What it feels like

Rain changes how you move, and wind makes the same temperature feel much harsher.

When it tends to fit

  • If you’ll walk a lot and you’re sensitive to wind or rain, cooler/drier conditions tend to fit better.
  • For photo-and-walk trips, sunny days usually matter more than the exact temperature.
  • If you want to keep fatigue low (kids/family trips), avoiding peak midday heat helps.

When it may not fit

  • If you struggle with humid heat, some seasons can feel tiring even when the numbers look similar.
  • In rainier periods, “walking as planned” can be harder—tight itineraries may not fit well.
  • If you do many night outings, evening wind and chill can matter more than daytime highs.

What people usually wear

Not a single “correct outfit”—just common choices that cover most situations.

  • 🧩 Key idea: Ottawa has strong seasonal contrast. Winter is **cold + wind + snow/ice**, while summer comfort is often about **humidity (heat index)**.
  • ❄️ Winter (Dec–Feb): traction and staying dry can matter as much as insulation for comfort.
  • 🌦️ Spring (Mar–May): snowmelt means wet, slushy ground—layers and a waterproof option help.

Once you lock in a couple of constraints, the decision gets much easier.
