Busan’s coastal location under the influence of the North Pacific High is sustaining above-average July highs amid ongoing heatwave advisories from the Korea Meteorological Administration. Recent model consensus points to daytime maxima near 31–33 °C on July 20, with the slight edge to 32 °C reflecting limited cloud cover and weak sea-breeze moderation expected that day. Monsoon (Jangma) moisture and any late-day showers remain the chief variables that could cap the peak one degree lower or allow brief clearing to push it higher. Historical July climatology for Busan shows mean highs of 27–29 °C, so the current pattern represents a clear positive anomaly driven by persistent subsidence and high humidity that reduces nocturnal cooling. Updated KMA and global model runs issued in the next 48 hours will refine the exact threshold.
