Coastal Oregon in March experiences a transition between winter and spring. Typical conditions include cool temperatures, ranging from highs in the mid-50s Fahrenheit (low teens Celsius) to overnight lows in the 40s Fahrenheit (single-digit Celsius). Rainfall is common, though less frequent than in the winter months. Ocean temperatures remain cold. Visitors should anticipate variable conditions and be prepared for both sun and rain, sometimes within the same day. Strong winds are also possible.
Understanding these conditions is crucial for planning a trip to the Oregon coast during this time. Proper preparation allows visitors to enjoy the dramatic scenery, explore tide pools during lower tides, and experience the unique coastal ecosystem with its migrating gray whales. Historically, March marks the beginning of the tourist season’s ramp-up, offering a less crowded experience compared to the summer months. While the weather can be unpredictable, the off-season rates and tranquility can be appealing.
