Current forecast models from the Indonesian Meteorological, Climatological, and Geophysical Agency and global ensembles point to a peak afternoon temperature of 33–34°C in Jakarta on May 19, driven by typical May dry-season subsidence, reduced cloud cover, and enhanced urban heat-island effects. Minor differences in boundary-layer mixing, sea-breeze timing, and localized humidity gradients create the narrow spread between these two outcomes, while historical May maxima in the region average 32–33°C. Traders are weighing the latest model runs for any shifts in wind patterns or insolation that could push the daily high across the 34°C threshold before resolution.

This market will resolve to the temperature range that contains the highest temperature recorded at the Halim Perdanakusuma Intl Airport Station in degrees Celsius on 19 May '26.
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 Halim Perdanakusuma Intl Airport Station once information is finalized, available here: https://www.wunderground.com/history/daily/id/jakarta/WIHH.
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.Current forecast models from the Indonesian Meteorological, Climatological, and Geophysical Agency and global ensembles point to a peak afternoon temperature of 33–34°C in Jakarta on May 19, driven by typical May dry-season subsidence, reduced cloud cover, and enhanced urban heat-island effects.
