Trader consensus on Polymarket assigns 100% implied probability to a highest temperature of 35°C in Jakarta on April 22, driven by confirmed peak observations from the Halim Perdanakusuma International Airport station—the market's resolution source via Wunderground—reaching exactly 35°C in the mid-afternoon amid partly cloudy skies and low wind speeds favoring solar heating. This aligns with Jakarta's urban heat island effect amplifying temperatures beyond BMKG's conservative 30°C forecast, consistent with recent days' 35–35.6°C highs at the same station during April's transitional climatology from wet to dry season. Realistic challenges include an improbable late-evening spike from residual heat or official data revision, but diurnal cooling patterns and finalized reports expected soon make higher outcomes negligible.
