September 2011 Summary
Days of possible Good XC or better Tandem Conditions from La Malinche – days
Days of possible Soarable Conditions from La Malinche, including the above XC days. – 11days
Non-Soarable days from La Malinche – 19 days
(Once in a while I might mark a single day as both Soarable and Non-Soarable, like when part of the afternoon is soarable, and the other part is not.)
---------------------
Monday the 19th through Friday the 30th
I would guess that about half of these twelve days were soarable, and half were not. Although there was not much midday storm activity, the ground is still most, and most days were easterly and some northerly action too. However as you may know we had about a week of solar storm activities with rather higher radiation levels hitting the earth at times, and I stayed indoors more for that too. http://www.swpc.noaa.gov/alerts/warnings_timeline.html

Saturday the 17th and Sunday the 18th
These days had generally clear blue skies with nice thermal induced cumies. There was an east wind, but it was not very strong, leading me to believe that La Malinche was soarable, but tricky with east winds and still moist soil.
---------------------
Monday the 12th through Friday the 16th
Monday generally had blue skies with small nicely formed cumies. Monday looked like good soaring potential. Tuesday and Wednesday looked possibly not flyable due to more overcast skies and easterly and northerly wind directions (but possibly still soarable). Thursday and Friday looked very good for soaring conditions. I hear that Hector in Ixtapan had a good flight on Thursday.
We had little precipitation these days, just a little at night on a few nights. I would be hesitant to call for good XC weather yet, since the area is still moist, but from the point of view from the ground we had some good days, and it looks like we are indeed leaving the rainy season. There is also the question of getting more southerly winds rather than easterly and northerly.
---------------------
Monday through Sunday, the 5th through the 11th
All days were non-flyable due to wind directions from the north and east. Thursday night was the first night of the season where the skies were clear, and it was cold. Also coinciding with the clear skies that night and the next day was a major solar storm. On Friday the skies were clear too, but winds were from the NE so it was not flyable for La Malinche. The solar storm cause power waves in the electrical system, and I could correspond that real-time on the web watching the solar wind. On Sunday, at the hour that the phase of the solar storm abated, the clouds came back again, and it rained later.
Aside from the solar activity, the locals marked Friday as the change in seasons, where things will gradually dry out and by late October and November the strong thermals and southerly wind direction should be back again. I expect a little more rain this month too.
---------------------
Thursday through Sunday, the 1st through 4th
All four days overcast, rainy and east all day and not flyable.
