In this article, I estimate the effect of foreign weather shocks on firm-level exports, exploiting the French firm-level customs data from 1995 to 2009. I find support for a small, negative impact of foreign temperatures on average but estimate a robust and strong differential effect across exporters, leading to composition changes. Larger firms are more negatively harmed by foreign weather shocks than small exporters. Regarding mechanisms, demand-side mechanisms (such as import demand changes) are mainly at play, whereas I find no evidence for supply-side (competition) mechanisms.
