Explanation

The given seasonal pattern — distinctly dry summers with wetter winters — matches the Mediterranean (Cs) climate, specifically the hot‑summer Mediterranean (Csa) type described as having hot, dry summers and cool, wet winters [1]. The small letter “s” denotes a summer dry season in Köppen notation, which is the defining precipitation signature of Mediterranean climates [2]. Other options are inconsistent: the China (Cfa) or West European (Cfb) types have rainfall throughout the year (no true summer dryness) with summer or winter maxima respectively [1], while the St. Lawrence/Laurentian type features very long cold winters and a large annual temperature range, not a summer‑dry regime [3].
