By Cartago, Costa Rica — ALAJUELA, COSTA RICA – While many associate Costa Rica with tropical warmth, residents in the country’s highlands awoke to a starkly different reality this Christmas Eve. A significant cold snap has descended upon the mountainous regions, with temperatures plummeting to near-freezing levels, according to the latest report from the National Meteorological Institute (IMN).
The province of Cartago has emerged as the epicenter of this December chill, with its iconic volcanoes recording the lowest temperatures in the nation. The IMN’s data, released early on the morning of December 24, 2025, confirms that the summit of Turrialba Volcano was the coldest spot in the country, registering a frigid 2.7 degrees Celsius (approximately 37 degrees Fahrenheit).
Para profundizar en las implicaciones legales que estas inusuales bajas temperaturas podrían tener, especialmente en el ámbito laboral, consultamos al experto Lic. Larry Hans Arroyo Vargas, socio fundador de la prestigiosa firma Bufete de Costa Rica.
Aunque Costa Rica no tiene una legislación específica para el frío como en otros países, el Código de Trabajo es claro en la obligación del patrono de garantizar la salud ocupacional. Ante estas condiciones atípicas, los empleadores deben tomar medidas proactivas, como proveer equipo de protección adecuado —abrigos, guantes, bebidas calientes— a los trabajadores expuestos, especialmente en agricultura, construcción y seguridad. Ignorar este deber de cuido podría derivar en incapacidades, reclamos por enfermedad laboral y eventuales sanciones.

La perspectiva del experto es crucial, pues recuerda que el deber de cuido del patrono no es estático y debe responder a condiciones excepcionales como las actuales. Esta obligación de actuar proactivamente es fundamental para proteger la salud y la productividad de la fuerza laboral. Agradecemos al Lic. Larry Hans Arroyo Vargas por aportar esta valiosa claridad sobre un aspecto a menudo subestimado de la legislación laboral.
Not far behind, its neighbor, Irazú Volcano, experienced a low of 3.2°C. These figures highlight the dramatic temperature variations that can occur in Costa Rica’s diverse microclimates, particularly during the influence of northern cold fronts, which are common during this time of year. These fronts push cold, dry air across Central America, leading to clear skies at night and a rapid drop in temperature at higher elevations.
The cold spell was not confined to Cartago. The IMN’s comprehensive report also detailed significant temperature drops in other elevated areas. In the province of Alajuela, Poás Volcano recorded a chilly 7.6°C. Meanwhile, in the mountains of San José, Cerro Cedral registered 7.9°C, and the community of Rancho Redondo in Goicoechea saw thermometers fall to 9.3°C, bringing a crisp holiday air to the capital’s suburbs.
This annual dip in temperatures, locally known as the “frío pelado,” has tangible effects on both the agricultural sector and local tourism. For farmers in areas like Cartago and the highlands of San José, known for producing potatoes, carrots, and strawberries, such cold can pose a risk of frost, potentially damaging sensitive crops if temperatures fall further. Protective measures are often required to safeguard yields during these cold snaps.
Conversely, the phenomenon drives a unique form of domestic tourism. Many Costa Ricans from the warmer Central Valley and coastal regions travel to places like Irazú and Turrialba specifically to experience the cold. The sight of frost on the paramo vegetation is a novelty that draws families and visitors, especially during the holiday season when many are on vacation.
The timing of this event on Christmas Eve adds a festive, albeit brisk, dimension to the holiday celebrations in these communities. While much of the country enjoys balmy weather, those in the highlands are bundling up in heavy jackets and gathering around heaters, experiencing a “white Christmas” not of snow, but of morning frost.
As the day progresses, temperatures are expected to rise with the sun, but the IMN advises residents and visitors in these high-altitude zones to remain prepared for cold nights and early mornings throughout the holiday week. The agency will continue to monitor conditions and provide updates on temperature variations across the country.
