Hong Kong Observatory forecasts point to normal-to-above-normal August rainfall amid a continuation of the unusually wet pattern seen in July, when totals reached 790 mm. Early-month accumulation already stands near 125 mm through August 5, driven by the southwest monsoon and scattered thunderstorms. Traders assign the highest implied probabilities to the 650–700 mm and 700 mm+ brackets because active tropical cyclone development or slow-moving rainbands could easily push monthly totals well above the 377–453 mm climatological average. Conversely, the sizable probabilities on sub-425 mm outcomes reflect the risk that a strengthening subtropical ridge suppresses convection for extended periods. Model spread on cyclone tracks and intensity through the remainder of the month sustains the close clustering across mid-to-high ranges.
