"Winter" months in this region of Guatemala are a relative concept. In December and January, which are considered the coolest of the year, the weather becomes milder and more comfortable for long excursions. The average temperature during this period stays around 23–24°C. During the day, the air warms up to a pleasant 26°C, allowing you to enjoy nature without the exhausting heat.

Even in the hottest months, nights bring only relative freshness, as temperatures rarely drop below 20°C. For example, in May, after the daytime heat, night-time figures stop at around 24–25°C.

Rio Dulce has a humid tropical climate, so precipitation is a frequent and common occurrence here. Thanks to this, the region is bathed in lush greenery all year round. Tourists should be prepared for rain in any month; however, periods of higher and lower humidity are clearly visible throughout the year. There is no snow here; all precipitation falls exclusively as rain.

The rainiest season starts in June and lasts until October. During these months, the sky is often cloudy, and it rains almost daily. The peak of precipitation occurs in July, when up to 30 rainy days are recorded. Despite the high frequency of rain, it often takes the form of brief but heavy tropical downpours, after which the sun may come out again.

A relatively dry period lasts from February to April. This is the best time for those who want to minimize the chance of getting wet. The "driest" month is considered to be April: the number of days with precipitation decreases to about 13, and the volume of moisture becomes minimal (about 2 mm). Nevertheless, even in this season, light rain is possible, so bringing a raincoat won't hurt.

When heading to Rio Dulce, prepare for the warm and humid tropical climate that prevails here year-round. Your wardrobe should be based on light items made from natural breathable fabrics, such as cotton or linen, as well as quick-drying synthetics, which are especially useful due to high humidity. Since temperatures even in the "coolest" months (December and January) rarely drop below 20°C at night, and can reach 33°C during the day in April and May, shorts, t-shirts, and light dresses are the ideal choice. Don't forget your swimwear, as many activities here are water-related.

Special attention should be paid to rain protection, as precipitation in this region is frequent in any season. Even in the driest month, April, statistics show about 13 rainy days, and in summer and autumn, it can rain almost every day. Therefore, a light but reliable rain poncho or a compact umbrella are essential items in your suitcase. Footwear should be as comfortable and non-slip as possible: light trekking sneakers are suitable for excursions, while sandals that aren't afraid of getting wet are perfect for relaxing by the water.

Despite the cloud cover, the sun in Guatemala is very active, so be sure to bring sunscreen with a high SPF, a cap or wide-brimmed hat, and sunglasses. For evening walks by the river or boat trips, when a cool breeze may be felt, layering is recommended: bring a light windbreaker or a thin fleece. Also, don't forget to pack a high-quality repellent, as the warm and humid climate encourages insect activity.
