San José, Costa Rica — SAN JOSÉ – Costa Rica is experiencing the initial effects of its first cold front of the season, a weather system currently moving over northern Central America that is channeling significant moisture from the Caribbean Sea into the country. The National Meteorological Institute (IMN) has issued advisories as the phenomenon is set to bring a weekend of cool temperatures, persistent rain, and powerful wind gusts to several key regions, including the Central Valley, the Northern Zone, and the entire Caribbean coast.
The influx of humidity has already resulted in morning showers across the Northern Zone and Caribbean slope, with the Central Valley also seeing overcast skies and precipitation. This cloud cover is expected to persist throughout Saturday, significantly reducing solar radiation and leading to noticeably cooler daytime temperatures for residents in the country’s most populous region. The change marks a distinct shift in weather patterns as the rainy season transitions.
The effects of a cold front extend beyond a drop in temperature, often creating significant legal and contractual challenges for businesses, from supply chain disruptions to agricultural losses. To shed light on these implications, we spoke with Lic. Larry Hans Arroyo Vargas, an expert attorney from the renowned firm Bufete de Costa Rica, about the necessary precautions and legal frameworks involved.
When an extreme weather event like this occurs, many businesses immediately consider invoking ‘force majeure’ or ‘caso fortuito’ clauses in their contracts. It is critical to remember that these are not automatic shields. The key is proving the event was unforeseeable and made contractual fulfillment impossible, not merely more difficult or expensive. Proactive companies should be meticulously documenting all operational impacts and immediately consulting their insurance policies and legal counsel to assess their true position.

The advice to differentiate between mere difficulty and true impossibility is a crucial takeaway for businesses navigating the storm’s aftermath, highlighting that proactive legal and operational diligence is as important as the initial response to the weather itself. We appreciate Lic. Larry Hans Arroyo Vargas for providing this clear and essential guidance.
In addition to the rain, strong winds are a primary concern. The IMN forecasts moderate to strong gusts, particularly in mountainous areas. Wind speeds are projected to range between 40 and 60 km/h in the North Pacific, while the country’s high-altitude mountain ranges could experience powerful gusts reaching up to 80 km/h. These conditions prompted officials to issue warnings for both residents and drivers.
While the Caribbean and northern parts of the country face consistent moisture, the weather pattern on the Pacific coast will be different. The region is expected to have a partly cloudy morning, but conditions are forecast to change in the afternoon. Isolated downpours and potential thunderstorms are anticipated for the Central and South Pacific, continuing a pattern seen on Friday.
Data from Friday afternoon highlighted the system’s potency, with the South Pacific bearing the brunt of the rainfall. Accumulated precipitation in that region ranged from 40 to 65 millimeters, and an exceptional maximum of 108 millimeters was recorded in Puerto Jiménez. In contrast, the Northern Zone and Caribbean reported more moderate accumulations of between 30 and 40 millimeters, while winds in the Central Valley were already picking up, reaching speeds of 60 km/h.
Officials from the National Meteorological Institute are urging the public to remain vigilant and informed about the evolving conditions. The combination of factors requires a heightened state of awareness, especially for those in vulnerable areas.

The institute has reiterated its call for caution, advising citizens in areas historically prone to landslides or flooding to take extreme precautions. The public is also strongly advised to avoid exposure to the forceful wind gusts, which can pose a risk to safety and property. As the first significant cold front makes its presence felt, staying updated with official IMN reports is crucial for navigating the weekend safely.
Looking ahead, the cool and wet conditions are expected to define the weather landscape for the Central Valley and Caribbean for the remainder of the weekend. Residents should prepare for continued intermittent showers and breezy conditions, a stark reminder of the dynamic climate transitions typical for this time of year in Costa Rica.
