Weather in Bogotá and Colombia from September 23 to 26: Get your umbrella ready for rain, cloudy skies, and unstable days.

The Institute of Hydrology, Meteorology and Environmental Studies (Ideam ) reported its latest weather forecast for the week of September 23-26, 2025, across the country.

Although the first few days will be dominated by partly cloudy skies and dry weather, authorities warn that significant rainfall is expected on Thursday and Friday , with possible impacts in the capital and several municipalities in Cundinamarca.

The capital of the republic begins the week with dry weather, but according to the institute, rainfall will increase between Thursday and Friday.

A cool morning is expected, with temperatures around 9°C. Partly to mostly cloudy skies are expected during the morning and afternoon, with a low chance of rain. Scattered showers are possible in the south of the city at night.

The city will also experience cloudy skies for much of the day, with increasing cloudiness in the afternoon. Localized rain is expected in western and northern Bogotá. Maximum temperatures will be close to 20°C.

The agency forecasts an increase in continuous rainfall beginning early this morning, intensifying in the afternoon. Thunderstorms are possible in the south and east of the capital.

Finally, for the week's close, rain of varying intensity is forecast throughout the day. There's also a higher probability of heavy downpours in the afternoon and evening. The low will reach 10°C and a high of 18°C.

In the rest of the country, the week begins with relatively dry conditions. However, increasing cloudiness and rain of varying intensity are expected on Wednesday and Thursday.

Predominantly dry weather across much of the country. Isolated showers in the Pacific region, the southern Amazon, and the foothills of the Llanos.

Meanwhile, increased cloud cover is expected in the Andean region, along with moderate rain in Antioquia, Tolima, Santanderes, and Cundinamarca. Lightning is also possible in Chocó and Valle del Cauca.

According to IDEAM, this day will be the wettest of the week. Heavy downpours are expected in the Pacific region, the southern Caribbean, Córdoba, Sucre, and the central Andean region. Electrical activity is possible in Antioquia, Cauca, and Nariño.

At the end of the week, rainfall will persist in the Andean region and the Caribbean, with increasing risks of landslides. Likewise, the Amazon region will experience rainfall of varying intensity, with a tendency to decrease towards the evening.

Meanwhile, the outlook for Cundinamarca reflects a high risk level; municipalities such as Mosquera, Choachí, Facatativá, Tenjo, and Subachoque reported minimum temperatures between 1°C and 4°C, which increases the risk in mountainous areas.

In addition, the authorities maintain different alert levels:

Despite the expected rains, Cundinamarca remains under moderate alert for vegetation fires. Municipalities such as Anolaima, Cucunubá, Fúquene, Guachetá, Lenguazaque, Sutatausa, and Ubaté are under alert.

In parallel, there are hydrological alerts due to the probability of sudden floods:

The organization also urged citizens to be alert to changes in the weather and follow preventive measures.

Avoid outdoor activities during thunderstorms, check road conditions before traveling, clean roofs and gutters to prevent flooding, report landslides or emergencies to the appropriate authorities, and stay informed through official channels.
