Implications of El Nino on Seattle Weather in December
As the Pacific Northwest braces for the arrival of winter, the presence of El Nino can significantly impact Seattle’s climate during December. El Nino, a complex weather phenomenon characterized by warmer-than-average sea surface temperatures in the Pacific Ocean, can lead to a multitude of effects on the region’s weather patterns.
Increased Precipitation, Weather in seattle for december
During a typical El Nino event, Seattle can experience increased precipitation during December, with a greater likelihood of rain and wetter-than-average conditions. This is due to the shifting jet stream, which brings moist air from the Pacific Ocean into the region, resulting in an uptick in rainfall. According to the National Weather Service, El Nino events tend to bring above-average rainfall to the Pacific Northwest, with Seattle seeing an average increase of 1-2 inches of precipitation during December.
“It’s not uncommon for El Nino to bring above-average rainfall to the Pacific Northwest, including Seattle. The increased moisture from the Pacific Ocean can lead to a more active winter weather pattern, with a higher chance of rain and snow in the region.” – Chris Burke, Meteorologist, National Weather Service
Moreover, the increased precipitation can lead to a higher risk of floods and landslides in the region, making it essential for residents to be prepared for the changing weather conditions.
Temperature Shifts
El Nino events can also lead to shifts in temperature, with a greater likelihood of warmer-than-average temperatures in Seattle during December. This is due to the warmer ocean waters, which can lead to a reduction in the temperature difference between the air and the ocean, resulting in milder weather. However, it’s essential to note that temperature anomalies can vary from year to year, and some El Nino events may see colder-than-average conditions.
Impacts on Regional Climate
The impacts of El Nino on Seattle’s climate during December can have far-reaching effects on the region’s climate. The increased precipitation can lead to a higher risk of flooding and landslides, while the warmer temperatures can disrupt the region’s ecosystems and potentially lead to changes in tree species composition. Furthermore, the shifting weather patterns can affect the region’s agriculture, with some crops benefiting from the increased moisture and others struggling with the cooler-than-average temperatures.
Preparing for El Nino
While El Nino events can be unpredictable, there are steps that residents can take to prepare for the changing weather conditions. By staying informed about the latest weather forecasts and warnings, residents can take necessary precautions to protect themselves and their property from the impacts of El Nino. Additionally, being aware of the potential risks associated with flooding and landslides can help residents take proactive measures to ensure their safety and the safety of those around them.

Designing Outdoor Spaces to Withstand Seattle’s December Weather
As the rain and gray skies of December settle over Seattle, architects and landscape designers must carefully consider the materials and structure of outdoor spaces to ensure they can withstand the inclement weather. A well-designed outdoor space can be a haven for Seattleites, providing a peaceful retreat from the drizzle and gloom. However, a poorly designed space can quickly become a soggy, unpleasant mess.
Designing outdoor spaces for Seattle’s December weather requires a deep understanding of the region’s unique climate. The constant rain, gray skies, and mild temperatures create a challenging environment that demands specific design considerations.
Material Selection
When selecting materials for an outdoor space in Seattle, it’s essential to choose ones that can withstand the wet and gray conditions of December. Here are some key considerations for material selection:
- Waterproof membranes: Incorporate waterproof membranes, such as EPDM or PVC, to prevent water from seeping into the space and causing damage.
- Durable finishes: Use durable finishes, such as stained or sealed wood, to protect against the elements and extend the lifespan of the materials.
- Weather-resistant coatings: Apply weather-resistant coatings, such as acrylic or polyurethane, to protect metal surfaces from rust and corrosion.
- Permeable pavers: Use permeable pavers to allow water to drain through the surface, reducing the risk of puddles and flooding.
Structural Considerations
In addition to material selection, architects and landscape designers must also consider the structural integrity of the outdoor space. Here are some key considerations:
- Drainage systems: Design a robust drainage system to ensure that water can quickly and efficiently drain away from the space.
- Structural support: Provide adequate structural support, such as steel beams or columns, to withstand the weight of the materials and any external loads.
Sustainable Design
Designing outdoor spaces in Seattle can also be an opportunity to promote sustainable design practices. Here are some ideas:
- Living walls: Incorporate living walls, such as green roofs or vertical gardens, to provide insulation, reduce stormwater runoff, and create a habitat for local wildlife.
- Permeable surfaces: Use permeable surfaces, such as permeable pavers or porous concrete, to allow water to infiltrate the ground, reducing stormwater runoff and recharging groundwater aquifers.
- Sustainable materials: Specify sustainable materials, such as reclaimed wood or low-maintenance plantings, to reduce the environmental impact of the project.
