In spring, temperatures gradually rise from 9°C to 18°C, and in autumn, they drop from 22°C to 10°C.

The number of rainy days in spring and early autumn is moderate, so a compact umbrella will also be useful. Regardless of the season, comfortable walking shoes are an absolute necessity, as there is so much to see in Jinhae.
