize client with API key from environment or config
client = OpenWeatherClient(api_key=os.getenv("OPENWEATHER_API_KEY"))

# In your game turn logic:
def process_turn(farm_lat, farm_lon):
    # Get current weather
    current = client.get_current_weather(lat=farm_lat, lon=farm_lon)
    
    # Get forecast for next few days
    hourly = client.get_hourly_forecast(lat=farm_lat, lon=farm_lon, cnt=24)
    daily = client.get_daily_forecast(lat=farm_lat, lon=farm_lon, cnt=7)
    
    # Use weather data to influence game mechanics:
    # - Soil moisture changes based on rain
    # - Crop growth affected by temperature
    # - Forest health influenced by air quality
    # - Random events triggered by weather conditions
    
    return {
        "current_weather": current,
        "hourly_forecast": hourly,
        "daily_forecast": daily,
    }

API Endpoints Used

This library uses the following OpenWeather API endpoints:

• Current Weather: /data/2.5/weather
• Hourly Forecast (4 days): /data/2.5/forecast
• Daily Forecast (16 days): /data/3.0/onecall (with fallback to hourly aggregation)
• Air Pollution: /data/2.5/air_pollution
• Geocoding: /geo/1.0/direct and /geo/1.0/reverse
