Average Temperatures in Seattle in September
Seattle weather in September typically sees a noticeable drop in temperatures compared to the peak summer months, but it is still generally pleasant and comfortable. The average high temperature hovers around 70°F (21°C), making it perfect for outdoor activities. The average low temperature usually dips to around 53°F (12°C), so you will need to bring a light jacket or sweater for the evenings. You can usually experience a comfortable climate during the day and a cooler atmosphere at night.
During the early part of September, you might still experience some warm days, with temperatures occasionally reaching the mid-70s or even the low 80s (around 27°C) in some cases. As the month progresses, the temperatures gradually decrease, signaling the arrival of autumn. This transition in temperature makes Seattle weather in September ideal for layering your clothing, as you'll need to adjust to the fluctuating temperatures throughout the day.
Seattle's proximity to the Puget Sound also influences the temperature, keeping it relatively mild compared to other regions with similar latitudes. The water's moderating effect helps prevent extreme temperature swings, so you are less likely to experience extreme heat or cold during your visit. The overall climate is characterized by moderate temperatures, which makes it suitable for exploring the city and enjoying outdoor activities.
It's worth noting that the temperature can vary depending on the specific location within the Seattle area. For example, areas closer to the water may experience slightly cooler temperatures than inland locations. Monitoring the local weather forecast before you go is always a good idea so that you can pack appropriately and plan your day accordingly. In summary, Seattle weather in September provides a comfortable and inviting climate, which is ideal for a variety of activities.
Factors Affecting Seattle's September Temperatures
Several factors influence Seattle weather in September, contributing to the city's unique climate. One of the most significant factors is its location within the Puget Sound region. The Puget Sound acts as a temperature regulator, keeping the climate mild throughout the year. The water's ability to absorb and release heat slowly moderates the extreme temperatures, which results in less drastic temperature fluctuations. — Trump And Education: Key Policies & Impacts
Another factor is the influence of the Pacific Ocean, which brings moist air masses to the region. These air masses often lead to cloud cover and precipitation, which can affect temperatures. The prevailing winds, primarily from the west, bring these maritime air masses inland, contributing to the region's moderate climate. The amount of sunshine you experience during September also plays a role in the daily temperature. Clear, sunny days tend to be warmer, while cloudy days are generally cooler.
The seasonal shift from summer to autumn is another key factor affecting the temperature. The decrease in daylight hours and the changing angle of the sun's rays contribute to the gradual cooling of temperatures as September progresses. The position of the jet stream also influences the weather patterns, with its location impacting the movement of air masses and storm systems. Understanding these factors provides a more complete picture of what to expect when considering Seattle weather in September.
Tips for Dressing Appropriately for September Weather
Knowing how to dress appropriately for the weather is critical when visiting Seattle in September, as the weather can be quite variable. You should layer your clothing to adjust to the changing temperatures throughout the day. A typical outfit might include a t-shirt or a light long-sleeve shirt, a sweater or fleece, and a jacket. This combination allows you to add or remove layers as needed, ensuring your comfort throughout the day. — Ms. Sethi OnlyFans: The Truth About The Leaks
A waterproof and windproof jacket is a must-have for Seattle weather in September, as rain showers are not uncommon. Choose a jacket that is lightweight and easy to pack, so you can carry it with you. Comfortable and water-resistant shoes are also essential. Consider wearing boots or shoes that can handle wet conditions, which will protect your feet from moisture and keep you comfortable if it rains.
Accessories like a hat, scarf, and gloves can also be beneficial, especially for cooler evenings or overcast days. Bringing an umbrella is always a good idea, as you can be prepared for unexpected showers. Don’t forget to check the weather forecast before heading out each day to get an accurate idea of what to expect. This allows you to customize your wardrobe to ensure that you are ready for any situation that may arise during your visit.
Rainfall and Precipitation in Seattle in September
Seattle weather in September typically marks the transition to the wetter months, with a noticeable increase in rainfall compared to the dry summer season. You can expect an average of 1 to 2 inches of rain during September, distributed over several days throughout the month. This is still relatively moderate compared to the heavier rainfall of the winter months.
While you might experience several days of rain, the showers are usually not continuous or prolonged. You'll likely experience a mix of sunny days, overcast skies, and occasional rain showers, so having a flexible plan is important. The rain tends to be more frequent later in September, as the region moves further into the autumn season. However, the early part of September can still offer several sunny days with minimal rainfall.
It's important to note that the amount of rainfall can vary from year to year, so checking the local weather forecast before your trip is crucial. This will give you a more accurate picture of what to anticipate during your visit.

Understanding these precipitation patterns will help you plan your activities and pack appropriately.
Rainfall Patterns and Trends
Seattle weather in September exhibits a gradual increase in rainfall as the month progresses. Early September often experiences relatively dry conditions, with sunny days still prevailing. As the month advances, the chance of rain increases, along with the frequency and intensity of showers. This shift is an indicator of the seasonal transition from summer to autumn.
The Pacific Northwest's prevailing weather patterns also play a role in the rainfall patterns. Storm systems coming from the Pacific Ocean can bring rain clouds and precipitation to the region. These systems are more common in the fall and winter, which results in increased rainfall in September. The geographical features of the area, such as the Cascade Mountains, also influence the rainfall patterns. The mountains can cause orographic lift, forcing moist air masses to rise and release their moisture, which results in heavier rainfall on the western slopes.
Local microclimates also affect rainfall patterns, with some areas receiving more rain than others. For example, areas closer to the Puget Sound may experience more moisture than inland areas. Understanding these rainfall patterns helps you plan your activities and pack appropriately. Be prepared for a mix of conditions to ensure you enjoy your visit to Seattle in September.
Preparing for Rain: What to Pack
Being prepared for rain is essential when visiting Seattle in September, so knowing what to pack is critical. A waterproof jacket with a hood is a must-have, so you can stay dry and comfortable during rain showers.

Water-resistant shoes or boots are also a necessity. Select footwear that is comfortable for walking and can handle wet conditions. An umbrella can provide additional protection from the rain, particularly during unexpected showers. Consider a compact and travel-friendly umbrella, so you can carry it with you easily.
Additional accessories, such as a hat and gloves, can help keep you warm and dry, especially during cooler weather. Packing a waterproof bag or backpack can also be beneficial for protecting your belongings from the rain.
