Morphology
unseasonable = seasonable (transparent) = un + season + able
The adjective is derived by negating 'seasonable' with the productive prefix 'un-', so 'not typical/suitable for the time of year' is directly inferable.
Etymology
The word unseasonable comes from un- 'not' and season 'time of year', and it often describes weather or events that do not fit that time. That's why unseasonable weather is weather that is not usual for the season, like heat in autumn or snow in spring.
