Spring break SeaTac rental weather forecast planning (March–April)

Detailed answer

Spring break weeks (March–April) align with **54–59°F** average highs and **2.6–3.5 inches** monthly precip — **8–11 rain days** per Open-Meteo normals. Mount Baker or Stevens Pass day trips may still require **chains** through April; book **AWD** if ski weekends are on the itinerary. Kayak economy **$29/day** tempts budget travelers, but **+$32/day** SUV upgrade reduces hydroplaning risk on I-5.
