Best Time to Visit Perth
Perth is the sunniest capital city in Australia, averaging eight hours of sunshine daily. While you can visit year-round, March is the single best month to visit Perth. During March, the summer heat mellows into consistent mid-20s (Celsius), the Indian Ocean remains warm enough for swimming, and the city’s festival season is in full swing. You avoid the extreme 40°C heat spikes of February and the onset of winter rains in June. It is the ideal balance of outdoor weather, active events, and manageable crowd levels before the school holiday rushes.
Month by month breakdown
January
January is peak summer. Expect average highs of 31°C, though days frequently top 38°C. It is dry, bright, and windy in the afternoons due to the "Fremantle Doctor" sea breeze. Prices are at their highest because of Australian summer school holidays. Beaches like Cottesloe are packed. This is the best time for the Fringe World Festival, which brings pop-up venues and performance art to the CBD and Northbridge.
February
February is statistically the hottest month in Perth. Highs average 32°C, but heatwaves often push temperatures above 40°C for several days straight. Rainfall is almost non-existent. Crowds thin out slightly as schools return, but hotel prices remain firm. Use this month for the Perth Festival, a massive multi-arts celebration. If you struggle with high heat, stay near the coast or ensure your accommodation has high-quality air conditioning.
March
March offers the most reliable weather of the year. Temperatures cool to a comfortable average high of 29°C. The ocean is at its warmest after a summer of heating up. Flight prices begin to dip from their summer peaks. The Sculpture by the Sea exhibition takes over Cottesloe Beach this month, showcasing massive art installations against the sunset. It is the best time for outdoor dining and sunset drinks without the oppressive humidity of the tropics.
April
April marks the transition to autumn. Average highs drop to 26°C, and evenings become crisp. You will see fewer tourists, leading to better deals on boutique stays in Fremantle. This is the prime window for a day trip to Rottnest Island; the wind dies down, making the ferry crossing smoother and the turquoise bays perfect for snorkeling. Anzac Day (April 25) is a major public holiday with significant dawn services at Kings Park.
May
In May, the rains begin to arrive, though you will still see plenty of sun. Highs average 22°C. This is a shoulder season month where you can find significant discounts on luxury hotels. It is one of the best times for hikers to tackle sections of the Bibbulmun Track or walk through Kings Park as the vegetation begins to green up. The crowds are minimal, making it easy to get restaurant reservations without booking weeks in advance.
June
June is the start of winter and typically the wettest month. Temperatures range from 10°C at night to 19°C during the day. While it rains, it usually comes in short, heavy bursts rather than grey drizzle. Prices for accommodation are at their annual low. This is the best time for a day trip to the Swan Valley for wine tasting and heavy reds by a fireplace. Indoor galleries like the Art Gallery of WA are your best bet.
July
July is cool and brisk, with average highs of 18°C. You will need a jacket for the evenings when temperatures can drop to 8°C. It is the middle of the low season, so you can snag high-end CBD suites for a fraction of the summer price. For football fans, this is the height of the AFL season at Optus Stadium. Watching a West Coast Eagles or Fremantle Dockers home game is the quintessential local winter experience.
August
August remains cool with an average high of 19°C, but the frequency of rain starts to decrease. This is technically the end of winter, and the landscape is incredibly lush. Toward the end of the month, the famous Western Australian wildflowers begin to bloom in the northern suburbs and surrounding national parks. You can find excellent travel deals before the spring surge begins. It's a great month for whale watching as humpbacks migrate along the coast.
September
September is the start of spring and the peak of the wildflower season. Average highs reach 20°C. Kings Park hosts the Everlasting Kings Park Festival, featuring thousands of unique floral species. The city starts to buzz again, and prices begin to climb toward the mid-range. The weather can be unpredictable with occasional storms, but the clear days are some of the most beautiful of the year for photography.
October
October brings consistent spring weather with average highs of 23°C. It is the "sweet spot" before the summer heat arrives. The wind is low, and the city parks are at their greenest. This is the best time for the Perth Royal Show, a massive week-long agricultural event with rides and exhibitions. Prices are moderate, making it a popular time for domestic travelers. It is excellent weather for exploring the wineries of Margaret River, a three-hour drive south.
November
November is the start of beach season. Temperatures average 27°C, and the rain stops almost completely. International tourist numbers start to rise, and flight prices trend upward. The "Fremantle Doctor" breeze becomes a daily occurrence, keeping the coastal suburbs cool. This is the prime time for the Western Australian Gourmet Escape, where world-class chefs host events in the city and the Swan Valley.
December
December is hot, busy, and expensive. Average highs are 29°C, but often spike higher. The city is in full holiday mode with Christmas markets and outdoor cinemas. Expected to pay a premium for any accommodation near the water. The Sydney to Hobart yacht race isn't here, but the local sailing scene is active. If you visit in December, book your Rottnest Island ferry and bike rentals at least a month in advance.
Cheapest time to visit Perth
The cheapest time to visit Perth is during the winter months of June, July, and August. Because Perth is famous for its beaches, tourism drops when the temperature falls below 20°C. During this period, luxury hotels in the CBD often drop their rates by 30-40% compared to January. Inbound international flights are also generally cheaper. If you don't mind wearing a sweater and bringing an umbrella, you can experience the city’s world-class food and wine scene without the "sunshine tax."
When to avoid Perth
Avoid Perth in February if you are sensitive to extreme heat. It is the time of year when "eastly" winds blow hot air from the desert directly over the city, often resulting in consecutive days over 40°C. If you are looking for a swimming holiday, avoid June and July; the water temperatures drop significantly, and the weather is too unpredictable for a reliable beach itinerary. Additionally, avoid the two weeks surrounding Christmas and New Year’s if you want to avoid inflated pricing and crowded public transport.
Best time for good weather
For the most consistent "good" weather—defined as clear blue skies, no rain, and moderate temperatures—visit between October and November or March and April. These shoulder seasons avoid the blistering heat of mid-summer and the cold fronts of winter. During these months, the average temperature sits between 24°C and 28°C. This is perfect for walking the city, sitting at outdoor cafes, and visiting the islands without the risk of heatstroke or getting rained out.
Best time for fewer crowds
To avoid the crowds while still enjoying decent weather, visit in May or September. May is the tail end of autumn; the summer crowds have vanished, but the days are often still mild and sunny. September is the start of spring; most tourists wait until December to arrive, meaning you can explore the botanical gardens and coastal paths in relative peace. Avoid the Australian school holiday periods (mid-April, July, late September, and all of January) if you want to avoid long queues at major attractions.
