Stable high-pressure systems and consistent meteorological models produced zero precipitation forecasts for the Baku City Circuit throughout the September 26 race window, driving the overwhelming trader consensus on a dry outcome. Local services and F1 briefings highlighted clear skies, track temperatures near 43°C, and only moderate northerly winds as the primary variable, with no incoming fronts or moisture from the Caspian region. This alignment across short- and long-range data reinforced near-certain implied probabilities for no rain during the grand prix. Residual uncertainty remains limited to rare, localized convective cells or forecast model errors, though such events have historically been absent in Baku during late-September sessions.
