Good and best months depend on more than temperature, rain and events. How they are chosen

Each activity on this page has its own good and best months, rated on twenty years of daily weather records. Which measures count, and how much, depends on the activity: humidity for exploring outdoors, wind for the beach, hiking and skiing, snow for skiing alone. Between them, the activities are rated on:

  • Daytime highs
  • Night-time lows
  • How warm it feels
  • Humidity
  • How much of the day is sunny
  • Hours of daylight
  • Monthly rainfall
  • How many days it rains
  • Days of heavy rain
  • Wind
  • Snowfall and days with snow
  • Major events, such as festivals

The chart shows the good and best months for exploring outdoors.

The event icon marks a month that an event lifts to good or best, such as a festival or a natural spectacle. Choose “Weather only” in the toolbar to rate the months on weather alone.

September–May
Good
June–August

Perth's dry Mediterranean climate suits walking and sightseeing almost all year: mild, sunny and largely dry from September to May, with the only real drawback being the warmth of January and February. The wet, cooler winter (June-August) brings the year's heaviest and most frequent rain, dropping those months to good rather than best.

November–April

Air is warm and dry enough for the beach from November to April, but the Indian Ocean never gets truly warm here (peaking near 24 C), keeping even the sunniest summer months to good rather than best. From May to October cooler air and a cold sea rule out a beach day, made worse by the year's heaviest rain in June-August.

Each figure is compared with the World Health Organization's guideline for a day's air, 15 µg/m³ or less, and with its interim targets above that. The words are ours: the WHO does not name its steps. The figures are modelled monthly averages, so single days can be well above them. The daily peak is the average of each day's highest hour, shaded on the same scale.
