A couple of days ago I made a quick trip to Spokane, Washington, on some family business. As I’m writing this in mid-December, just short of the winter solstice (shortest day of the year), I was struck by how early the sun set and then, the following morning, how late it rose again. It seemed like I’d “lost” an hour of daylight.
Upon returning home to the San Jose and Los Gatos area (Silicon Valley), I found an awesome site that charts sunrise and sunset (dawn and dusk) times for all of the world. The link below will take you to the page for San Jose, California, which is a good representation of Santa Clara County and the general Silicon Valley area.
I played with this site awhile, checking the hours of daylight for today going north and south of this area. It will be the same amount of daylight hours (or very close) during the shortest daylight day of the year, December 21st. So for people moving around on the west coast, here’s a comparative glimpse on the number of daylight hours during these shortest days of the year:
In summer, of course, it’s the opposite. The further north you go, the longer the days, while the closer to the equator, the shorter the days (and the smaller the swing between summer and winter).
During these “shortest days of the year“, a later sunrise and earlier sunset are really noticed. In Spokane (about the same as Seattle) the sun is coming up at 7:33 and setting at 3:59pm vs the San Jose area’s 7:16 sunrise and 4:52 sunset (8:26 hours of sun up north vs 9:36 in the south Bay Area – 1 hour, 10 minutes more sun here).
How does this compare to other major cities around the US? How many hours of sun are they all getting during these darkest days?
New York City 9:13
San Jose 9:36
Los Angeles 9:53
San Diego 10
Seeing the wide differences in sunlight hours alone, I can see why “snowbirds” would migrate south in winter!
Another factor to consider is how much sun you actually see during those hours of daylight! The San Jose area gets only about 20″ of rain during most years. Most of our rain comes between November and March or April, but even so, it’s unusual to get rain day after day for more than 3-5 days. Normally there are sunny and dry days inbetween patches of overcast, drizzle or rain. The weather will be drier in south county or in the east valley and wetter closer to the coastal foothills (Almaden Valley, Los Gatos, Los Altos). The Santa Cruz Mountains usually hold back the summer fog, leaving the inland areas sunnier and drier than the coast.
Sometimes the winter fog is “ground fog”, or fog from the Pacific which snakes its way inland through the Golden Gate and inches down the bay southward. When that happens, you can sometimes go to the top of the Santa Cruz Mountains and enjoy the sunshine while hiking the trails off Skyline Boulevard.
We have 300 sunny days per year in our mild, subtropical climate. Not bad! Even our winters are not so tough. As one of my Finnish clients said to me recently, “Mary, you don’t really have winter in San Jose!”
Silicon Valley residents will sometimes refer to “South County”. Where is it? This is the area south of south San Jose where you find Gilroy, Morgan Hill, San Martin and nearby areas.
The south county region of Santa Clara County is the last real stronghold of agricultural land in the valley (that plus the eastern range by Mt Hamilton). There you will find many orchards, vineyards, farms and ranches even today. As you drive through Gilroy you may catch a scent of garlic – particularly if you drive highway 152 toward Pacheco Pass as you go past a garlic processing plant! In summer you will want to visit the famous “Garlic Festival” at least once, if not make it an annual event.
South County is home to the discount Outlet Malls in Gilroy (at Hwy 101 at 152 east), so if you live in or near San Jose, you will eventually find your way there!
Want to relocate to South County? Many San Jose area residents consider it a good place to retire since they can downsize to a comfortable home and often pay much less than a comparable home might cost in Los Altos, Saratoga, Los Gatos, Willow Glen or Almaden and at the same time get more home. A number of my clients have spoken of wanting to retire into the Eagle Ridge Golf Course area of Gilroy for that very reason.
