PAGASA forecasts for Metro Manila on June 16, 2026, indicate daytime highs of 33–34°C with a 30% rain chance, consistent with the onset of the southwest monsoon that typically moderates peak temperatures through increased cloud cover and showers. This aligns with historical June averages near 32°C and recent sub-seasonal outlooks noting slightly above-normal warmth over Luzon, though high humidity and urban heat effects in Manila can support occasional spikes to 35°C. Current model consensus and near-term observations favor 33–35°C as the most likely range, explaining the market’s heavy weighting toward those outcomes while leaving room for variance if convective activity develops earlier or steering patterns shift.
