Ottawa Weather in October

October feels like autumn

Ottawa turns cool and changeable in October. Afternoons reach around 14°C, but evenings can feel chilly, with lows near 4°C. Rain falls on 14 days, and cloudy skies are common, so outdoor plans may need to bend.

You'll still find good days for walking Parliament Hill, exploring ByWard Market or following the Rideau Canal paths. For colour, head across the river to Gatineau Park. Long hikes are less appealing on wet, cold days, and a canal-side picnic may feel damp rather than relaxing.

Colours and Thanksgiving

Fall colour draws visitors to Gatineau Park, especially around the parkways and lookout points. Canadian Thanksgiving also falls in October. It's a family holiday, so some shops and services may close or keep shorter hours that day.

If you hate crowds, visit the park on a weekday rather than a sunny weekend. Travelling with kids? The Canadian Museum of Nature is a handy rainy-day stop, with indoor exhibits close to downtown.

A quieter city break

October is usually calmer than Ottawa's busy summer months, when festivals and outdoor events bring more visitors. Hotel prices often ease after summer, though Thanksgiving weekends and peak fall-colour days can still be busy. May and September are stronger choices for warmer sightseeing weather.

For a practical local tip, check Gatineau Park's official fall-colour updates before crossing the river. Colour changes across the park, and a sunny view from the Champlain Lookout can be worth the trip. If rain sets in, switch to the National Gallery of Canada, then warm up with a bowl of French onion soup in ByWard Market.
