Window Seat Sun Exposure Guide

Understand how sunlight changes during travel and how to choose a window seat for sun, shade, or balanced exposure.

Why window seat sun exposure changes

Sun position shifts throughout the day, and your route direction determines which side gets more light. Clouds, season, and latitude also affect the sun-shade balance across the journey.

If you want a sunny seat, you need the side that faces the sun for most of your trip. If you want shade, pick the opposite side.

Flights, trains, and buses

  • Flights: Sun exposure depends on heading and time. Eastbound morning flights get more sun on the right side, while westbound afternoon flights often light the left side.
  • Trains: Routes with long straight segments make seat window shade choices more predictable.
  • Buses: Urban routes can alternate shade quickly, but longer routes behave more like trains.

Quick tips for sun and shade

  • Morning travel: choose the side facing east for more sun.
  • Afternoon travel: choose the side facing west for more sun.
  • If you want shade, choose the opposite side.
  • Use a sun-shade or window shade when exposure is high.
