Traders see roughly equal odds across 23–28°C for Manila’s August 23 low because short-range model guidance remains split on nocturnal cloud cover and rainfall under the prevailing southwest monsoon. Enhanced convection tied to the Intertropical Convergence Zone can suppress radiative cooling and keep minimums near 26–27°C, while clearer breaks allow greater heat loss and push readings toward 24°C or lower. Historical August climatology shows a typical range of 24–26°C, with deviations driven mainly by timing of rain bands and boundary-layer moisture. The next 48-hour runs from global models and local PAGASA updates will likely resolve the spread before the market settles.
