Ottawa is getting the May Long Weekend weather it deserves — mostly.

According to the latest forecast from CTV News Ottawa, the nation's capital can expect warm temperatures and plenty of sunshine to kick off the unofficial start of summer. A bit of rain is in the mix too, so if you're heading out of the city or planning a backyard gathering, it's worth keeping an eye on the sky.

Warm and Sunny to Start

The good news for outdoor enthusiasts: warm, sunny conditions are expected to dominate much of the long weekend. May Long is the traditional launch of camping season in Ontario and Quebec, and this year's forecast looks cooperative enough to get those first campfires of the season going.

For Ottawans who prefer to stay local, the weather sets up nicely for a trip to Gatineau Park, a stroll along the Rideau Canal, or a visit to one of the city's many farmers' markets and patios that are now in full swing.

A Bit of Rain in the Mix

Don't pack away the umbrella just yet. Some rain is expected at some point over the weekend, which is pretty typical for late May in the Ottawa Valley. The region sits in a zone where warm southern air clashes with cooler systems moving in from the north, making brief showers a regular feature this time of year.

The upside? A little rain in May means the tulips — still lingering from the Canadian Tulip Festival earlier this month — get one last drink before the summer heat fully takes hold.

Tips for Making the Most of the Weekend

Whether you're heading to a cottage, camping at Frontenac or Algonquin, or keeping it local in Ottawa, a few pointers:

  • Check conditions hourly — May weather in Ottawa can shift quickly, so real-time updates beat a static forecast
  • Layer up for evenings — warm afternoons can give way to cool nights, especially near the water
  • Book a patio with cover — many Ottawa restaurants along Elgin Street, Bank Street, and the ByWard Market have covered or heated outdoor spaces if showers roll in
  • Head to Gatineau Park early — it's one of the most popular long weekend destinations in the region, and parking fills up fast on sunny mornings

Ottawa's May Long Weekend Tradition

May Long — officially Victoria Day on Monday, May 19 — is one of Ottawa's most anticipated weekends of the year. It marks the point where the city truly shakes off winter mode: patios fill up, parks come alive, and the Ottawa River's kayaking and paddleboarding scene kicks into gear.

With warm weather and mostly good conditions in the forecast, this year's long weekend looks like a solid one to get outside and enjoy everything the capital has to offer.
