Although there are various other scientific methods to forecast the weather and to determine harvests, Cambodians have their methods to foretell the future. Through traditional rituals that are often ceremoniously celebrated nationwide, Cambodians are warned of calamities, assured of good harvest and so forth.

The Royal Ploughing ceremony, or Pithi Chrat Preah Neanng Korl in Khmer, and the Festival of Water and full Moon Salutation, know as Pithi Bonn Om Touk and Ak Ambok Sampeah preah Kher in Khmer, are such ceremonies. Predictions gleaned from these traditional ceremonies for the coming year are taken very seriously.

The Festival of Water and Full Moon Salutation is celebrated usually in late October. Drippings from burning candles predict rainfall distribution to provinces across the country. The Royal Ploughing Ceremony predicts the weather, epidemics and farming conditions.

At the end of a symbolic Ploughing procession before His Majesty King Norodom Sihanouk, the royal oxen were relieved of their harnesses and led to seven golden trays containing rice, corn, sesame seeds, beans, grass, water and wine to feed. The royal oxen chose to eat out of only three trays this year and because their feast consisted of varying percentages of rice and corn while they largely ignored the trays of sesame seeds, grass, water and wine, prognostications were as follows: Farmers would enjoy a moderate output for their rice harvest but good yields in secondary crop production, especially corn and beans. Because the royal oxen only sniffed on the tray of water and turned away from the wine, the prediction was made that farmers would not suffer any serious floods.

Every year, Cambodian farmers anxiously await the predictions at the end of this ritualistic ceremony, which they observe with strong faith and belief. Most Cambodians today still consult traditional manuals before making any major decisions regarding business matters or meeting important persons, etc.
