Film production in Cardiff
Between June and December, usable daylight in Cardiff moves by 8h 44min — from 16h 36min down to 7h 52min. An exterior day in December is a different day from one in June. This page carries sunrise, sunset and golden-hour times for all twelve months, the climate profile and the local production landscape.
Light and shooting hours
On 15 June, the sun in Cardiff rises at 04:56 and sets at 21:32; the evening golden hour starts at 20:38 and runs for 54 minutes. By December that shifts to 08:12–16:05, with a 61-minute golden-hour window from 15:04.
For scheduling, that means the window for the one shot that lives on light runs between 44 and 61 minutes across the year. Put it last in the day and the first overrun takes it.

Blue hour and shooting windows
Blue hour in Cardiff starts at 22:00 in June and ends at 22:20 — a window of 19 minutes. In December it is 15 minutes from 16:30. If you need a city view with lit windows, that window is all you get.
Sunset moves fastest around the equinoxes: between March (18:17) and September (19:30) there are 73 minutes of difference. A schedule running over several weeks cannot work from one fixed "sunset" time.
Weather and washout risk
Cardiff averages 18 rain days in December and 11 in April. A three-day exterior shoot in December statistically loses 1.8 days — not a forecast, but the basis for deciding whether a cover set belongs in the budget.

Production landscape
Our production database holds 1 companies in Cardiff with verified film or video production activity. That is not an industry estimate but the count of vetted records — an entry is only kept when at least two citable production credits back it up.
Planning a shoot here
A schedule that ignores these numbers looks fine on paper and falls over on the day. TillyGen folds sun position, travel and crew availability straight into the schedule — if the exterior no longer fits before sunset in December, the plan says so, not the wrap report.
