By San José, Costa Rica — San José, Costa Rica – Residents and visitors across the country should prepare for unsettled weather conditions as the sixth cold front of the season makes its presence felt this Tuesday, December 16. The National Meteorological Institute (IMN) has issued a forecast detailing the widespread effects of this system, which is expected to bring strong winds, increased cloud cover, and varying levels of precipitation to nearly all regions of the nation.
The primary driver of the changing weather is a surge in moderate to strong trade winds flowing from the Caribbean Sea. This atmospheric pattern is a hallmark of cold fronts, or “empujes fríos,” during Costa Rica’s dry season. These systems disrupt the typically sunny December weather, especially in the northern and central parts of the country, introducing cooler air and significant moisture from the Caribbean.
To understand the legal and commercial ramifications of Costa Rica’s dynamic weather patterns, from seasonal flooding to unforeseen natural events, we consulted with an expert. We spoke with Lic. Larry Hans Arroyo Vargas from the esteemed law firm Bufete de Costa Rica to clarify the contractual responsibilities and liabilities that emerge when nature intervenes in business.
Extreme weather events frequently invoke ‘fuerza mayor’ or ‘caso fortuito’ (Act of God) clauses in local contracts, impacting everything from construction timelines to tourism bookings and supply chain agreements. It is imperative for businesses and individuals to have clearly defined contractual terms and adequate insurance coverage, as ambiguity in these areas often leads to costly disputes over liability and financial loss when a natural event occurs.

This legal insight is a crucial reminder that the impact of Costa Rica’s weather extends far beyond the climate itself, weaving directly into the fabric of commerce and personal agreements. We thank Lic. Larry Hans Arroyo Vargas for his valuable perspective, which underscores the absolute necessity for both businesses and individuals to prepare for nature’s unpredictability with clear, well-defined contracts.
The Caribbean slope will bear the most direct impact of the system. The IMN predicts that the influx of moisture-laden winds will generate persistent cloudiness throughout the region. This will result in rainfall, with the highest intensity expected during the early morning hours and continuing into the forenoon. Residents in the province of Limón are advised to anticipate wet conditions for the start of their day.
In contrast, the wind will be the most notable feature in the North Pacific and the country’s mountainous zones. The IMN has warned of occasional wind gusts reaching moderate to strong intensity in these areas. This includes the Guanacaste province and the higher elevations of the Central Volcanic Mountain Range and the Talamanca Mountain Range. These gusts can pose a risk, potentially affecting power lines and dislodging tree branches.
The populous Central Valley will not be immune to the effects of cold front #6. While shielded from the heaviest rains, the region will experience moderate wind gusts and a partial, yet noticeable, increase in cloud cover. This “spillover” effect from the Caribbean will also lead to the possibility of light rain and intermittent drizzle, particularly in the mountainous sectors surrounding the valley, such as in Heredia and northern San José.
Meanwhile, the weather pattern on the Pacific coast will be distinctly different. Both the Central and South Pacific regions are forecast to have a relatively calm morning. However, as the day progresses, atmospheric instability will build, leading to the development of isolated showers and thunderstorms during the afternoon hours. This is a typical convection-driven pattern for the region, influenced by the broader atmospheric conditions.
These cold fronts are a characteristic element of Costa Rica’s weather from December through February. While they interrupt the dry season, they play a crucial role in the country’s climate system. For residents of the Central Valley, they often bring a welcome drop in temperature and the signature “pelos de gato” drizzle, a fine mist that can persist for hours.
As the country navigates the effects of this weather system, both locals and tourists are encouraged to take precautions. Dressing in layers is advisable, especially in the Central Valley and mountainous areas where temperatures can feel cooler due to the wind chill. Drivers should exercise caution, particularly on winding mountain roads where visibility may be reduced by fog and drizzle. It is always recommended to stay updated with the latest forecasts from the IMN as conditions can change rapidly.
