**Trader sentiment for Manila’s July 31 high temperature centers on the 31–33 °C range because official forecasts and climatology converge there amid the southwest monsoon.** PAGASA outlooks for July 31 project a daytime maximum of 32–33 °C with 60 % rain chance and persistent cloud cover, while historical July averages sit near 31–32 °C. These conditions—high humidity, frequent afternoon thunderstorms, and reduced solar insolation—typically cap peak readings and produce a narrow distribution of outcomes. Recent model consensus shows limited day-to-day variability, keeping 34 °C+ probabilities low and sub-30 °C outcomes unlikely. The tight split between 31 °C and 32 °C reflects uncertainty in exact timing and intensity of convection, which can shave 1–2 °C off the maximum on any given day. Updated PAGASA and global model runs over the next 48 hours will be the key catalysts that shift probabilities among these adjacent bins.
