Daylight Hours Across the Pacific Time Zone

How latitude carves up Pacific Time daylight hours

Los Angeles sits at 34 degrees north. Vancouver sits at 49 degrees north. In between, the same clock governs 1,300 kilometres of coastline, but the sun obeys a different schedule in each city.

On 21 December 2026, Los Angeles gets 9 hours 53 minutes of daylight, with sunrise at 06:54 and sunset at 16:47. That is the baseline. Move north, and the winter day shrinks further. Move south toward San Diego and Tijuana, and it stretches out. The swing between the June solstice and the December solstice in Los Angeles is nearly 4.5 hours. At the zone's northern edge, the seasonal gap is wider still.

Why does the winter workday end in the dark in the north?

Finish work at 17:00 in Vancouver or Surrey in December and you leave under streetlights. Outdoor crews on construction sites lose usable light well before the closing whistle. Retail foot traffic drops once the sun goes. Restaurants seating dinner at 17:30 are serving in full night.

San Diego's December solstice gives more daylight than any other major city in the zone. That extra light changes commuting and evening recreation. People in San Diego are more likely to walk, jog, or eat outdoors in December than people in Vancouver. A chain with coffee shops in both cities sees different peak hours in January based on latitude alone.

The winter darkness is not uniform across the north. Portland gets slightly more December daylight than Seattle. San Francisco gets more than Portland. Each degree of latitude chips away at the afternoon.

How late does the sun stay up in Pacific Time summer?

Summer flips the script. On 21 June 2026, Los Angeles sunrise is 05:41 and sunset is 20:07, for 14 hours 26 minutes of daylight. The northern cities get more. Vancouver and Seattle see the longest summer days in the zone, with daylight stretching further into the evening than in Los Angeles or San Diego.

Those long evenings reshape the economy. Tourism extends later. Outdoor dining patios fill at 20:00. Evening events (concerts, farmers markets, sports leagues) start after 18:00 and run until natural darkness, which arrives latest in the north. Retail stores in tourist areas stay open later. The summer evening in Pacific Time is a commercial and social asset.

Does San Diego really get more winter daylight than Seattle?

Yes. The difference between the northern and southern edges of the zone is modest in summer. In winter, the gap widens into something that changes schedules.

A construction company with sites in both cities cannot use the same end-of-day schedule year-round. A landscaper in Seattle starts later and finishes before 16:00 in December. A crew in San Diego works a longer outdoor afternoon. The same latitude effect that gives Seattle longer summer evenings takes away its winter afternoons.

How DST reshapes Pacific Time daylight hours

Daylight Saving Time does not add daylight. It moves an hour of morning light to the evening. On Sunday 8 March 2026, clocks spring forward from 02:00 to 03:00. The sun rises later by the clock, but sets later too. That first week of evening light feels like a release after the winter dark.

The transition weeks cause disruption. Sleep researchers report an increase in traffic accidents and scheduling errors in the week after the spring shift. Employers who schedule outdoor work know the first Monday after the change feels like an hour of stolen sleep. The fall transition on Sunday 1 November 2026 returns the hour, but the dark commute returns with it in the north.

What Pacific Time daylight hours mean for work, sport, and shop tills

Daylight directly drives behaviour in four areas.

Outdoor work. Construction, agriculture, and landscaping crews start at dawn. In winter, that means a later start and a finish before 16:00 in the northern cities. In summer, crews can work past 20:00 and often split shifts to avoid midday heat.

Recreation. Hiking, cycling, and running peak in the evening in summer. In winter, recreation shifts to midday. Ski resorts in the mountains, which operate on Pacific Time, run on daylight, not clock time.

Retail. Summer evening hours generate more revenue for restaurants, bars, and attractions. Winter brings earlier closing times and lower foot traffic after 17:00.

Sport. West Coast live sports start early for East Coast audiences. The 10:00 PT NFL Sunday kickoff is a product of the zone's position. Evening games under summer daylight stretch the experience later for the home crowd.
