What Weather Conditions Affect Fall Colours?

Introduction

Every autumn is different. Some years the colours are vivid, other years muted. Weather is the main reason.

Weather Factors

• Warm sunny days with cool nights = the most brilliant colours.
• Too much rain = dull leaves.
• Early frost = leaves fall quickly.
• Drought = muted or early colour change.

Insider Tip

Even if the weather dulls one region, others may still shine. Hamilton valleys hold leaves longer; Toronto trails last into late October. Flexibility ensures you catch the best show available.
