Weather in Ottawa

The best time to visit Ottawa is between April and May, when temperatures can rise to 19°C (66°F). This time of year also coincides with some of the capital's key events, including the Tulip Festival. Summer is the most popular time for a visit, as it's the warmest time of year, with temperatures around 26°C (79°F) but it's also the most expensive. If you like ice-skating and festivals, go in the winter but wrap up warm and with several layers to keep the cold at bay. Temperatures can plummet to around -10°C (14°F).

We update the weather data for from our weather partner every four hours. The time the last update was received is detailed here.
Actual Forecast Location: We have 830+ weather locations on the worldtravelguide.net website. Where no exact location is available we have used the nearest appropriate forecast point.
Symbols indicate the predominant weather for the day in question, calculated based on a weighting of different types of weather. So if a day is forecast to be sunny with the possibility of a brief shower, then we will see a sunny or partly cloudy symbol rather than a rain cloud.
The maximum temperature is the highest temperature forecast between dawn and dusk, and the minimum temperature is the lowest temperature expected from dusk on the day in question to dawn the next day. The temperature is in °C, or Celsius.
Wind speed and direction are the conditions expected at midday. Wind direction is based on a 16 point compass. W, SW, SSW, etc. The wind direction states where the wind originates. Wind speed is listed in MPH or miles per hour.
Humidity levels indicates how much water vapour the air contains compared to the maximum it could contain at that temperature. As a general guide:
  • 0 to 30 is very low
  • 31 to 50 is low
  • 51 to 70 is moderate to low
  • 71 to 80 is moderate
  • 81 to 90 is moderate to high
  • 91 to 100 is high
Pressure is measured in millibars (mb)
Visibility based on whether the human eye can see the following distances:
  • Very poor - less than 1km
  • Poor - between 1km and 4km
  • Moderate - between 4km and 10km
  • Good - between 10km and 20km
