Puno weather in short
Puno lies at about 3,800 m on the shore of Lake Titicaca. Days are cool and nights are cold in every month. What changes through the year is the rain. From December to March, much more rain falls than from May to August. July is the driest month in the table and January the wettest. Frost is likely on winter nights.
The figures below are long-term monthly normals that Peru's weather service SENAMHI publishes for Puno. They describe the typical climate, not a forecast for a certain date, and the table comes from an older publication, so treat it as a climate profile and not as measurements for 2026. Highs and lows are monthly averages, not records. Check a current forecast a few days before you travel.

Best time to visit Puno
There is no single answer, because two recommendations exist.
| Goal | When | Good to know |
|---|---|---|
| Overnight on Amantani | April to October | The national tourism board recommends these months. It is a recommendation and not a closure in other months |
| Driest weather | April to August | A tourism board article on community tourism describes the dry season this way. The monthly table shows July as the driest |
| Candelaria festival | February | Falls in the rainy season. See the Candelaria page |
| Warmer days | October to December | Highest daily highs of the year, with rain returning |
The table cannot predict a given week. Nights are milder in the wet months than in the dry winter, and the coldest nights come in the dry season.
What to pack
Practical advice that follows from the numbers.
Layers for cold nights
Average lows are around 5 °C (41 °F) from December to March and fall to about freezing or below from May to August. Pack a warm layer, a hat and gloves, especially for a night on an island.
Rain gear from December to March
These months bring 87 to 174 mm of rain per month on average. A rain jacket matters more than an umbrella on a boat.
Check before a boat day
Conditions can change, so ask the operator on the morning of your trip. See lake tours from Puno.
Altitude
Puno lies at about 3,800 m. General health advice is to keep the first 48 hours light. Read the altitude page.
