Cheapest Month to Fly Singapore to Perth in 2026

Updated: September 2026.

TL;DR

For a Singapore traveller booking Singapore to Perth in 2026, February is the cheapest month, with Scoot round-trip economy dipping to SGD 260 to SGD 340 all-in during the mid-month school-holiday-adjacent low. Mid-May and early November are the second and third cheapest windows. Peak fares hit in the mid-June to August Perth winter school holidays (SG students visit family in Perth), late September to October wildflower and Margaret River wine tour season, and December southern-summer school holidays where Scoot rises to SGD 750 to SGD 1,100 round-trip.

The verdict at a glance

Book Singapore to Perth for February travel if the calendar allows. It is the cheapest window because it falls between the December school-holiday peak and the March school-term restart, with no major festival, sporting, or wildflower demand. Second-cheapest is mid-May, third-cheapest is early November. Any other month varies widely by day-of-week and departure date.

The Singapore to Perth route is one of the shortest Australia routes from Singapore at 3,900 kilometres block distance, roughly 5 hours 25 minutes westbound and 4 hours 55 minutes eastbound. Multiple carriers serve the route (Scoot, Singapore Airlines, Jetstar, Qantas), which keeps competitive pressure on fare buckets year round.

Why February is cheapest

Western Australia public schools return from summer break in early February per the Department of Education Western Australia 2026 term calendar (Term 1 begins Monday 2 February 2026). Perth family-visit inbound demand from Singapore drops sharply after the January tail. Perth's summer wine and coastal tourism season for international visitors is winding down as December-January peak passes. No major sporting or cultural event pulls high inbound tourist demand: the Perth Cup and Fringe World Festival run in January, not February.

Scoot maintains its base Singapore to Perth frequency at 6 to 7 weekly flights year round, with fare buckets adjusting to demand. In February, the airline releases lowest-tier fare buckets (SGD 130 to SGD 170 one-way excluding baggage) on more flights, and Scoot's Escape Sale (typically launched late January) frequently drops February SIN to PER to SGD 260 round-trip.

Why late September and October are expensive

Tourism Western Australia's annual wildflower promotion drives September to October to a demand peak. Per Tourism Western Australia's published wildflower calendar, WA hosts more than 12,000 wildflower species with roughly 60 percent endemic (found nowhere else). Peak bloom moves south through the season, roughly Kalbarri and the Coral Coast in July-August, the Perth region and Avon Valley in September, and the South West and Margaret River in October-November.

Margaret River is Australia's second-most-visited wine region after the Yarra Valley (Melbourne). October is peak Margaret River season for weekend tour bookings from Perth, driving flight demand from Singapore, Melbourne, and Sydney. Perth Airport reported roughly 15.4 million passengers in the financial year 2024 to 2025, with international traffic concentrated in the September-October and June-July peaks.

Carrier comparison 2026

Scoot operates the most frequency and the lowest lead-in fares on Singapore to Perth. Aircraft: Boeing 787-8 or Airbus A320neo. Baggage: 10 kg carry-on and 30 kg checked available as add-ons or included in Scoot Plus. Time in seat: 5 hours 25 minutes westbound.

Singapore Airlines operates Singapore to Perth on Boeing 737-8 MAX or Airbus A350-900 aircraft with 30 kg checked baggage included in economy Standard fare and above. SIA typically runs 2 to 3 daily flights, with more frequency around WA school holidays. Time in seat matches Scoot.

Jetstar Airways (Qantas Group) operates a modest Singapore to Perth service typically via 787-8, comparable to Scoot's price point but with different baggage rules (7 kg carry-on standard, 20 kg to 30 kg checked as add-ons). Jetstar frequently launches Friday Fare Frenzy sales for SIN to PER at SGD 250 to SGD 350 round-trip.

Qantas operates a limited SIN to PER route mostly for connecting Kangaroo Route traffic (Singapore to London or Frankfurt via Perth on 787-9). Economy point-to-point SIN to PER pricing is typically the highest of the four carriers.

Booking lead time

For February travel, the sweet-spot booking window is 3 to 5 months out, so book between September and November of the prior year for the deepest fares. Scoot's Escape Sale in late January routinely drops February SIN to PER to SGD 260 round-trip, but seat inventory at that fare is thin.

For June to July WA school holiday travel, book 5 to 7 months out (December to January) to lock the lower fare buckets. Waiting until March or April routinely costs SGD 200 to SGD 400 more.

For September to October wildflower and wine season, book 6 to 9 months out (January to March). Waiting to May or June closes access to the SGD 500 to SGD 600 fares and pushes travellers into SGD 700+ pricing.

For December southern-summer school holidays (SG Dec 1 to Jan 6 school break maps closely to WA summer break), book 9 to 12 months out. December travel is the least flexible on price.

Perth weather and best travel windows

Per the Australian Bureau of Meteorology's Perth climate data (Perth Metro station 009225 and Perth Airport station 009021), Perth summer average daily maximum in January is roughly 31.4 degrees Celsius with 8 to 12 days above 35 degrees. February is similar. Winter (June to August) daily maximum is roughly 19 degrees, with rainfall peaking in June-July.

The most comfortable travel windows for Singapore visitors are late March to early May (autumn), and late September to November (spring). Perth's coastal beaches, Cottesloe and Scarborough, are swimmable from November to April. Rottnest Island quokka trips and Fremantle brewery tours work year round.

For a cost-vs-weather optimisation, mid-May is the sweet spot: fares SGD 290 to SGD 380 round-trip on Scoot, and Perth daily max still around 22 to 24 degrees.

Use case segmentation

For the flexible-date leisure traveller, book February to save SGD 400 to SGD 800 versus December. Any WA activity except wildflowers and Margaret River peak-season is available. For the SG-based Perth family-visit traveller (children of WA-based parents), the June to July or December windows are non-negotiable but you can offset cost by booking 6+ months out.

For the wine-and-food enthusiast targeting Margaret River, September to November is worth the SGD 200 to SGD 300 fare premium. For wildflower photography, book late August to September and target Kalbarri, Coalseam, and the Avon Valley.

For the budget-first traveller open to any Australia city, Melbourne round-trip SGD 350 to SGD 470 in April to May and Adelaide SGD 300 to SGD 400 in February to March are alternatives to Perth if the itinerary is flexible.

When this pattern breaks

Weather-related demand shifts: an unusually wet or dry WA winter shifts wildflower season timing by 2 to 4 weeks either direction. In 2024, wildflower peak was 3 weeks late due to a wet cold spring; in 2022, it was 2 weeks early after a dry warm autumn. This propagates to September to October flight demand.

Sporting event peaks: WACA cricket tests (Ashes years), AFL finals with West Coast Eagles or Fremantle Dockers deep runs, and major Fringe World or Perth Festival years each pull temporary demand spikes to specific weekends. These are 1 to 3 percent of annual bookings but push spot fares up 30 to 50 percent for the target week.

Currency shifts: a stronger AUD versus SGD makes Perth trips relatively more expensive on the ground but does not change the flight fare mechanics much. A weaker AUD does the reverse.

When should I book flights for February 2026 travel to Perth?

Book 3 to 5 months out, so between September and November 2025 for February 2026 departure. Scoot's Escape Sale in late January of each year routinely drops February SIN to PER to SGD 260 round-trip, but seat inventory at that lowest fare is thin.

Should I fly during Perth's winter (June to July) or wildflower season (September to October)?

Winter is cheaper on some months, but June and July fall in WA school holidays and Singapore school holidays, driving demand. September to October is the wildflower and Margaret River wine peak with Scoot round-trip SGD 580 to SGD 820. For pure cost optimisation, avoid both by targeting February or mid-May. For wildflower photography or wine tours, budget the fare premium and book 6 to 9 months out.

Per Tourism Western Australia's published wildflower calendar, wildflower season runs from June to November across Western Australia, with peak bloom moving south.
