The prickly pear is dying. Part of the problem maybe that a ground squirrel or other animal has burrowed under it and undermined it's root structure.

July 2013 Data Minus August 2013 Pictures

Life was busy in August. I was fortunate to travel to cooler places: Monterey, California and the Canadian Arctic and Greenland.

Here is the data for July.

July brought some much-needed relief with cooler daytime temperatures and some of the monsoon moisture reached the city. The average high temperature was 99°F (37.2°C), which was 0.70°F (0.39°C) below normal. We didn’t receive as much nighttime cooling as the average low was 76.9°F (2.50°C). The official rainfall was 2.60” (66.04mm), 0.35” (8.89mm) above normal. My house received much less at 1.32” (33.53mm).

Enjoy some of my pictures from the Arctic.

July 2013 Pictures June 2013 Data

June temperatures made up for what May was missing, 100°F (37.8°C) temperatures. Every single day in June recorded triple digit temperatures to make it the HOTTEST June on record. Notice how there are now new categories on the data table that include 105°F (40.6°C) and 110°F (43.3°C) + highs.

  I’ve lived in Tucson most of my life. Once the temperature reaches above the 105°F (40.6°C) mark, it definitely seems hot. That is the point where I switch my brain to Celsius, since mentally it doesn’t seem as bad when it is only in the 40’s. I did this most of the month since there were 18 days over that mark this month.

 

June’s average high temperature was 105.4°F (40.8°C), this was 5.10°F (2.83°C) above normal. Rainfall was non-existent at my house, but the official site received 0.03” (0.24mm).

The prickly pear is looking parched and ocotillo is void of leaves. Note how the saguaro has bloomed since last month's pictures.

May eluded the milestone 100°F (37.8°C) day. The legend states that this is the day that the ice breaks on the Santa Cruz River. Since the Santa Cruz River never has ice, this is more of a milestone in terms of television news contests for the viewers. Prizes range from cruises to Alaska to air conditioner servicing. Normally, Tucson records 4 days at or above the century degree mark in May. 

Overall May was warmer than normal. The average temperature of 69.8°F (21.0°C) was 2.8°F (1.56°C) above normal. Rainfall was miniscule at both the official site and my home at 0.01” (0.25mm). This continues the yearly deficit and adds to the drought conditions.

May 2013 Pictures and April 2013 Data

April 2013 tied with April 2012 as the 10^th warmest on record. When the last 3 April’s temperatures are combined, 2011-2013 was the 3^rd warmest on record. The highest recorded temperature for the month was 97°F (36.1°C). With only 0.12” (3.05mm) of rain at the official location, drought conditions were elevated to a serious level.

The saguaro displayed buds at the beginning of April. The prickly pear displayed beautiful yellow blossoms.

The spring brings wonderful color to the desert with blooming cactus. These blooms eventually become fruit providing food for the wildlife. Even my struggling prickly pear is showing buds.

March 2013 proved to be the second warmest and ninth driest on record. This was in contrast to a cooler than normal January and February. The highest recorded temperature for the month was 94°F (34.4°C). The average high temperature for the month was 6.80°F (3.78°C) above normal at 80.9°F (27.17°C). The average low temperatures were also above normal which resulted a higher than normal overall average temperature for the month. Rainfall was virtually non-existent at the official location at 0.01” (0.25mm). At my house we received a bit more at 0.15” (3.81mm). Officially our rainfall was recorded at a deficit of 0.72” (18.29mm).
