March Weather in Kingston
Is March Right for You?
Advantages
- Pleasant shoulder season temperatures - highs around 87°F (30.6°C) are warm without the oppressive heat you'll get in summer months, making it actually comfortable to walk around midday unlike July or August
- Lower accommodation prices compared to peak winter season - you're looking at roughly 20-30% savings on hotels since spring break crowds have cleared out and summer vacation hasn't started yet
- Minimal rainfall with only 2.0 inches (51 mm) spread across 10 days means brief afternoon showers rather than day-long downpours - most rain happens between 2-4pm and clears within 30 minutes
- University rowing season on Lake Ontario brings energy to the waterfront with regattas most weekends - locals actually come out for these events and the lakefront patios start opening up for the season
Considerations
- Unpredictable weather swings are common in March - you might get a gorgeous 75°F (24°C) day followed by a chilly 50°F (10°C) morning, so you'll need to pack layers even though averages look mild
- Lake Ontario winds can make it feel 10-15°F (5-8°C) colder than the actual temperature, especially near the waterfront where most attractions are located - that 70% humidity cuts right through light jackets
- Some outdoor seasonal attractions don't fully open until April, and waterfront vendors are still operating on reduced spring hours rather than full summer schedules
Best Activities in March
Fort Henry Living History Tours
March is when Fort Henry transitions from winter programming to spring season, meaning smaller tour groups before the summer rush but with most exhibits already open. The 70% humidity is actually perfect for the stone fort - not the bone-dry cold of winter that makes exploring uncomfortable. You'll get the full military demonstration experience without fighting through July's tour bus crowds. The variable weather adds atmosphere to the fortifications honestly.
Thousand Islands Boat Tours
Early season boat tours start running in March when operators begin testing routes and ice conditions allow. You'll see the islands without the peak season crowds, and the cool temperatures around 69-87°F (20.6-30.6°C) mean comfortable sightseeing from covered boat areas. The 10 rainy days spread throughout the month rarely disrupt morning departures. Wildlife is more active in spring migration season - you'll spot birds that summer visitors miss entirely.
Downtown Kingston Food Walking Tours
March weather is ideal for walking tours - warm enough at 87°F (30.6°C) highs that you won't freeze, cool enough that you're not sweating through a 3-hour food crawl. The 70% humidity is noticeable but not oppressive like summer months. Local restaurants are introducing spring menus with maple syrup season ingredients, and you'll hit the sweet spot before tourist season when restaurants get slammed. The variable conditions mean you'll want tours that include indoor market stops.
Lake Ontario Waterfront Cycling Routes
The K&P Trail and waterfront paths are perfect in March - no summer heat, minimal crowds, and the 2.0 inches (51 mm) of rain doesn't create the muddy conditions you'd see in November. Morning rides from 9-11am avoid both the afternoon showers and the lake winds that pick up after 3pm. You'll cover 15-25 km (9.3-15.5 miles) comfortably in these temperatures. The variable weather means dramatic cloud formations over the lake that photographers actually seek out.
Rideau Canal Historic Sites Tours
March is when the canal transitions from winter ice to spring operations, and you'll catch unique seasonal views that summer visitors never see. The UNESCO World Heritage sites along the canal are accessible without peak season lineups, and the 69-87°F (20.6-30.6°C) range is perfect for the mix of outdoor walking and indoor museum time. The 10 rainy days actually work in your favor - museum staff have more time for questions during quieter wet afternoons.
Queen's University Campus and Limestone Architecture Walking Tours
March means the university is in session so you'll see actual campus life rather than empty summer buildings. The historic limestone architecture looks particularly striking in the variable March light, and the 70% humidity brings out the stone colors in ways dry summer air doesn't. Students are around for authentic campus atmosphere, and the moderate temperatures make the 2-3 km (1.2-1.9 mile) walking routes comfortable. Rain rarely lasts long enough to disrupt a 90-minute tour.
March Events & Festivals
Kingston Canadian Film Festival
This annual festival typically runs in early to mid-March and showcases Canadian independent films across multiple downtown venues. It's a genuine local event rather than a tourist attraction, which means you'll experience Kingston's actual arts community. Indoor venues make it perfect for those variable weather days, and evening screenings let you avoid afternoon rain windows entirely.
St. Patrick's Day Celebrations
Kingston has a substantial Irish heritage community and the March 17th celebrations are legitimately local rather than manufactured tourist events. The downtown pubs and Princess Street area host live music, and the moderate March temperatures mean you can actually enjoy the outdoor portions without freezing. Expect authentic Irish music sessions rather than just green beer promotions.
