Autumn Weather Guide — What Changes and Where

What Defines Autumn?

Autumn (September-November in the North, March-May in the South) is the cooling transition from summer to winter. Days shorten noticeably, temperatures drop, and many regions experience their most photogenic weather.

Autumn by Region

North America

New England foliage peaks mid-October. Hurricane season continues through November. Temperatures drop from 25°C in September to 5°C by late November in northern states.

Europe

Mild September gives way to cool, damp October-November. Mediterranean stays pleasant into October. Northern Europe gets dark quickly.

East Asia

Typhoon season winds down. Japan's koyo (autumn colours) peaks in November. Clear, crisp days ideal for travel.

Tropics

Monsoon seasons end in many regions. October-November is a transition to dry season in Southeast Asia and India.

Why Autumn Travel Is Underrated

Autumn Weather Challenges

• Shortening days: Plan outdoor activities earlier
• Variable weather: Layers are essential; rain jackets earn their keep
• Fog: Morning fog is common in valleys and near water
• Early frost: Can catch gardeners off guard; protect tender plants

What to Pack

A medium-weight jacket, a few long-sleeve layers, and a waterproof shell cover most autumn scenarios. Include a warm hat and scarf for evenings.
