Peterborough is looking at about 74°F for 2026-08-15 – 2026-08-16 — here's how to use that forecast.
What's the weekend looking like in Peterborough?
Peterborough, Ontario
Weekend air in Peterborough sits near 74°F / 53°F, plus only light rain on the books (~0.10 in) — enough to decide whether the trip is on.
With highs near 74°F, Peterborough works as a food-and-wander weekend — patio time, a long lunch, then whatever the evening weather allows.
If the numbers still look good by Friday, lock the plan around 74°F — not a vague “nice weather somewhere.”
Things to do
Bottom line
Go if the outlook still matches what you want. Peterborough is the trip — not a shortlist to compare.
Keep planning
