These patterns reveal distinct variations across the islands and within specific locations based on topography and wind direction.

Hawaii’s unique topography, featuring volcanic mountains and varying elevations, significantly influences rainfall distribution. The northeastern trade winds, prevalent during March, force moist air upwards against the mountains, leading to orographic rainfall. This effect results in significantly higher rainfall on the windward (northeastern) sides of the islands. For example, the windward slopes of Kauai and the Big Island typically receive substantially more rainfall than leeward (southwestern) areas. Conversely, leeward sides experience drier conditions, creating a “rain shadow” effect. These variations necessitate location-specific planning for outdoor activities and agricultural practices. Understanding these typical rainfall patterns allows for more effective water resource management and drought preparedness strategies.

Variability in rainfall also influences the risk of flash flooding, particularly in areas with steep terrain. Historical March data reveals periods of intense rainfall, which can saturate the ground and lead to rapid runoff. This information is crucial for developing effective flood mitigation measures and informing public safety protocols. While precise rainfall amounts for March 2025 remain unpredictable, understanding historical patterns and the influence of topography allows for improved preparedness and informed decision-making.

Furthermore, changes in sea surface temperatures, influenced by phenomena like El Nio and La Nia, can impact rainfall patterns.
