To the best of our knowledge there is no weather station within Hidalgo, and the closest weather information can be found from the city of Monterrey less than one hour south.

Climbing Weather

Potrero Chico has a semi-arid climate that is known for extremely hot weather in the summer – reaching 35°C (95°F) or more for three consecutive months – and moderately cool temperatures in the winter. The average January high is 16°C (61°F) and the average low in January is 7°C (45 °F). The hottest month is August and the coolest is January. Temperatures and precipitation levels are ideal from November to May, but comfortable climbing is possible anytime of the year if the afternoon highs are avoided. Within Potrero Chico canyon there are always places to climb in the shade or sun, depending on which is desirable at the time.

The precipitation is fairly stable and usually mild. The only period of severe weather is during the rainy season months of September and October. Other times of the year there can be no rain for months at the time, ensuring great climbing each and every day. Temperatures, on the other hand, are very extreme and unstable, sometimes reaching 25°C (77°F) in January and February. Snow is very rare.

Additionally, the weather within Potrero Chico canyon itself is often better than the camping grounds immediately outside or the city of Hidalgo down the hill. Even when it is wet or raining outside the canyon, great and dry climbing can still be found inside.

Climbing Season
The best climbing season is in the winter when it is cool and dry, between the months of November and May. The rest of the year is generally too hot or rainy, though you can still climb in the mornings and evenings. The peak season is December, January, and February, when you will find many climbers enjoying the park.

    That plot drives me nuts! It needs two vertical axes — the temperatures are dwarfed by the rainfall in mm and I can’t see very precisely what the lows/highs for November are. Low of roughly… 10? 15? High of almost 30ish? Needs waaay more tick marks and needs to be much much bigger. Also, why not list the highs AND lows in the forecast? Will I need a sweater at night? How will I know what I’m getting into without precise temperature averages and current measurements?!?!?!?

    Thanks for nothing, BBC weather!!! even a raw data table would be better than that horrible visualization!! you should fire whatever artsy design student made that useless graph!

  • Please share a better image link and I’ll fix it 🙂

    Separate rainfall and temp graphs and label the high and low temps on the the new temp graph. The rainfall graph when combined with the temps changes the x axis scale so it is not at a level where you can read it for temps.

  • I didn’t make that graphic (don’t remember where it came from) but please suggest a new one 🙂
