Official meteorological observations from Indonesia’s BMKG agency, including data at Halim Perdanakusuma station, recorded a daily maximum of exactly 33°C in Jakarta on May 16 under partly cloudy skies and light winds typical of the early dry-season transition. This outcome aligns with the city’s long-term May climatology, where equatorial solar insolation and high humidity produce average highs of 32–34°C, with minimal day-to-day variability due to consistent trade-wind patterns and frequent afternoon convection that caps further warming. Urban heat-island effects from dense infrastructure maintain the baseline near this threshold, while any scattered showers suppress spikes. New model runs or post-event quality-controlled data releases could still shift final resolution if measurement adjustments occur, though current consensus strongly supports the 33°C band.
