There are four climatic types of islands in the Grand Line: Winter Islands, Summer Islands, Spring Islands, and Autumn Islands. Each of these islands have a climate similar to their namesake seasons. There are still different seasons on each island, with the weather in each season dependent on the type of island. The Red Line is composed of such islands grouped together.
Island Climatic ZonesEdit
The climatic type of an island is reflected upon the sea which surrounds the island itself. So, when sailing through the Grand Line the weather becomes stable, then there is most likely an island in proximity. Between the islands, the weather is inconsistent and unpredictable. A particular case of this phenomenon is the immediate first part of the Grand Line, after Twin Cape, because the influences of the first seven island climatic zones and their magnetic field make the weather chaotic.
