Compare both sides of the harbour
The official Copenhagen harbour guide provides a starting point for exploring the waterfront. Areas around Islands Brygge and Kalvebod offer different positions relative to the water and nearby buildings. A harbour address alone does not tell you which part of the sky is clear.
Open public space is not the same as a café
Kalvebod Bølge is one example of a waterfront public space. If you want table service, identify a specific nearby venue and confirm its outdoor hours. Choose the actual seating position before comparing building shadows.
Summer evening light still meets obstacles
A long day does not ensure a late sunny table. The low evening sun may be blocked by buildings beside the waterfront. Check the whole visit interval, and distinguish a seat facing open water from one with a clear line toward the sun.
Winter needs a fresh comparison
The sun's lower winter path produces longer building shadows. A terrace that works well in June can be shaded at the same clock time in winter, and outdoor service may differ. Confirm the venue's current arrangements rather than relying on a summer listing.
Check wind and local covers too
Comfort on an open waterfront depends on more than direct sun. Review weather and inspect awnings, trees and shelter when you arrive. Those local obstacles and terrain are outside Coffee in the Sun's building-shadow model. Keep a nearby alternative that fits the conditions.
Try the building-shadow check before you leave
Open Coffee in the Sun, find your chosen spot and compare the estimated building shadows at arrival and departure. The free app includes today's timeline and three time jumps per day. The model uses mapped buildings, whose coverage and accuracy vary; it excludes trees, awnings and terrain, and cloud cover is not part of the shadow answer.
Use the five-step terrace check to interpret the result. Keep a nearby alternative and confirm the real seating on arrival.
