Trader consensus on Polymarket heavily favors 13°C as Munich's highest temperature today at 40% implied probability, closely tracking the latest Deutscher Wetterdienst (DWD) point forecast and ECMWF ensemble mean projecting a daytime maximum near 13°C under persistent overcast skies. Cool northerly airflow from a blocking high-pressure ridge north of the Alps suppresses solar heating, while cloudy conditions—evident in recent satellite imagery—cap peak temperatures below early April climatological norms of 12–14°C. Overnight model runs from GFS and ICON refined downward from prior 14–15°C estimates due to amplified cloud cover predictions, shifting odds away from 15°C or higher (now 7.5%). As observations accumulate at Munich airport station through afternoon, potential brief cloud breaks could nudge toward 14°C, with hourly DWD updates providing key resolution cues amid typical spring forecast uncertainty.
