Weather in Puerto Montt

Planning your day in Puerto Montt? Here you will find the latest weather information, including current readings and the forecast for the near future.

The climate of Puerto Montt can be described as temperate oceanic, with mild temperatures and high humidity throughout the year. Thanks to the proximity of the ocean, there is no extreme heat or severe frost here, yet the weather is often changeable. This is a realm of lush greenery and lakes, the nature of which depends directly on regular rainfall.

The seasons here are quite distinct, but temperature changes are not too sharp. Summer (from December to February) is the most comfortable time to visit: the air warms up to an average of +15...+19°C, and rains occur least frequently. Winter (from June to August) brings coolness with average temperatures around +7°C and high cloudiness, but the thermometer rarely drops below +4°C.

The main feature of the local weather is frequent rain, so tourists should be prepared for precipitation in any month. While in summer the number of rainy days ranges from 7 to 12, in the winter period, especially in June, rain can fall for more than 20 days a month. Regardless of the season, a high-quality raincoat and waterproof shoes will become an important part of your luggage when travelling to this picturesque region of Chile.

The temperature regime in Puerto Montt is characterised by mildness and a lack of extreme fluctuations, which is due to the influence of the ocean. The annual temperature graph is quite smooth: the warmest months are traditionally January and February, when the air warms up to a maximum of 18.5–19.6°C. The coldest period falls in June and July, when average daytime readings drop to 7–9°C, and night temperatures reach their annual minimums.

Summer in this region of Chile (from December to February) can be described as pleasantly warm, but not hot. The average temperature stays in a comfortable range of 13–15°C, which is ideal for active tourism, as there is no exhausting heat. Even at the height of the season, nights remain fresh (around 11°C), so travellers are recommended to have warm clothes for evening walks.

Winter (June – August) brings coolness, yet severe frosts practically never occur here. During the day, the air warms up to an average of 7–10°C, and at night the temperature drops to 4.5–5.5°C. It is worth noting that the amplitude of fluctuations between day and night temperatures remains small throughout the year, rarely exceeding 4–8 degrees, which makes the climate predictable and comfortable for the body, provided you are dressed for the weather.

Precipitation in Puerto Montt is a frequent phenomenon that largely shapes the picturesque green landscapes of this Chilean region. The wettest period falls during the local winter months, from May to August. The record holder for rainfall frequency is June: this month sees the highest level of precipitation (about 11 mm), and rain can fall for up to 23 days. At this time of year, travellers will definitely need a reliable raincoat and waterproof footwear.

If you prefer clearer weather, it is best to plan your trip for the summer season, which lasts here from December to March. The driest month is considered to be February, when precipitation drops to a minimum (about 2 mm), and there are only about seven inclement days. January is also favourable for tourism: rains occur less frequently (about 9 days), allowing you to comfortably explore the city and its surroundings.

In the transition seasons, spring and autumn, the weather remains changeable, with the number of rainy days ranging from 13 to 18 per month. Thanks to the mild maritime climate, even in the coldest month, July, the temperature rarely drops to zero, so precipitation falls predominantly as rain or drizzle. Snow in the city itself is an extremely rare phenomenon and uncharacteristic for this region.

The weather in Puerto Montt is known for its variability and coolness, so the golden rule for a tourist here is to dress in layers. Even in the height of summer (January and February), when the average daytime temperature reaches a comfortable 18–19°C, evenings can be quite fresh, so be sure to pack a fleece jacket, a sweater, and a light hat in your suitcase. Given that precipitation falls year-round, and in the winter months (June–August) the number of rainy days exceeds 20, a high-quality waterproof and windproof jacket or a reliable raincoat is an absolute necessity.

If your trip is planned for the period from May to September, be prepared for lower temperatures (averaging from 5°C to 10°C) and high humidity. At this time of year, you cannot do without a set of thermal underwear and insulated outerwear. Pay special attention to footwear: it must be maximally comfortable for walking, warm, and, most importantly, waterproof. For walks around the city and surroundings, trekking boots are excellent, as they will protect your feet from dampness and puddles.

Despite the fact that Puerto Montt is often cloudy, do not neglect sun protection. Ultraviolet radiation in Chile can be intense, so sunscreen and sunglasses will be useful even in overcast weather. An umbrella may not be the most practical accessory here due to potential gusts of wind from the ocean, so it is better to opt for clothing with a hood.
