Being at latitude 18.49 north (give or take a few miles) we're about 300 miles south of the Tropic of Cancer and 1100 miles north of the equator. So, as the earth rotates through the seasons (that is, around the sun not on its axis), the apparent path of the sun moves from south to north and back again. The sun was at the Tropic of Capricorn last December 21st (we in the northern hemisphere call it the Winter Solstice), crossed the equator on March 20th (the Spring or Vernal Equinox - day/night about equal duration) on to the Tropic of Cancer which we called the Summer Solstice on June 21st, and is now on its return trip towards the equator to be there on September 22nd for the Fall or Autumnal Equinox.
So, those of us between the two Tropics located at 23.5 south and north latitude, we will have the sun overhead twice a year. Once between March and June and again between June and September.
A neat way to see how the sun's apparent path changes is at SUNCALC where you can visualize path of the sun, sunrise, sun peak, and sunset. The easy to use program displays azimuth, altitude, shadow length for each location, date, and time of day past, present or future anywhere in the world.
The front of the house - and there only is a front as we're blocked on the other three sides - faces due north. During the summer we can follow the shadows as the sun's apparent path moves south to north and back again. We get a reprieve from September to March as the sun is on the other, hidden side of the house that half of the year and so the shadows in the yard are longer and we don't bake quite as much.
Despite the high walls you see in the picture, we do get a breeze thanks to some very well placed trees on two sides. The prevailing breeze is from the east - the Easterlies or Trade Winds as they're known. It not full force which is fine as that would get tiresome but it's enough of a breeze that being outdoors all day isn't a hardship.
Inflation has driven a lot of prices higher this year. Today, a kilogram of green poblano chiles costs 29 pesos (US$1.66), up 55% on their 2012 price of just over 18 pesos. Beef is up by just over 50% to 128 pesos per kilogram (US$3.32/lb) for the least expensive cuts, cream has risen by a similar percentage while pomegranate (a red-coloured fruit) has spiked by an exorbitant 242% from 18 pesos per kilogram to 63. Crazy. Walnuts jumped from 306 pesos per kilo in 2012 to around 800 today, a 161% increase.
I mention these items because next month is the celebration of Mexican independence and these items are used in a well-known, much-loved recipe called Chiles En Nogada whose colours (Green, White, and Red) are the same as Mexico's flag. The dish in restaurants will now cost anywhere from 200 to 400+ pesos or, if being made at home 1200 (US$68.57) to 1500 pesos (US$85.71) for 6 people. Keep in mind the minimum wage is still but 80 pesos per day (US$4.57).
