The wet monsoon in the described Asian region occurs mainly during which months?

• A. May to September
• B. December to February
• C. March to May
• D. October to December

Answer: (A)

The wet monsoon in this region is driven by the seasonal shift of winds and moisture that brings persistent rainfall when the land-sea temperature contrast is strongest. As the land heats up, moist air from the sea is drawn in and rises over the land, producing the main rainy spell. This pattern typically spans from late spring into late summer, with the rainfall most prominent in midsummer and tapering off by early autumn, so May through September captures the core wet-season period. The other timeframes fit dry or transitional phases: December to February is the dry season with the winter monsoon bringing cooler, drier air; March to May is the pre-monsoon period with hot, convective showers but not the sustained wet monsoon; October to December is the monsoon withdrawal and post-monsoon period with decreasing rainfall.
