Official temperature readings from Singapore’s meteorological stations have confirmed a daily maximum of 33°C on June 3, driving the market’s near-certain consensus on that outcome. Midday observations reached 33.2°C at Pulau Ubin, consistent with typical June peaks of 31–32°C under the prevailing southwest monsoon regime and elevated humidity. National Environment Agency data show this aligns with seasonal norms rather than an extreme outlier, while model guidance had pointed to limited deviation. The 0.1% odds on adjacent thresholds reflect minimal scope for revision once final station reports are verified. Only an unprecedented late-afternoon spike above 34°C or a data correction could shift the result, both considered highly improbable at this stage of the day.
