Sunrise and daylight in Juana Díaz

Sunrise in Juana Díaz occurs in the east, but its exact clock time changes gradually through the year. Sunset shifts as well. Puerto Rico’s tropical latitude limits the dramatic seasonal contrast found much farther north, yet mornings and evenings are not identical from month to month.

The municipality’s southern position and local horizon can affect how sunrise appears from a particular location. Hills, buildings, trees, and cloud cover may hide the Sun briefly after the calculated sunrise time. An astronomical listing describes when the Sun reaches the horizon, not necessarily when direct light reaches every street or valley.

Use the date for which you need sunrise information. Confirm that the location is Juana Díaz, Puerto Rico. Read the result in Atlantic Standard Time. Allow for terrain, weather, and an obstructed horizon when planning outdoor activity.

For photography, walking, farming, or an early departure, check the daily sunrise rather than relying on a remembered time from another season. Civil twilight begins before sunrise, so useful outdoor light may arrive while the Sun remains below the horizon.
