6. City-Specific Considerations

Seattle has some unique weather-related quirks and cultural norms to keep in mind:

Rain Culture:

• Rain in Seattle is usually light and drizzly rather than heavy downpours.

Snow and Ice:

Seasonal Affective Disorder (SAD):

• The long, gray winters can affect mood and energy levels. Consider investing in a light therapy lamp if you’re staying long-term.

Traffic and Weather:

• Rain significantly impacts traffic in Seattle. Allow extra time for commutes during wet weather, as roads can become slippery and congested.
