Seasons
Summer starts as early as March and stays until monsoon arrives. This is the driest season of Kerala considered to be off season, and rightly so. The scorching heat of the sun and extremely high temperatures make it unsuitable for visiting the coastal parts. Although, the hill stations are quite popular during this time.
Monsoons are when Kerala regains its freshness. All the waterfalls brim with water. Clouds dawning over the cliffs provide for the mystic appearance. Although, the heavy rains and downpour can be a deterrent to travel. With recent events of flooding in Kerala during monsoons, it is best to stay away during this season. Post monsoon months of October and November are good for observing the greenery of Kerala. December to February is the short window of travel season in Kerala. Also, the peak season in which the weather of Kerala is at its best. Other than the hill stations, the temperatures in the coastal and rest of Kerala is average during the winters. Although, you might feel the chills in Munnar, Thekkady or Wayanad.

From the above analysis, we can confirm that December to middle of March is the best season to visit Kerala. You may also choose October and November, if medium rains do not bother you. This season is the most suited for enjoying the waterfalls and nature exploration. Monsoon becomes unsuitable for visiting Kerala due to heavy rains but some adventurous souls might give it a try. Kerala government is also promoting monsoon tourism. You may consider April to travel. Having said that, be aware that most of the waterfalls dry up to a thin streak or nothing at all. We went to Kerala in April first week. It was quite hot. Munnar and Thekkady had pleasant weather but Kochi, Alleppey, Kovalam were hot and sunny. We experienced some rainfall while in Tiruvananthapuram. Still, it was impossible to go to beaches during day. For other details about Kerala check this post.
