How to Read Weather Forecasts
Understanding weather forecasts helps you plan your day, travel, and outdoor activities. This guide explains the key elements you'll find on any weather report, including NearWeather.
Temperature
Temperature tells you how warm or cold the air is. On NearWeather, you can toggle between Celsius (°C) and Fahrenheit (°F). The "feels like" temperature accounts for wind chill and humidity, often giving a more practical sense of comfort.
Humidity
Humidity is the amount of moisture in the air, shown as a percentage. Levels below 30% feel dry, while above 70% feels muggy. High humidity makes warm temperatures feel hotter and can signal incoming rain.
Wind Speed & Direction
Wind speed is measured in km/h or mph. Light winds (under 15 km/h) barely rustle leaves. Strong winds (over 50 km/h) can affect driving and outdoor activities. Wind direction indicates where the wind blows from — a "north wind" blows from north to south.
Atmospheric Pressure
Pressure is measured in hectopascals (hPa) or millibars. Standard pressure is ~1013 hPa. Rising pressure generally means improving weather, while falling pressure often signals storms or rain approaching.
Precipitation Probability
Shown as a percentage, this indicates the likelihood of rain or snow in a given period. A 40% chance means that, statistically, 4 out of 10 similar weather situations produced precipitation.
UV Index
The UV Index measures the strength of ultraviolet radiation from the sun:
- 0-2 (Low): Minimal risk. No protection needed for most people.
- 3-5 (Moderate): Wear sunscreen and sunglasses.
- 6-7 (High): Reduce sun exposure between 10am-4pm.
- 8-10 (Very High): Take extra precautions. Burns can occur quickly.
- 11+ (Extreme): Avoid outdoor exposure when possible.
Weather Icons & Conditions
Common weather conditions you'll encounter on NearWeather:
- Clear sky: No clouds, full sunshine
- Few clouds / Scattered clouds: Partly sunny with some cloud cover
- Overcast: Heavy cloud cover blocking most sunlight
- Drizzle / Rain / Heavy rain: Increasing intensity of rainfall
- Thunderstorm: Rain accompanied by lightning and thunder
- Snow / Sleet: Frozen precipitation
- Mist / Fog / Haze: Reduced visibility conditions
5-Day vs Hourly Forecasts
Hourly forecasts are most accurate for the next 12-24 hours. The 5-day forecast gives a broader trend but becomes less precise after day 3. Use hourly data for immediate planning and the 5-day view for trip planning.
Tips for Using Weather Data
- Check the "feels like" temperature before choosing what to wear
- Look at wind speed if planning cycling, sailing, or flying
- Monitor pressure trends over 24 hours for better storm prediction
- Combine humidity + temperature to assess comfort levels
- For critical decisions, always cross-reference with your local meteorological authority
