Divergent ensemble forecasts from global models like ECMWF and GFS are fueling tight odds around 28-32°C for Sao Paulo's March 23 high temperature, with traders split on whether a strengthening subtropical high will push peaks toward 30°C or higher or if afternoon sea breezes and scattered clouds cap it nearer 28°C. INMET's latest guidance points to partly cloudy skies and highs in the upper 20s to low 30s Celsius, aligning with March historical averages of 27-29°C but tempered by urban heat island effects and lingering moisture from recent Atlantic disturbances. Minimal precipitation risk (under 20%) favors warmer outcomes, though model spread reflects uncertainty in boundary layer mixing, keeping 32°C+ viable at 25.5% amid recent upward revisions in heat index projections.

The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day by the Forecast for the Sao Paulo-Guarulhos International Airport Station once information is finalized, available here: https://www.wunderground.com/history/daily/br/guarulhos/SBGR.
To toggle between Fahrenheit and Celsius, click the gear icon next to the search bar and switch the Temperature setting between °F and °C.
This market can not resolve to "Yes" until all data for this date has been finalized.
The resolution source for this market measures temperatures to whole degrees Celsius (eg, 9°C). Thus, this is the level of precision that will be used when resolving the market.
Any revisions to temperatures recorded after data is finalized for this market's timeframe will not be considered for this market's resolution.
