A simple API key example package

📦 Weather Data Client

This package includes a function to fetch and preprocess historical weather data from Weatherunderground.com.

🔧 Setup

1. Create a .env file with your API key:

   echo "API_KEY=your_actual_api_key_here" > .env
   

2. Install the package:

   pip install .
   

3. (Optional) Install dev dependencies:

   pip install .[dev]

📘 Usage

import getweatherunderground.client as gwu
import os
os.environ["API_KEY"] = "ADD_API_KEY"

df = gwu.get_weather_data(
    weather_station="RJAA",
    country_code="JP",
    startDate="20190201",
    endDate="20190301",
    timezone="US/Pacific"
)
print(df.head())

Dataframe Sample

Feature	Type	Example
Time	datetime	2019-01-31 00:00:00
tempf	float	32.0
dewPt	int	32
rh	int	100
wdir_cardinal	string	NNW
wspd	float	9.0
gust	int	0
pressure	float	29.47
precip	float	0.0
wx_phrase	string	Light Snow Shower

Parameters

Parameters can be obtained from https://www.wunderground.com/. For a desired location follow these steps.

1. Search locations in the upper right. For example Manila, Philippines.
2. Click the history tab and identify the weather station which would be the last parameter in the URL:

   https://www.wunderground.com/history/daily/ph/manila/RPLL
   

   Here it would be RPLL.
3. The country code would be the third to the last parameter: PH
4. Timezone would be what you want the data to be encoded in, for Manila it would be 'Asia/Manila'
5. Start and end dates must be strings in the form of YYYYMMDD. The minimum window should be 1 month. i.e., 20201001 to 20201101.

Thus the arguments you would use would be: df = get_weather_data(weather_station="RPLL", country_code="PH", startDate="20201001", endDate="20201101", timezone="Asia/Manila")

📊 Weather Feature Descriptions

Column	Description
Time	The timestamp of the weather observation, converted from GMT to your specified timezone. This is usually reported in hourly intervals and used as the index for the DataFrame.
tempf	Air temperature in degrees Fahrenheit at the time of observation.
dewPt	Dew point in degrees Fahrenheit – the temperature at which air becomes saturated and dew can form. Used to assess humidity.
rh	Relative Humidity in percentage (%). Indicates how much moisture is in the air compared to the maximum possible at that temperature.
wdir_cardinal	Wind direction as a cardinal compass point (e.g., "N", "NE", "W"). Reflects the direction from which the wind is blowing.
wspd	Wind speed in miles per hour (mph). Average wind speed during the observation window.
gust	Wind gust in mph. Peak wind speed recorded during the observation window. May be missing or zero if conditions were calm.
pressure	Atmospheric pressure in inches of mercury (inHg). Often used in weather forecasting (e.g., identifying high/low pressure systems).
precip	Total precipitation during the hour in inches (rain, snow water equivalent, etc.). May be "0.0" if no measurable precipitation occurred.
wx_phrase	Textual weather summary, e.g., "Partly Cloudy", "Rain Showers", "Snow", etc. Useful for quick human-readable interpretation of the weather conditions.
