"Climatic" = relating to weather conditions or climate; "climactic" = relating to or forming a climax, the most intense or decisive moment.
Adjective: relating to CLIMATE (weather conditions, temperature, precipitation, etc.). "Climatic changes" = climate changes. "Climatic conditions" = weather-related conditions. Comes from "climate". Has nothing to do with narrative or dramatic climax.
The region has seen significant climatic shifts over the past century, with average temperatures rising by two degrees.
Farmers must adapt their techniques to changing climatic conditions as rainfall patterns become less predictable.
The expedition was delayed due to adverse climatic conditions in the mountain pass.
Adjective: constituting or relating to a CLIMAX (the point of maximum intensity, tension, or emotion in a narrative, performance, or event). "The climactic scene" = the peak scene, the climax scene. "A climactic moment" = the pivotal, most intense moment. Comes from "climax".
The climactic battle at the end of the film had audiences on the edge of their seats for nearly twenty minutes.
After years of preparation, the championship match was the climactic moment of her athletic career.
The climactic chapter of the novel resolves every subplot and delivers the emotional payoff readers had been building toward.
Common mistake
The error almost always goes in one direction: using "climatic" when you mean "climactic". "The climatic scene of the movie" is incorrect if you mean the climax scene — that is the "climACTIC scene". "Climatic" is only used for weather-related CLIMATE. If you are not talking about temperatures, rainfall, or weather patterns, you probably want "climactic".
Trick to remember it
CLIMATIC contains CLIMATE inside (clim-AT-ic = climATE + -ic). If you can substitute "relating to climate/weather", use CLIMATIC. CLIMACTIC contains CLIMAX inside (clim-ACT-ic = climAX + -ic). If you can substitute "forming the climax" or "pivotal", use CLIMACTIC. The extra C in climaCTic = aCTion = the ACTing climax of the story. Climate = CLIMATIC. Climax = CLIMACTIC.
Quick rule
Climatic = relating to weather climate (temperature, rainfall, weather patterns). Climactic = relating to the climax, the peak moment (of a story, performance, or event).
Did you know?
The confusion between these two words appears even in newspaper headlines and documentary subtitles. A famous type of error: a climate change documentary incorrectly using "climatic" when the text clearly refers to a pivotal narrative moment. The visual similarity between the two words (they differ by only two letters: cliMAtic vs cliMACtic) makes them particularly difficult to distinguish when reading quickly.

Exercise 3 · Form the word
Climatic = relating to weather climate (temperature, rainfall, weather patterns). Climactic = relating to the climax, the peak moment (of a story, performance, or event).
