Fill up today, or wait?
A daily Winnipeg gas price forecast — four signals, one verdict.
Wait if you can — expecting a drop of about 4¢/L by Friday.
−4¢/L expected over the next ~3 days · Today's Winnipeg median: 169¢/L
Winnipeg's weekly pattern (last 90 days)
Lower bars = cheaper days. Winnipeg's weekly cycle is strong — the classic prairie pattern jumps prices around midweek (Wednesday-ish) and lets them drift down to a weekend trough, so picking your day routinely saves a few cents per litre.
Why this verdict?
Winnipeg's weekly cycle takes ~3.0¢ off.
- Weekly cycle: -3.0¢
- 7d vs 21d trend: -1.0¢
- WTI crude (5d): 0.0¢ — now $84.25 USD/bbl
- wholesale rack (5d): 0.0¢

What's driving today's call
The predictor blends four signals. Two are local (Winnipeg's 7-day trend and its strong weekly cycle), two are upstream commodities that pass through to the pump with a known lag.
How the prediction is built
- Weekly cycle (a heavy weight in Winnipeg). We compute the median Winnipeg price for each day of the week from the last 90 days. Winnipeg's prairie cycle — midweek peak, weekend trough — is strong and consistent, so this signal often drives the verdict.
- Trend. 7-day moving average vs 21-day moving average. If the short average is above the long average, prices are climbing — and we project 60% of that move forward over three days.
- WTI crude. Roughly $1/barrel translates to ~0.85¢/L at the Canadian pump, with a 5–10 day lag. We look at the change in the past 5 days.
- Winnipeg wholesale rack. The upstream local signal: pump prices typically follow rack moves within 1–3 days, and the prairie rack swings on Alberta and Saskatchewan refinery turnarounds and seasonal demand. A rack spike overnight is one of the strongest "fill today" signals, even mid-cycle.
Each component returns a signed cents-per-litre value. We add them up, classify the total against simple thresholds, and call it. The model is intentionally simple — it's a heuristic, not a black-box ML model.
FAQ
Does Winnipeg have a weekly cheap day?
Emphatically yes. Winnipeg runs a classic prairie Edgeworth cycle — a sharp jump around midweek (Wednesday is the usual reset day), then a slow discounting drift down into a weekend trough. The day-of-week spread here is among the widest in Canada, routinely a few cents per litre, which is why the weekly-cycle signal carries real weight in our model. Wholesale rack moves and crude swings layer on top of the cycle rather than replacing it.
How accurate is this prediction?
We give you a verdict and a confidence meter (out of 5). High confidence means all four signals (weekly cycle, recent trend, WTI crude, wholesale rack) point the same direction. Low confidence means the signals disagree. We tune the thresholds based on how the forecast plays out. Treat it as a strong nudge, not a guarantee — geopolitics and refinery outages can override it.
What's the 'rack price'?
The wholesale price paid by gas stations to fuel terminals — posted for the Winnipeg terminal every morning. Winnipeg has no refinery of its own; fuel arrives by pipeline and rail from Alberta and Saskatchewan refineries, so the local rack tracks the prairie wholesale market. When the rack jumps overnight, retail prices typically follow within a day or two, so a rack spike is one of the strongest 'fill today' signals.
Where does the data come from?
Pump prices: scraped hourly from public Winnipeg station feeds. WTI crude: free FRED API from the St. Louis Fed (series DCOILWTICO). Wholesale rack: Petro-Canada's public daily terminal postings for Winnipeg, with NRCan wholesale data as a fallback. All sources are free and open.
