Chance of precipitation represents how likely it is that rain (or other types of precipitation, such as sleet, snow, hail and drizzle) will fall from the sky at a certain time.
This number shows the air temperature for the time period. You can see the temperature in Celsius or Fahrenheit by using the dropdown menu.
Feels like temperature considers other factors, such as wind speed and humidity. This gives you a better idea of how the temperature will actually feel at the time.
Wind gust shows the highest wind speed that you should encounter at that time, as winds peak and lull.
Strong winds are shown in bold for speeds of 29 mph or more.
The arrow shows the direction the wind is blowing. The letters show the direction the wind is blowing from (on a standard 16-point compass).
The number represents the average wind speed expected at that time.
Visibility measures the distance at which an object can be clearly seen.
| VP (Very Poor) | Less than 1 km |
| P (Poor) | 1.1 km to 4 km |
| M (Medium) | 4.1 km to 10 km |
| G (Good) | 10.1 km to 20 km |
| VG (Very Good) | 20.1 km to 40 km |
| E (Excellent) | Greater than 40 km |
Humidity is the amount of water vapor in the air. If there is a lot of water vapour, the humidity will be high. The higher the percentage of humidity, the wetter it will feel outside.
