Trader consensus on Polymarket assigns near-certain implied probability to a highest temperature of 35°C at Halim Perdanakusuma International Airport on April 25, driven by BMKG observational data confirming an early afternoon peak of 35°C amid partly cloudy skies and urban heat island amplification in Jakarta. Despite initial hourly forecasts projecting maxima of 30–31°C under light rain and 70–95% humidity, actual readings exceeded model conservatism, consistent with recent days' patterns like 35°C on April 22 and frequent April spikes above the 32°C climatological average due to concrete heat retention and brief cloud breaks. Realistic challenges include a late-day heat burst to 36°C+ if winds weaken further, though incoming evening showers per BMKG updates make this unlikely; final Wunderground daily maximum expected by midnight.
