The rainy season is typically the months of latter September thru November. You can count on a downpour everyday lasting anywhere to 45 minutes to 4 hours. The rain comes down hard and strong. Leaving the ground little time to become saturated in the beginning of the season. As the season lengthens the ground becomes over saturated and all the rain becomes run off to the lakes and ponds and rivers, and yes low laying areas.
Cambodians have been dealing with the rainy season for 100's of years, The attitude is you can't stop the rain from coming so enjoy it. Many locals relay on this season for their livelihood. Many become fishermen during this time of year, most outside jobs stop for this season and start back in December. This makes for ideal fishing. Cambodians have a saying they use " where there is water there is fish" I have personally found this to be true here.
Many people live in the low lying areas in our neighborhood. The wooden long boats become the main transportation to and from their homes. Also many use the boats for setting fish traps and eel traps. So maintaining your boat is a wise choice for the villagers.
The rainy season also turns into a time for selling snails by the roadside. These snail shacks are dotted along all main roads that are close to open waters bringing a source of seasonal income to the families that brave the waters in search of the snails each day, The snails are very delicious tasting and can grow quite large.
Some poor villages get swamped during the rainy season. They too live in the low lying areas and the floods come. These people are poor and have no access to boats or truckloads of dirt to help with the conditions of living through the flooding. Many are moved day to day to the higher ground, which they share with the other community members and the animals.
All to say there are people devastated by the flooding in the rainy season, but there are thous who are blessed by finding a way to fish, and find snails, some eels and make money to provide for their families. So there is a curse and a blessing that come with the rainy season.
