Ongoing southwest monsoon flows, reinforced by nearby Tropical Depression Henry, are the main driver keeping Manila’s July 3 high-temperature odds clustered around 30–33 °C. Scattered thunderstorms and persistent cloud cover limit solar heating, while variable convective timing and localized clearing can still allow brief spikes into the low-to-mid 30s. PAGASA’s latest guidance points to a 32 °C daytime peak with a 40 % rain chance, aligning with climatological July averages near 31 °C yet leaving room for model spread in boundary-layer moisture and wind speed. Traders therefore assign comparable probabilities to 30–33 °C outcomes, reflecting uncertainty in exactly how much insolation will reach the surface amid the disturbed monsoon pattern.
