🌤 5-Day Weather Forecast

The app now fetches and displays a 5-day weather forecast, including:

• Daily temperature trends
• Humidity levels
• Weather conditions

Example API Call for Forecast Data

BASE_FORECAST_URL = "https://api.openweathermap.org/data/2.5/forecast"
def get_5day_forecast(city):
    params = {"q": city, "appid": API_KEY, "units": "metric"}
    response = requests.get(BASE_FORECAST_URL, params=params)
    if response.status_code == 200:
        return response.json()
    return {"error": "City not found!"}

---

📈 Graphical Weather Trends

The app now includes visual graphs to display:

• Temperature trends over 5 days
• Humidity variations

Example Graph Using Matplotlib

import matplotlib.pyplot as plt
def plot_weather_trends(forecast_data):
    dates = [item['dt_txt'] for item in forecast_data['list'][:5]]
    temps = [item['main']['temp'] for item in forecast_data['list'][:5]]
    plt.plot(dates, temps, marker='o', linestyle='-', color='b')
    plt.xlabel('Date')
    plt.ylabel('Temperature (°C)')
    plt.title('5-Day Temperature Trend')
    plt.xticks(rotation=45)
    plt.show()
