Thanks to the special microclimate of this region of Argentina, prolonged downpours capable of spoiling a holiday for a long time rarely happen here.

The highest frequency of precipitation is observed at the height of summer and in spring: in January and October, about 9 rainy days are recorded per month. December and March can also bring up to 8 days with precipitation. Despite such periodicity, the total volume of moisture remains small, which suggests the short-term nature of the rains or light drizzle that is quickly replaced by clear weather.

The driest period can be called the winter months (June, August) and the end of autumn (May), when the number of days with precipitation decreases to five. At this time, the air becomes drier and cooler. Snow in the city itself is an atypical phenomenon, as even in the coldest months, for example in July, the average daily temperature stays above 10°C, so precipitation falls predominantly in the form of rain.

When packing for Merlo, it is worth considering the features of the local microclimate, which is famous for its beneficial effects on health. In summer (from December to February), it is quite hot here; during the day, the temperature often rises to +28–30°C, so the basis of your wardrobe should be light items made from natural fabrics: t-shirts, shorts, and summer dresses. Be sure to bring a hat, sunglasses, and cream with a high SPF level, as the sun in this region of Argentina can be very active.

If your trip is planned for the winter months (June–August) or the off-season, prepare for cool nights and moderately warm days. At this time of year, the temperature can drop to +6°C, so the best solution will be the layering principle: a combination of a t-shirt, a fleece jacket, and a windbreaker will allow you to feel comfortable during any weather changes. Even in summer, evenings can be fresh, so a light jacket or sweater will not be amiss in your suitcase at any time of the year.

For walks in the picturesque surroundings and mountain trails, comfortable footwear is necessary, for example, trainers or trekking boots with non-slip soles. Although the volume of rainfall here is small, statistics show the presence of several rainy days in each month, so a compact umbrella or a light raincoat is worth taking with you in case of sudden inclement weather.
