Fully overcast conditions produce flat, diffused light that is good for portraits but lacks the dramatic quality of golden hour. Partly cloudy skies create the most dramatic conditions.

About This Monthly Sunrise Data

All sunrise and sunset times in this September table for Christchurch are calculated using Jean Meeus astronomical algorithms, implemented via the SunCalc library. Calculations use the coordinates of Christchurch (-43.5321°, 172.6362°) and the local timezone (Pacific/Auckland). Times are accurate to within 1 minute and account for atmospheric refraction.

The times shown are for the center of the sun crossing the horizon. Sunrise is defined as the moment when the upper limb of the sun first appears above the mathematical horizon. Sunset is when the upper limb disappears below the horizon. Both definitions account for atmospheric refraction, which lifts the apparent position of the sun by approximately 0.5 to 1 degree near the horizon.
