When to go to Blue Mountains

Autumn and spring are ideal; winter brings crisp clear days and the chance of snow.

The upper mountains are much cooler than Sydney. Summers are warm with storms, winters are cold with frosts and occasional snow, and mist is common at any time.

Season by season

Spring (September–November)

Gardens in bloom, waterfalls flowing and pleasant walking weather. Leura’s gardens are at their best.

Summer (December–February)

Warm days, afternoon storms and the busiest weekends. Check bushfire ratings and track alerts.

Autumn (March–May)

Autumn leaves in the gardens of Leura and Mount Wilson, and stable weather for walking.

Winter (June–August)

Cold, clear days, cosy fires and the occasional snowfall. Fewer crowds midweek.
