Tuesday, November 30th
Blue skies with small cumies. Looked like good XC weather.

-------------------
Monday, November 29th
Like the prior two days the skies were hazy throughout the day, but not so much, and the cumies in the slightly hazy sky had good form. It was definitely soarable and I will go out on a limb to say that there was XC potential.

-------------------
Sunday, November 28th
Like yesterday the skies were overcast all morning and changed to cumies in haze by midday, to overdeveloped in the late afternoon. Definitely soarable, but maybe not the best for XC.

I missed the ride up to launch with Daniel Pedraza and had to take care of other business at noon, but Alfredo Carsolio caught that ride. He reported later that he climbed quickly up to 600 meters over launch and flew to Tenancingo. He said that he cut his flight short only because he was short on time, but could have flown much longer.

-------------------
Saturday, November 27th
There was a rather dense high cloud layer in the morning giving way to cumies in haze in the afternoon. I got a ride up with Daniel Pedraza. There were mild cycles at launch, and a weak easterly which was not enough to mess with the thermals at launch, but just enough to make the wind directions switchy down in the valley.

I launched at 2pm on the Nova Mamboo that Alfredo Carsolio loaned me. It still has a 80kg minumum which is too big for me, but when I flew it with ballast at least it wasn't flying at stall, but I was flying cautiously on it this second flight. I climbed up rather quickly in mild but steady thermal columns. At 2560 meters I sort of topped out and bailed for the Tenancingo side. I made some passes around Ixpuichiapan where I would normally find some good thermals, but not this time. I sunk out quickly and did not even make it to the Insurgentes LZ, but landed in the soccer field next to the old prison that never existed (walls started and project abandoned many years ago), for a 12 minute flight.

It is an excellent quiet and manicured LZ area and is only a "block" from the insurgentes LZ as the crow flys, except it sucks because it is on the other side of two small rivers, and you have to walk a long way around to get out of there, and then take a taxi to get back to town.

I heard that Alfredo Carsolio flew later in the day and had a good flight.

It was soarable but not the best for XC flying. It should have been a good day for El Picacho given the conditions.

-------------------
Friday, November 26th
A simi-transparent cirrus high cloud layer formed around noon and thickened towards late afternoon. It still looked soarable, but most likely not much for XC.

-------------------
Thursday, November 25th
Early in the day there were blue skies, and then little cumies forming around midday, and in the afternoon areas to the north with about 50% cloud/blue sky density, with areas to the south more open. Looked like there was some long distance XC potential along easterly or westerly routes, and a generally awesome day if one were to fly.

-------------------
Wednesday, November 24th
It looked like it must have been great soaring at all sites, but with no cumies to mark the thermals, I won't rate it as a great XC day, unless you already know where the house thermals are at. All the townspeople ask when pilots are going to arrive from Canada. I tell them that they come here when they get tired of building snow-men.

-------------------
Tuesday, November 23rd
Blue skies with little cumies to mark out the thermals. Excellent XC conditions it appeared.

-------------------
Monday, November 22nd
Blue skies with little cumies to mark out the thermals. Excellent XC conditions it appeared.

-------------------
Sunday, November 21st
Blue skies with little cumies to mark out the thermals, and bigger cloud streets over in Malinalco and beyond. Excellent XC conditions it appeared. Daniel Pedraza was not driving up and no other pilots were flying, so I opted not to fly since my previous back injury would have been strained by too much hiking with the pack.

-------------------
Saturday, November 20th
Blue skies with little clouds, but this time they were higher (mid?) level clouds, perhaps not so directly related to thermals down low. Still looked pretty good, like there was XC potential.

-------------------
Friday, November 19th
Blue skies with puff ball cumies forming little cloud streets and a drift towards the Malinalco valley. Looked like a great XC day.

-------------------
Thursday, November 18th
Clear blue skies but no small or large cumies to mark out thermals. Definitely soarable.

-------------------
Wednesday, November 17th
Blue skies with puff ball cumies forming little cloud streets. Looked like XC heaven.

-------------------
Tuesday, November 16th
With clear blue skies and little puff ball cumies to mark out all the thermals it looked like excellent XC conditions.

-------------------
Monday, November 15th
With clear blue skies and little puff ball cumies to mark out all the thermals it looked like excellent XC conditions.

Sunday, November 14th
Cumies developed early. Alfredo was so kind as to take me flying at El Picacho Malinalco, and loan me his Nova Mamboo size small, possibly for a few weeks until I can get another wing. The thing is that the minimum weight on the small mamboo is the same as the medium force, 80kg, and I only weigh 61kg. Anyhow we kited a lot and flew various round trips doing top landings at the Terrazas. I got tossed around kind of rough in some of the Picacho thermals. The Mamboo displayed nice ground handling properties. I'll have to try it in La Malinche thermals to see if I want to fly it more.
There was the same rather dense cumi cloud cover along with haze in the Malinalco valley, but the thermals were rather strong considering, and I saw a number of the usual pilots there, top landing and final sleds late in the day. Daniel Pedraza was at the la Malinche launch with some non-pilots and said that conditions looked good. It might have been good XC conditions.

Here is a video of Alvaro Cartin top landing at the Terrazas, El Picacho, Malinalco.


-------------------
Saturday, November 13th
Cumies developed early. I called Alfredo Carsolio at noon when he was on launch and he said that the thermal cycles were too strong and he probably wasn't going to fly. In the afternoon it was clearly overdeveloped. Possibly soarable earlier at La Malinche, and possibly better conditions for flying at El Picacho, Malinalco.

-------------------
Friday, November 12th
Clear blue skies with just a few cumies to mark out the thermals. Soarable with XC potential.

-------------------
Thursday, November 11th
Clear blue skies with just a few cumies to mark out the thermals. Soarable with XC potential.

-------------------
Wednesday, November 10th
A cold night but not quite so cold, and in the day clear blue skies, a little warmer, and a few cumies formed. Soarable with XC potential.

-------------------
Tuesday, November 9th
Same really cold night and chilly day with clear blue skies, but late in the day a convergence ridge formed to the south, indicating that the mass of cold stable air is breaking up. Soarable but not the best for XC.

-------------------
Monday, November 8th
Same really cold night and chilly day with clear blue skies. Soarable but not the best for XC.

-------------------
Sunday, November 7th
Today was like the previous four days with clear blue skies, cold nights, cool days, and no cumies. In the afternoon I flew La Malinche with Gerardo and Hector of Ixtapan, Henry Morgan who brought his cousin from Pasadena who he flew tandem, and Alfredo Carsolio. Thermals were not well developed but punchy given their small size. Hector flew to Tenancingo, Morgan and his cousin flew to the cabaƱas LZ, and Alfredo and I landed in a field by the the Zumpauacan highway. My wing felt unstable as always, practically stalling if pulling on either brake, and I vowed to not fly until I get a smaller wing. The cool thing is that Alfredo offered to loan me a smaller wing until Bob brings me one. Maybe I will be able to fly in the competition in December after all. Soarable at La Malinche and Mali, but not good XC conditions.

-------------------
Saturday, November 6th
I expect that it was soarable at La Malinche and Mali, but there were no cumies to mark out the thermals. Henry Morgan swung by late in the afternoon to head up to launch with D. Pedraza.

-------------------
Friday, November 5th
Must have been soarable at La Malinche and Mali, but blue thermals, no cumies, so I won't call it as XC potential. It's been getting coooold at nights, like near freezing.

-------------------
Thursday, November 4th
We had an exceptionally cold night which clear skies throughout the morning, and strong winds gusting from the north, staying pretty cold throughout the day. Not flyable.

-------------------
Wednesday, November 3rd
Blue skies and cumies forming early, and it was seriously overdeveloped by noon, and raining by 2pm. I would rate it as not soarable for La Malinche or Mali, but perhaps suitable training conditions at Mali early on.

-------------------
Tuesday, November 2nd
Beautiful small high altitude cumies most of the day to mark out the thermals. Overdevelopment around 3pm, but in an hour it resumed to nicely formed cumies. Good soaring with XC potential.

-------------------
Monday, November 1st
It looked like an excellent day for soaring at all sites with definite XC potential.
