This 6-month period, which typically includes the months of November to April, has historically averaged about 40-70% of the annual rainfall. Understanding the rainfall pattern in Portland during March is crucial for planning and preparing for potential weather-related events.
Historical Context
According to official climate records, March is one of the wettest months in Portland, with an average monthly rainfall of approximately 4.5 inches (114 mm) based on data from the National Centers for Environmental Information (NCEI). This represents a significant contribution to the overall annual rainfall total of about 36 inches (914 mm).

Rainfall Distribution
The rainfall distribution during March is relatively consistent throughout the week, with no clear peak or dip in precipitation.

Reasons Behind the Rainfall Pattern
Portland’s unique geography, with its proximity to the Pacific Ocean, creates an orographic effect that enhances precipitation. Air masses moving from the west encounter the Coast Range and the surrounding terrain, resulting in the formation of clouds and precipitation. Climate models and historical data confirm that this phenomenon contributes to the high rainfall totals in the region.

Daytime and Nighttime Weather in Portland Oregon
March in Portland, Oregon, is characterized by a distinct difference between daytime and nighttime weather. While the daytime temperatures are mild, the nighttime temperatures tend to be cooler. This dichotomy is due to the city’s proximity to the Pacific Ocean and the prevailing westerly winds that bring cooler air masses from the coast during the evenings.
Differences in Temperature and Humidity

Wind Patterns in Portland Oregon During March
Portland Oregon’s weather in March is characterized by mild temperatures, moderate rainfall, and varying levels of sunshine. However, understanding wind patterns during this period is also crucial for predicting local weather conditions.
Wind patterns in Portland Oregon during March are influenced by a combination of factors. One significant factor is the pressure gradient set up by the high and low-pressure systems that develop over the Pacific Ocean and the North American continent. As these systems interact, they create areas of low atmospheric pressure near the surface and higher pressure at greater heights. This pressure gradient drives the wind, with winds blowing from the west to the east, from the high pressure to the low pressure.
Historical Data and Statistics
According to the National Weather Service, Portland Oregon’s average wind speed during March ranges from 5 to 10 mph (8 to 16 km/h). The highest average wind speed during March is typically observed on March 21st, with an average speed of approximately 10.5 mph (16.9 km/h). On average, the prevailing winds during March are from the west, with approximately 60% of the total wind coming from that direction.
- On average, Portland Oregon sees 12 days with gusty wind during March, which is characterized by wind speeds exceeding 25 mph (40 km/h). These events often result from strong low-pressure systems forming over the Pacific Ocean.
- The strongest wind event during March typically occurs in mid-month, with an average maximum wind gust of approximately 35 mph (56 km/h).
- The average wind direction during March is from the west, with wind direction varying little throughout the month. However, on the 15th and 22nd of March, winds tend to be from the northwest at slightly higher speeds.
Significance of Wind Patterns
Understanding wind patterns in Portland Oregon during March is essential for various purposes, including transportation planning, agriculture, and outdoor activities. For instance, wind conditions can significantly impact the timing and route of flight schedules and commercial airline operations. Additionally, wind patterns influence the dispersion and deposition of air pollutants, affecting local air quality and the overall health and well-being of the community.
Predicting Wind Patterns
Local weather forecasters use a variety of techniques to predict wind patterns in Portland Oregon during March. Among these techniques, the use of numerical weather prediction (NWP) models, such as the Weather Research and Forecasting (WRF) model, plays a crucial role. These models account for various atmospheric and land surface processes, allowing forecasters to predict wind patterns with greater accuracy and detail.
Impact of Wind Patterns on Local Weather
Wind patterns during March can directly influence local weather conditions, including precipitation, temperature, and atmospheric stability. For example, strong easterly winds can bring warmer air from the ocean, leading to increased temperatures and reduced precipitation. On the other hand, strong westerly winds can bring cooler air from the land, resulting in cooler temperatures and increased precipitation.
Portland residents, commuters, and outdoor enthusiasts should remain aware of local wind patterns during March, as this knowledge can significantly improve their daily activities, public safety, and overall quality of life.
