The Southwestern Monsoon
Our blog has been quiet for the last several months for a variety of reasons, but mostly due to the arrival of warmer weather and a shift to outdoor work. There are always a multitude of things that need fixing or maintenance, the vegetable garden needs tending along with what has been the major project of the summer â€“ the remodeling of the original straw bale cottage that we built back in 1990. Most of my past blog posts during the winter were largely image driven and since I havenâ€™t spent much time with the camera, some of my motivation has been missing. This past winter Mexico was great in that we had nothing else to do, but absorb the contrast we were experiencing to life here in the States. The intensity and passion of life there provide constant opportunities for good photographs.
However, I got somewhat of a wake-up call recently from readers complaining about the lack of posts to the blog. So what else to do, but write something. Otherwise I’d be overtaken by guilt and the pressure to accomplish something. So here begins an account of some of what weâ€™ve been up to here at home.
Southeastern Arizona, spring through early summer, is a period of waiting for rain. Itâ€™s a time of contrast, the cottonwoods and other local trees, burst forth with vibrant green leaves as the overall landscape becomes increasingly dry. In what amounts to somewhat of a reverse autumn, the leaves of the local oaks turn orange and yellow, drop their leaves and provided it has been a winter of average moisture, immediately sprout new green leaves.

The sky, normally a rich deep blue, fades and desaturates. We repeatedly comment to one another how gray everything appears.

The heat steadily increases, typically reaching its summer peak during the month of June. The humidity drops steadily to what feels like a negative value.

In the midst of this somewhat harsh landscape, many of the local plants, notably the cactae and agave families, attempt a balancing act with displays of brightly colored flowers.

Spring bird arrivals contribute as well – Vermilion Flycatchers, Orioles and Scarlet Tanagers. It’s a fascinating time as well for wild edible plants, but more on that in another post.
By the end of June, itâ€™s easy to get the feeling that itâ€™s never going to rain again and that the summer will be a bust when it comes to moisture. Although common sense dictates otherwise, there comes a point when one is absolutely convinced that it will not rain. Even the wisest succumb to this temptation.
It is this heating and drying that coaxes the jet stream gradually northward and in turn, the winds shift to a more southerly direction bringing humid air from the Sea of Cortez and the Gulf of Mexico. Large cumulonimbus clouds (thunderheads) appear as the humid air combines with the summer heat, signaling the beginning of what is called the â€œmonsoon season.â€ During that period we can receive up to as much as 50% of our annual rainfall. These rains, â€œlas aguas,â€ as they called in Mexico, ultimately arrive and relieve the tension that has been building for months in the landscape, people, plants and animals. June 24th, San Juanâ€™s Day, is considered by many to be the beginning of the summer monsoon season, but my experience suggests that this date applies to the region further south in Mexico, For the most part, the 4th of July seems a more realistic date.

In this part of the world where water is scarce, especially true for those who are closely tied to agriculture, the monsoon rains are a critical life event. Good monsoon rains are reasons for celebration. They make people happy, possibly ecstatic, bringing prosperity and health instead of depression, famine and sometimes death. Whether one is religious or not, everyone knows that they are â€œgifts of the gods.â€ When they are late, even the non-religious can be found praying and making offerings.

The monsoon arrival takes many forms, sometimes it struggles and stutters, sometimes with a furious downpours that last for weeks on end. This year, through the early part of July, the monsoon stuttered with occasional brief showers that typically bring little more than frustration and fear that the monsoon will amount to little more. It is only when the fury of a fierce downpour happens that oneâ€™s confidence is restored in the goodness of the universe. However, it is essential that the first downpour be followed relatively soon by another, otherwise doubt and depression can easily return.
Once the rains start, we rarely irrigate the garden the months of July, August.
Rainfall amounts for the two month monsoon season of July and August vary, some years more than others. In my 25 years in Canelo, the worst year I can remember totaled 6 inches for the two months and over 20 inches for some of the better seasons.

From the early signs, it looks like this year might be somewhere in between. Weâ€™ve had two heavy downpours and numerous light showers. The grass is turning green, most days are overcast, the dew point is hovering around 60, humidity ranges from 50 to 75% and the temperatures have settled back down into the 80s where they will most likely stay until September. To say the very least, itâ€™s an amazingly comfortable and beautiful time of year, just about as close to perfect as one can get.

What a beautiful illustrated essay. Fills me with nostalgia. Sally Hale
Nice to hear from you, wish you were here.
Worth waiting for! Beautiful shots, Bill. The huachua's stalk was just about5' high during the plaster workshop in April, so it's great to see it flowering so tall.
With the advent of internet-accessible weather monitoring, the anxiety associated with waiting for the monsoons to come to life can afflict even those of us stuck somewhere other than Santa Cruz, Co. It's a little ridiculous how much I, from my parched corner of Oregon, enjoy seeing the rains arrive in SE Arizona.
You guys should be getting a parcel soon with some necessary supplies for monitoring the hummingbird blitz that's going to start in your neck of the woods early- to mid-August….
