### HTTP Session Customization with requests_cache and retry

Source: https://deepwiki.com/open-meteo/python-requests/2.1-installation-and-basic-usage

Configures a custom HTTP session with SQLite caching and retry logic, then passes it to the openmeteo_requests client. Use this to enable caching, retries, and authentication for API calls.

```python
import openmeteo_requests
import requests_cache
from retry_requests import retry
 
# Setup caching with SQLite backend
cache_session = requests_cache.CachedSession('.cache', expire_after=-1)
 
# Add retry mechanism for resilient API calls
retry_session = retry(cache_session, retries=5, backoff_factor=0.2)
 
# Initialize client with custom session
om = openmeteo_requests.Client(session=retry_session)
```

--------------------------------

### Synchronous Client Usage with openmeteo_requests.Client

Source: https://deepwiki.com/open-meteo/python-requests/2.1-installation-and-basic-usage

Initializes a synchronous openmeteo_requests.Client and sends a blocking request to the Open-Meteo forecast API. The params dictionary defines latitude, longitude, hourly and current variables. The response is a list of WeatherApiResponse objects; the first element is accessed as response.

```python
import openmeteo_requests
from openmeteo_sdk.Variable import Variable
 
# Initialize synchronous client
om = openmeteo_requests.Client()
 
# Define request parameters
params = {
    "latitude": 52.54,
    "longitude": 13.41,
    "hourly": ["temperature_2m", "precipitation", "wind_speed_10m"],
    "current": ["temperature_2m", "relative_humidity_2m"]
}
 
# Make API request
responses = om.weather_api("https://api.open-meteo.com/v1/forecast", params=params)
response = responses[0]
```

### Asynchronous Client Usage with openmeteo_requests.AsyncClient

Source: https://deepwiki.com/open-meteo/python-requests/2.1-installation-and-basic-usage

Uses openmeteo_requests.AsyncClient for non-blocking requests. The async function fetch_weather_data awaits the weather_api call and returns the first response. asyncio.run executes the coroutine, suitable for concurrent data processing.

```python
import openmeteo_requests
import asyncio
 
async def fetch_weather_data():
    # Initialize asynchronous client
    om = openmeteo_requests.AsyncClient()
    
    # Same parameter structure as synchronous client
    params = {
        "latitude": 52.54,
        "longitude": 13.41,
        "hourly": ["temperature_2m", "precipitation", "wind_speed_10m"],
        "current": ["temperature_2m", "relative_humidity_2m"]
    }
    
    # Await API response
    responses = await om.weather_api("https://api.open-meteo.com/v1/forecast", params=params)
    return responses[0]
 
# Execute async function
response = asyncio.run(fetch_weather_data())
```

```python
# Access current weather data
current = response.Current()
current_variables = list(map(lambda i: current.Variables(i), range(0, current.VariablesLength())))
 
# Filter specific variables using openmeteo-sdk Variable enum
current_temperature_2m = next(filter(
    lambda x: x.Variable() == Variable.temperature and x.Altitude() == 2, 
    current_variables
))
current_relative_humidity_2m = next(filter(
    lambda x: x.Variable() == Variable.relative_humidity and x.Altitude() == 2, 
    current_variables
))
 
# Extract values
print(f"Current temperature: {current_temperature_2m.Value()}")
print(f"Current humidity: {current_relative_humidity_2m.Value()}")
```

Extract hourly data as NumPy arrays using zero-copy conversion via ValuesAsNumpy(). Filter variables by Variable enum and altitude, and generate the time range from the hourly structure's Time, TimeEnd, and Interval.

```python
import numpy as np
 
# Access hourly data structure
hourly = response.Hourly()
hourly_time = range(hourly.Time(), hourly.TimeEnd(), hourly.Interval())
hourly_variables = list(map(lambda i: hourly.Variables(i), range(0, hourly.VariablesLength())))
 
# Extract NumPy arrays using zero-copy conversion
hourly_temperature_2m = next(filter(
    lambda x: x.Variable() == Variable.temperature and x.Altitude() == 2, 
    hourly_variables
)).ValuesAsNumpy()
 
hourly_precipitation = next(filter(
    lambda x: x.Variable() == Variable.precipitation, 
    hourly_variables
)).ValuesAsNumpy()
 
hourly_wind_speed_10m = next(filter(
    lambda x: x.Variable() == Variable.wind_speed and x.Altitude() == 10, 
    hourly_variables
)).ValuesAsNumpy()
```

hourly_data = {
    "date": pd.date_range(
        start=pd.to_datetime(hourly.Time(), unit="s"),
        end=pd.to_datetime(hourly.TimeEnd(), unit="s"),
        freq=pd.Timedelta(seconds=hourly.Interval()),
        inclusive="left"
    )
}
 
# Add weather variables from NumPy arrays
hourly_data["temperature_2m"] = hourly_temperature_2m
hourly_data["precipitation"] = hourly_precipitation
hourly_data["wind_speed_10m"] = hourly_wind_speed_10m

### Create Polars DataFrame from FlatBuffers time data

Source: https://deepwiki.com/open-meteo/python-requests/2.1-installation-and-basic-usage

Creates a Polars DataFrame using pl.datetime_range with closed="left" and native datetime handling. Converts FlatBuffers timestamps to timezone-aware datetime objects before building the DataFrame.

```python
import polars as pl
from datetime import datetime, timedelta, timezone
 
# Convert FlatBuffers timestamps to datetime objects
start = datetime.fromtimestamp(hourly.Time(), timezone.utc)
end = datetime.fromtimestamp(hourly.TimeEnd(), timezone.utc)
freq = timedelta(seconds=hourly.Interval())
 
# Create Polars DataFrame with datetime range
hourly_dataframe_pl = pl.select(
    date=pl.datetime_range(start, end, freq, closed="left"),
    temperature_2m=hourly_temperature_2m,
    precipitation=hourly_precipitation,
    wind_speed_10m=hourly_wind_speed_10m
)
```

--------------------------------

### Create pandas DataFrame from time-series data
