As a long-time San Diegan, I'm always amazed when people from not-here tell me we have no seasons.
For those of us who are used to living in a temperate zone of 65-75 degrees, popping down to the 40s is truly winter weather! The skies are gray, at night we sometimes get down to freezing - then everyone goes out in the evening to cover their flowers with tarps, as one plant or another is always in full bloom.
So what does winter mean when you live in the coastal southwest? That this is our rainy season - and wow! do we pray for rain as our droughts have driven us to strict guidelines on the use of water. Right now we can only water lawns 3 days a week and only after 6 pm. Driving through my neighborhood I see little banners up on the streetlights reminding us to conserve water. Winter (if we're lucky) means the ground gets un-parched, the reservoirs get a little back-up, and we get to remember how cozy it is to sit inside and watch the rain.
(My niece called her mom the other day saying everyone in her office stopped work to watch the rainstorm as it blew through her part of town. That's how rare it is to see "weather".)
Winter is also our time of deep red, bright red, almost black-red poinsettias - - - most of which are grown locally. There's nothing like a poinsettia to brighten up a gloomy winter afternoon, unless it's the crackling and warmth coming from the fireplace.
And did I mention snow? Yes, it snows in San Diego County - up on Mt. Laguna (see pic). And every year there's a trek to the mountains as San Diegans haul their kids up to see this weird white stuff that rarely makes it to town. (and yes, on a couple of occasions, it really did snow here in town).
Winter in San Diego - when we're lucky we get cold crisp air and clear blue skies. We all haul out what we call our "winter coats" and gloves . . . even though those of you who live in Minnesota probably compare our winter to a fine spring day. . . it really is a winter day here at home.
