Seattle's dark winter days are finally giving way to more light.
The big picture: The city will gain almost four hours of daily sunlight between the spring equinox Thursday and summer solstice on June 20, per Time and Date.
How it works: Our northern latitude means we gain daylight faster in spring than places closer to the equator as the sun's path shifts northward.
- The summer solstice marks the longest day — when we get nearly 16 hours of daylight — and the start of the sun's southward retreat.
Yes, but: Spring isn't all rosy.
- It's also prime pollen time, and allergy season is getting longer in many parts of the country.
