On review aggregator website Rotten Tomatoes, the film has an approval rating of 58% based on 24 reviews, with an average rating of 6.05/10. Susan Wloszczyna of RogerEbert.com described Strange Weather as "a rather dour road-trip movie" and, while admiring "the delicious details that Holly Hunter injects into her performance", concluded that "not even Hunter, who eventually wears out her welcome, can keep Strange Weather from going off the cliff." Ben Kenigsberg wrote in the New York Times that the film is "a case of excellent actors' straining to elevate a contrived screenplay", and one that ultimately delivers "a catharsis more meaningful for character than for her audience."
