*and the Greater Phoenix area. For specific information on weather
in the Tucson area and the Phoenix area see the National Weather Service
site. Hot weather in the southwestern deserts has two phases - a hot dry spring that
feels like summer and usually lasts until approximately June 15 when the "wet
summer" or "monsoon" begins in Southern Arizona and lasts until
approximately August 16.
What's Blooming: Over
the next 3 months (particularly June and July), there is much less pollen in the air than
there was in the spring. Most of the pollen is from grass, mainly Bermuda
grass. Some pollen from Hackberry and Privet may appear in July. After the
summer rain has started, weeds including Amaranths (Pigweeds) begin to grow, flower, and
release pollen. Plants that contribute to the pollen count through Summer, in order
of prevalence are:
Pigweeds/Russian Thistle, Saltbush
- Atmospheric mold counts remain low until the monsoon is well advanced in early August.
The counts continue to rise through the end of summer and early fall, but do not
reach levels seen in the midwest or southern states.
- Atmospheric ozone levels increase in the summer. Particulate levels become very
high during summer wind storms and blowing dust.
- Evaporative cooling increases indoor humidity as monsoon weather approaches, favoring
growth of indoor mold and proliferation of house dust mites.
- Allergic rhinitis is less severe in the summer, due to low pollen counts.
- Asthma also tends to improve for the same reason and because of low prevalence of mold
and fewer viral respiratory infections. Soon after children go back to school in
early September, viral respiratory infections begin and the incidence of asthma attacks
- Take your prescribed medications.
- Fertilize and water Bermuda grass lawns liberally. Cut the lawn once a week.
Alternatively, kill your
Bermuda grass lawn and install desert landscaping - summer is the best time to do
this. The Arizona Cooperative Extension Master Gardener program can also advise
on removal of weeds that grow during the monsoon, an important task for those with pollen
allergy. Phone numbers: Tucson (520) 626-5161, Phoenix (602) 470-8086 ext 323).
- Stay indoors during windy weather and in the afternoons of air pollution alert days
(usually from ozone).
- Change pads and water once a month during evaporative cooler operation. Consider
installing an automatic water changing system. If your cooler has a single 4 or 6
inch thick pad, the pad does not need to be changed more often than recommended by the
- If you have refrigerated air conditioning, consider obtaining an air purifier with
a HEPA filter for the bedroom.
- If you will be out of town for 2 weeks or more and are on
allergy injection treatment, inform your allergist in advance to arrange for dose
adjustments or, in the case of a long vacation, for injections at your destination.
- If you have asthma, be sure to take full inhaler canisters with you.
Most patients with moderate or severe persistent asthma will need to take an
emergency supply of prednisone tablets with them. Ask your doctor about
- Anticipate the asthma season that starts when children return
to school - be ahead of the curve! If inhaled
antiinflammatory preventive medicines (inhaled steroids) have been prescribed but have
been discontinued because of seasonal improvement, be sure that they are taken again regularly from August 1st onwards.

Exposure to Allergens in the Home.
