When should I hike Santa Cruz?

The best time to hike is the May through September dry season.

Many local guides told us the best months were May & June — lovely weather & less crowded than July & August. October is possible, but it will likely be overcast & snow is likely.

Should I hike off-season?

There is no one to stop you trying any month.

In the wet season, snow on Punta Union may force you to turn back.

Avoid February & March, normally the wettest months.

What is the weather like?

Gladly the Cordillera Blanca enjoys probably the best high mountain weather in the world. May through September hikers get weeks of clear skies at a time. Whoo hoo!

The highest peaks hold the clouds, especially in the afternoons, disappointing photographers.

Several locals told us that the weather had been less predictable in recent years, perhaps the result of global warming.

Being close to the equator, the temperature is fairly stable year round. The hiking season in the central Andes is actually during the South American winter — only because this is the dry season in the Andes.

Bring clothing good to -10°C to be on the safe side. Certainly you will have mornings well below freezing. We wore 6 layers at times.

We recommend you rent a down coat in Peru if you are unsure you have warm enough clothing. It is light weight & makes a great pillow.
