BMKG observations at Halim Perdanakusuma International Airport—the official resolution station—recorded a peak temperature of 34°C by 1:30 p.m. WIB on May 11, reflecting sustained solar heating under partly cloudy skies and low humidity around 23% during Jakarta's dry season onset. This aligns with historical May climatology at the station, where daytime highs average 32–34°C, supported by weak La Niña transition patterns limiting convective activity. Trader consensus at 100% implied probability stems from this confirmed measurement exceeding initial forecasts of 32°C, with model ensembles showing minimal intensification potential. Realistic challenges include a late-afternoon heat burst under prolonged insolation pushing to 35°C, though low thunderstorm risk and evening cooling favor stability; final Wunderground daily archive expected post-midnight.
