When and what to plant in Tlaxcala?

Hi, Im staring to clean a piece of land at my motherīs house, Iīm planning to plant there.

I have been reading from some websites and a couple of books on what to plant and when, but most of the information is made for other climates (US or UK), I live in Tlaxcala, Central Mexico. THe climate here is a lot less cold than in the US r the UK. We will start having frosts in november or late october, and the last frosts are usually in February.

Though the frosts are not very low temperatures, maybe just a couple of degrees under 0 Cecius (32 farenheit), probably -3C (26 farenheit) at the most.

I would really appreciate it if someone could tell me what can I plant under these weather conditions.

I also read about "cold frames", I would think of building one if this would broaden my possibilities significantly.

Thanks everyone for building a great community!
 

Ok, so Iīve been doing my homework:

August and September are usually rainy (about 100mm each month). After that, there is little rain.

Temperatures are about:

August: from 10  to 30 celcius degrees (50 to 86 F)

September and October: 3 to 25 celcius degrees (36 to 77 F)

November and December: -1 to 25 celcius degrees (30 to 77 F)

Runner beans should do well I think 

I thought there might be enough of the season when it was not too chilly
