NEA's latest 24-hour forecast for April 12 anticipates thundery showers mainly over northern, eastern, and central Singapore in the late afternoon and evening, fostering trader consensus on a narrow 31°C (39.5%) to 32°C (38.5%) highest temperature range amid potential for 34–35°C under clearer skies. This split reflects subtle uncertainties in shower timing relative to peak heating hours around 2–4 p.m., when solar insolation drives urban heat island effects in station readings; earlier or denser cloud cover favors 31°C, while delayed onset allows 32°C as seen on April 11 (32°C observed). The first fortnightly outlook confirms wetter inter-monsoon conditions with frequent afternoon convection capping highs below climatological April averages near 31.5°C, with updated NEA guidance expected multiple times daily.
