A cycle starts when the city average jumps at least 8 c/L above its low of the three days before, and at least 4 c/L more than the capitals' median moved, so a market-wide rise is not a cycle; it runs to the next such jump. Prices are the city daily average on those days.

Price cycle questions

What is the best day to buy petrol in Perth?

Wednesday was the cheapest day in 11 of the last 11 full weeks to 9 Nov, about 6.8 c/L under that week's average once the overall price movement is removed. It is a guide only: where prices sit in the cycle matters more, so check the chart above.

How long is the petrol price cycle in Perth?

Perth prices jumped 43 times in the last year, and a Perth cycle ran a median of 7 days from one jump to the next. Prices rose a median 16.3 c/L from a low to the peak, over about 1 days, then fell 15.9 c/L to the next low. No two cycles are the same length, so read the dated chart rather than a weekday rule.

Where is Perth's petrol price cycle now?

U91 averaged 217.5 c/L on 9 Nov. That is 13.9 c/L below the 5 Nov high (4 days earlier). It is 3.3 c/L below the 4 Nov low. The last turn was a high, so prices are on the easing side of the cycle.

When will petrol prices go down in Perth?

They are already easing: the last high was 4 days ago. In past Perth cycles prices kept easing for a median of about 6 days after a high before the next jump. Past cycles are a guide, not a promise: the forecast page gives the day-by-day estimate and how often it was right.

What is the Unleaded 91 price cycle?

In the big capitals, retailers raise prices sharply over a day or two, then let them ease over the following weeks. The pattern comes from retail pricing, not from wholesale costs.
