2. Lower Humidity
Lower humidity is a defining characteristic of September weather on Martha’s Vineyard, offering a refreshing contrast to the often muggy summer months. This decrease in atmospheric moisture contributes significantly to the island’s comfortable climate during September, influencing visitor experiences and overall weather patterns.
Several factors contribute to this shift in humidity. As summer transitions to autumn, air temperatures gradually decrease. Cooler air holds less moisture than warmer air, resulting in lower humidity levels. Additionally, shifting weather patterns often bring drier air masses from the north or west, further reducing humidity. The decreased humidity enhances comfort levels for outdoor activities, making September an ideal time for hiking, biking, and exploring the island’s natural beauty. The absence of oppressive humidity allows for greater enjoyment of outdoor pursuits without the discomfort associated with high moisture levels. For example, a leisurely walk along the beach becomes more pleasant with a gentle breeze and dry air compared to the sticky, humid conditions of July or August. This improved comfort level extends to various other activities, from outdoor dining to simply relaxing on a porch and enjoying the island’s serene atmosphere.
The practical significance of lower humidity extends beyond personal comfort. It also influences the local ecosystem. Reduced humidity can create drier conditions, potentially impacting plant life and influencing the behavior of certain animal species.

-
Impact on Air Temperatures and Humidity
The ocean’s warmth moderates air temperatures, preventing drastic fluctuations between day and night. This creates a more stable and comfortable climate, particularly along the coast. The warm ocean water can also contribute to higher humidity levels, especially during periods of onshore winds. This can influence the perceived temperature and create conditions that feel warmer than the actual air temperature.
-
Marine Life Activity
Warm ocean temperatures support a vibrant marine ecosystem. Certain fish species, like striped bass and bluefish, remain active in the warmer waters, providing opportunities for fishing enthusiasts. The warm water can also influence the migratory patterns of marine mammals and sea turtles, potentially offering opportunities for wildlife sightings.
-
Influence on Fog Formation
The temperature difference between the warm ocean water and cooler autumn air can contribute to fog formation, particularly in the early morning hours. This adds a unique atmospheric element to the island’s landscape during September, impacting visibility and creating a distinct visual experience. While fog can obscure views, it can also enhance the island’s serene and mystical ambiance.
The ocean’s warmth during September is an integral component of Martha’s Vineyard’s weather patterns.

For instance, the remnants of Hurricane Earl in 2010 brought heavy rainfall and gusty winds to the island, causing some coastal erosion and disrupting ferry services.
-
Nor’easters and Coastal Storms
Nor’easters, powerful extratropical cyclones forming along the East Coast, can also impact Martha’s Vineyard in September. These storms can bring heavy precipitation, strong winds, and coastal flooding, particularly during high tides. The infamous “Perfect Storm” of 1991, while occurring in late October, exemplifies the potential intensity of these late-season storms in the region.
-
Impact on Ferry Services and Transportation

6. Extended Daylight
Extended daylight hours are a defining characteristic of September weather on Martha’s Vineyard, bridging the gap between the long days of summer and the shorter days of autumn. This gradual decrease in daylight, while subtle, plays a significant role in shaping the island’s character during September, impacting visitor activities, local routines, and the natural environment. The connection between extended daylight and September weather stems from the Earth’s axial tilt and its orbit around the sun. As the Earth progresses in its orbit, the angle of sunlight reaching Martha’s Vineyard changes, resulting in shorter days and longer nights. However, September still retains a considerable amount of daylight, offering ample opportunities for outdoor pursuits and contributing to the island’s overall appeal.
The practical significance of extended daylight in September is multifaceted. Visitors can enjoy longer beach days, extended hiking and biking excursions, and more time to explore the island’s diverse landscapes. Local businesses, particularly those reliant on outdoor tourism, benefit from the extended daylight hours, allowing for extended operating times and increased opportunities for revenue generation. For example, fishing charters can operate later into the evening, and farm stands can remain open longer to sell fresh produce. The extended daylight also influences the natural world. Plants continue to photosynthesize at a relatively high rate, contributing to the vibrant colors of early fall foliage. Animals, particularly migratory birds, begin to adjust their behaviors in response to the changing daylight patterns, preparing for their journeys south. The extended twilight periods, characteristic of September, offer unique opportunities for observing wildlife and experiencing the island’s tranquil beauty in a different light.
Understanding the connection between extended daylight and September weather on Martha’s Vineyard provides valuable insight into the island’s unique characteristics during this transitional month. It highlights the interplay between astronomical phenomena, weather patterns, and the overall island experience. Recognizing the importance of extended daylight enhances appreciation for the opportunities it presents, from extended outdoor activities to the subtle changes in the natural world. This understanding contributes to a more informed and enriching experience for visitors and residents alike, allowing them to fully appreciate the distinct qualities of September on Martha’s Vineyard. It also underscores the interconnectedness of the Earth’s systems and the impact of these systems on local environments and human experiences.
