The Mundakan crop season in Kerala is characterized by moderate rainfall. This is because the monsoon rains, which are the main source of rainfall in Kerala, are usually at their peak during this time of year. The monsoon rains bring much-needed moisture to the soil, which helps to promote the growth of crops. In addition, the moderate temperatures during the Mundakan crop season are ideal for crop growth.
The other options are incorrect because they do not accurately describe the climate conditions during the Mundakan crop season. Heavy rainfall is not characteristic of this time of year, as the monsoon rains are usually at their peak during the previous months. Dry weather is also not characteristic of this time of year, as the monsoon rains provide much-needed moisture to the soil. Low temperatures are also not characteristic of this time of year, as the temperatures are usually mild during the Mundakan crop season.
