Stay informed about the current weather conditions in the city of Osorno. Below you will find the most up-to-date information, including detailed forecasts and visual charts that will help you plan your journey.

The climate in Osorno can be described as temperate maritime with a significant oceanic influence. There is no sweltering heat or extreme frost here, and the temperature regime remains quite mild throughout the year. Travellers should expect a clear division into seasons, each possessing its own unique character and atmosphere.

Summer, which lasts from December to February in Chile, delights visitors with pleasant warmth and is the driest period of the year. The average daytime temperature comfortably holds in the range of +21…+23°C, which is ideal for long walks and sightseeing. Winter (June–August), by contrast, is cool and humid: the thermometer often drops to +3…+10°C, and the number of rainy days reaches its maximum — precipitation can occur up to 20 days a month.

A feature of the local climate is fairly high humidity during the cold season, so when planning a trip from May to September, be sure to take waterproof clothing with you. Spring and autumn serve as smooth transitional periods when sunny days alternate with overcast ones, and the temperature gradually changes, preparing the city for the change of season.

The climate in Osorno is characterised by moderation, offering travellers fairly mild conditions without exhausting heat. The warmest period of the year is January and February, when summer arrives in the Southern Hemisphere. During these months, the average air temperature is around +16...+17°C, and during the day, the thermometer usually rises to a comfortable +21...+23°C. This is a wonderful time to get to know the city and its surroundings, as the weather encourages long walks in the open air.

The winter season, which lasts from June to August, brings noticeable coolness to the region. July is traditionally considered the coldest month: average readings drop to +6.6°C. Nights become chilly with temperatures around +3...+4°C, and daytime warming rarely exceeds +10°C. Although extreme frosts are infrequent here, warm clothing will definitely be required for a trip at this time of year.

An important feature of Osorno's temperature regime is the noticeable daily fluctuations. This is especially pronounced in the summer period, when the difference between the daytime maximum and the nighttime minimum can exceed 10–11 degrees. Even after a sunny and warm day, the evening and night bring freshness when the temperature drops to +10°C, so travellers are recommended to always have a light jacket or sweater with them.

The rainfall pattern in Osorno has a distinct seasonality, which is typical for the southern part of Chile. Travellers should take into account that rainfall distribution here is uneven: the year is divided into a relatively dry summer period and a rather wet winter. Snow falls extremely rarely in the city itself due to moderate temperatures, so the main type of precipitation is rain.

The rainiest season lasts from May to August. The peak of precipitation falls in June, which is considered the wettest month of the year: the highest amount of rainfall is recorded at this time, and it rains on average 20 days a month. In July and August, the situation is similar — about 18–19 rainy days, so an umbrella and waterproof clothing will be mandatory attributes for a trip at this time of year.

Summer months, on the other hand, are the most favourable for walks and excursions. January and February are the driest time in Osorno. For example, in February, the number of rainy days drops to a minimum (about 4 days per month), and the volume of precipitation is insignificant. Transitional seasons (spring and autumn) are characterised by variable cloudiness, when sunny days alternate with overcast ones.

A trip to Osorno requires a thoughtful approach to packing your suitcase, as the weather here can be changeable. In the summer months (from December to February), it is quite warm during the day, so t-shirts and light trousers will come in handy, but evenings are often cool, so be sure to grab a fleece jacket or sweater. Don't forget to put sunscreen and sunglasses in your luggage: the sun in Chile can be very strong even at moderate temperatures.

If your trip is planned for the period from May to September, be prepared for frequent precipitation and a noticeable drop in temperature. At this time of year, the number of rainy days increases significantly, so a high-quality raincoat, a waterproof windbreaker, and water-repellent shoes will become your main allies. The layering principle works best here: a combination of thermal underwear, a warm middle layer, and protective outerwear will allow you to feel comfortable when the temperature drops to 3–5°C.

Regardless of the season, for walking around the city and the picturesque surroundings, choose comfortable, broken-in flat shoes, ideally suited for long walks. Since rains are possible even in the warm spring and autumn months, a compact umbrella or a light rain cape will not take up much space in your backpack but may prove very useful. Such a set of items will ensure your comfort and allow you to enjoy your journey without being distracted by the whims of nature.
