How to read the outlook
What to check after the forecast
The chart estimates the next 30 days. Before you fill, compare its direction with recent reports from nearby stations.
Outlook flat or easing
If you can wait, recheck before filling a full tank. Small movements can still matter when you combine timing with a cheaper station.
Confidence matters
Petrol cycle timing is only used for Sydney, Melbourne, Brisbane, Adelaide and Perth, and only when repeated price data supports it. Diesel, LPG and other cities use trend guidance with wider uncertainty.
How it is calculated
How FuelRadar estimates the next 30 days
The forecast checks recent city prices, wholesale fuel costs, crude oil and the Australian dollar. Its range gets wider further into the month.
Figures checked
90 days of daily city-average prices per fuel type, terminal gate prices from the Australian Institute of Petroleum, AUD/USD exchange rates, Brent crude oil prices, and the detected position within the current local price cycle.
How the estimate is made
The forecast checks the city's recent price cycle, then smooths the last 90 days of prices to estimate the next likely move. It shows a guide price and likely range, with later dates treated as less certain.
Updated overnight
Outlooks refresh overnight. Same-day price moves are not reflected until the next refresh, so use the map for reported station prices and update times.
Where the forecast is strongest
The first week has the narrowest range in the five capital-city cycle markets: Sydney, Melbourne, Brisbane, Adelaide and Perth. Diesel, LPG and cities outside those five use recent price movement instead of estimated peak and low dates.
What the forecast can miss
FuelRadar lists cited reports about refinery outages, crude-oil moves, exchange-rate pressure and other recent events beside the forecast. These reports explain uncertainty but do not change the cents estimate until reported retail or wholesale prices move.
Price-report coverage
Reporting rules and update times differ by state. NSW, Queensland and Victoria use government-backed reporting, while WA publishes fixed daily prices. Forecasts can inherit those delays, so check the station update time before driving.

- FuelRadar matches saved forecasts with prices later reported for the same city and fuel type. Once a city has enough samples, the accuracy page publishes the average difference in cents per litre and the sample size.
Price forecast FAQ
Sydney, Melbourne, Brisbane, Adelaide and Perth are the five recognised petrol-cycle markets and usually have the clearest short-term patterns. Diesel, LPG and other cities use recent price trends with wider uncertainty. The cents figure is a guide, not a promise.
