Puno & Lake Titicaca Climate
Puno's elevation is about 3,822m gives it of course a harsh mountain climate. The elevation make that the sun during the day is quite strong and hot and that you should at all times be protected against the sun during the day. Especially in the top of the dry season (which is also the high season for tourism- July / August) you must make sure to be well protected. The days are without clouds and you will probably spend quite some time walking and sailing on a boat. In the wet season, the days are not necessarily as wet as in Cusco but you can have quite the shower now and then. These will mainly fall at night but in January and February the weather is very unpredictable. Another factor to keep in mind is the wind. Located at a bay of the lake, with mountains on the other side, the winds coming from the lake can have quite some effect on the temperatures in Puno. In the evening when the sun goes down, the temperatures drop significantly and can easily go below 0°C. Finally, it is necessary to keep the altitude in mind, whatever you do in Puno. Its location over 3800 meters make every activity much harder and you will be surprised of the number of times you will have to catch your breath the first couple of days on this altitude.
