Current atmospheric conditions over Metro Manila, driven by a persistent high-pressure ridge across the South China Sea, favor peak afternoon heating that aligns with the market’s near-certain 36 °C outcome. Official PAGASA guidance and model consensus indicate minimal cloud cover through the warmest hours, allowing surface temperatures at the primary reporting station to reach this threshold under typical May climatology, where urban heat-island effects routinely amplify daytime maxima. The low 20 % rain probability further supports uninterrupted insolation. A sudden increase in convective activity or thicker cloud decks before peak heating could suppress readings by 1–2 °C, but recent model runs show limited support for such development before the daily maximum is recorded.
