Persistent April heatwave conditions, with BMKG-observed highs frequently exceeding 35°C at stations across Greater Jakarta including recent peaks near 35.6°C, have positioned 35°C as the market-implied frontrunner at 65% probability for the highest temperature at Halim Perdanakusuma International Airport on May 1. Despite BMKG's latest forecast capping daytime highs at 31°C amid light rain (hujan ringan) and high humidity (69–98%), traders anticipate limited suppression from clouds during the dry season onset, bolstered by urban heat island effects and historical May averages around 33°C. Updated hourly observations and model runs from BMKG expected throughout the day could shift probabilities as actual conditions unfold.
