is called the Northeast Monsoon Season. The prevailing winds are northerly to northeasterly. It is normal to see heavy rainfall throughout the nation thanks to monsoon surges. The first intermonsoonal season, from late March through May, sometimes has thunderstorms, and afternoon temperatures can rise above 90 degrees F (32 degrees C). For the most part, the winds in this period are light and variable. Following this is the Southwest Monsoon Season, which is marked by southeasterly to southerly winds and Sumatra squalls with wind gusts between 25– 50 mph (40–80 kph). There are sometimes showers and thunderstorms during the afternoons. Finally there is the intermonsoonal season from October through November. Similar to the other intermonsoonal period, thunderstorms are possible. It is a bit wetter during the second intermonsoonal period than during the first.

Heavy rainfall is common in Singapore, particularly during the monsoon season.
