The Summer Monsoon

Monsoon has its roots in the Arabic language and it refers to a seasonal shift in the wind. In the American Southwest, toward the end of June or early in July, the prevailing westerly winds shift to southerly ones, bringing tropical moisture up from Mexico. Dew points climb. Mornings dawn with unusual mildness and the sun rises through screens of vapor over the mountains:

Even on mornings that start off in golden clarity, it won’t be long before the powerful sun begins to boil the atmosphere:

Before you know it, an unexpected rumble of thunder fills the air and the breath of rain-cooled air sweeps over the city.

Most of these summer thundershowers are brief and only last 20 minutes or so. That’s just enough time to dodge under a welcoming portal and enjoy a respite from the sun. They are notorious for erupting right as the Santa Fe Opera lights its spacious stage for an opening. Many a production has been enhanced by the sturm und drang of a flaring late evening storm over the western mountains. Everyone comes to love them because of the way they cool down the evening to perfect sleeping weather. The afternoon sky is full of drama:

Of course, too much of a good thing is not always wonderful. You could be walking your dog in the arroyo one moment:

And the next running for the hills:

This is a legitimate natural hazard, and one which you must be aware of in the summer when you are visiting our part of the country. Lightning is another danger, as is hypothermia, for those hikers that are enjoying a walk high in the mountains. Someone is struck and killed by lightning up in the highlands nearly every year.

So don’t forget to tuck in a travel umbrella when you come to visit us this summer. Bring a sweater if you’re planning to attend the Opera: that rain-chilled air is cooler than you probably expected. And keep you eyes open for rainbows – our summer sky is festooned with them:
