Good to Know
- Layer your clothing regardless of season—even in summer, evenings require jackets; winter demands thermal underwear, polar windbreakers, and insulated coats

- Waterproof jackets and rain gear are essential for autumn, spring, and winter
- Summer (December–February) has the longest daylight hours, starting around 6 AM and extending to nearly 10 PM, ideal for extended outdoor activities
- Winter daylight is short (9 AM–7 PM), but ski season (June–August) aligns with Southern Hemisphere winter school holidays, making accommodation book out months in advance
- The wettest months are May–June; the driest are January–February
- If skiing, July and August offer optimal snow conditions; book well ahead during these months
