Understand the Weather Around You
Learn how weather works, how forecasts are created, and how to understand the data behind every forecast.
1. What Is Weather?
Weather means the condition of the atmosphere at a particular place and time. It can change from hour to hour and day to day.
Short-term atmospheric conditions.
Long-term average weather patterns over many years.
2. Weather Data Explained
Temperature
The measure of how hot or cold the air is, typically shown in Celsius (°C) or Fahrenheit (°F).
Feels Like
How the temperature actually feels to your body when humidity and wind speed are factored in.
Humidity
The amount of water vapor in the air. High humidity can make heat feel much more uncomfortable.
Rain Probability
The percentage chance of measurable precipitation occurring during the forecasted time period.
Wind Speed
Measured in km/h or mph, it shows how fast the air is moving. Strong winds can impact safety.
Wind Direction
The direction the wind is blowing from (e.g., North, East, South, West).
Air Pressure
The weight of the atmosphere. Falling pressure usually indicates an approaching storm.
Cloud Cover
The percentage of the sky that is covered by clouds at any given time.
Visibility
How far you can see clearly. Fog, dust, and heavy rain can severely reduce visibility.
UV Index
A measure of ultraviolet radiation strength. Higher values mean faster skin damage.
3. How Weather Forecasts Work
Modern forecasts combine observations, mathematical models, and supercomputers.
Collect ground data.
Monitor clouds from space.
Detect precipitation size & speed.
Supercomputers run math formulas.
Meteorologists interpret the data.

4. Understanding a Forecast (Example)
- Temperature: 32°C (The actual air temperature)
- Feels Like: 35°C (It feels hotter due to humidity)
- Rain Probability: 70% (High chance of rain today)
- Humidity: 78% (The air holds a lot of moisture)
- Wind: 18 km/h (Moderate breeze)
- UV Index: 7 (High risk of sunburn, use protection)
- AQI: 92 (Air quality is acceptable/moderate)
5. Weather Symbols Guide
Clear skies
Sun and clouds mix
Overcast skies
Drizzle or showers
Intense downpour
Lightning and thunder
Low visibility
Freezing precipitation
Strong gusts
6. Air Quality and AQI
AQI (Air Quality Index) tells you how clean or polluted the air is. It measures pollutants like PM2.5, PM10, Ozone, and Nitrogen Dioxide.
7. Extreme Weather Facts
Extended periods of excessive heat.
Accompanied by lightning, strong winds.
Excessive water overflowing land.
Severe rotating storm system.
Rapid and dangerous drop in temperature.
Prolonged shortages in the water supply.
8. Weather Safety Checklists
During Extreme Heat
- Stay hydrated
- Avoid prolonged direct sunlight
- Check local warnings
During Thunderstorms
- Stay indoors when possible
- Avoid exposed locations
- Follow local safety guidance
During Heavy Rain
- Avoid flooded roads
- Follow local warnings
- Take care near fast-moving water
Poor Air Quality
- Check AQI levels
- Reduce prolonged outdoor exposure
- Follow local health guidance
