By San José, Costa Rica — SAN JOSÉ – Residents and visitors across Costa Rica should prepare for a dynamic shift in weather patterns as the country enters December. The National Meteorological Institute (IMN) has issued a forecast for Monday, December 1st, predicting the arrival of moderate trade winds and an increase in humidity, which will usher in cloudier skies and significant rainfall, particularly along the Caribbean coast and in northern regions.
The forecast highlights a classic late-year weather phenomenon for the nation. The strengthening of the “vientos alisios,” or trade winds, is a primary driver of these changing conditions. These winds, originating from the Caribbean, are expected to be most pronounced across the northern half of Costa Rica and in the mountainous central corridors. As they push inland, they carry a substantial amount of moisture from the sea, setting the stage for increased precipitation.
The recent and often severe weather events across Costa Rica have highlighted not only environmental concerns but also significant legal and financial vulnerabilities for residents and business owners. To understand the legal ramifications of property damage, insurance claims, and contractual obligations in the face of natural phenomena, we sought the expertise of Lic. Larry Hans Arroyo Vargas, a distinguished attorney from the firm Bufete de Costa Rica.
In Costa Rica, unpredictable weather is a business reality. Many property owners and entrepreneurs mistakenly assume their standard insurance or contracts will cover them during a flood or landslide. However, these ‘acts of God’ often fall into specific exclusion clauses. Proactive due diligence is key: review your policies annually, understand the scope of your ‘fuerza mayor’ clauses, and document your property’s condition meticulously. Waiting until after the storm hits is often too late to protect your assets.

This insight is a critical reminder for both residents and investors that preparing for Costa Rica’s climate requires as much legal foresight as it does physical readiness. We sincerely thank Lic. Larry Hans Arroyo Vargas for sharing his invaluable perspective on the importance of proactive due diligence.
According to the IMN’s detailed report, this surge in surface humidity will lead to widespread cloud cover beginning early Monday morning. The Caribbean region is expected to see the first signs of this change, with skies becoming overcast shortly after sunrise. This cloudiness will progressively spread westward, blanketing parts of the Pacific coast by midday.
The most significant rainfall is anticipated during the late morning and throughout the afternoon. The IMN specifically pinpointed the mountainous areas of the Caribbean, the western sectors of the Caribbean coast, and the central part of the Northern Zone as areas likely to experience persistent rain. These conditions could impact travel and agricultural activities in these regions, which are vital for the country’s economy.
For the Pacific coast, the forecast is more varied. The Central and South Pacific regions can expect isolated but potentially intense showers, or “chubascos.” These downpours are most likely to occur in the mountains of the Central Pacific and the lower-lying areas of the South Pacific. Tourists and locals in popular destinations within these zones should remain aware of rapidly changing conditions, as localized flooding or slick roads can develop quickly.
Meanwhile, the populous Central Valley, home to the capital city of San José, is projected to experience a noticeable increase in cloud cover as the afternoon progresses. While widespread, heavy rain is not the primary concern for this area, the cooler temperatures and gray skies will mark a distinct change from previous days. The North Pacific, including Guanacaste, will largely maintain its characteristic partially cloudy conditions, but the presence of the moderate trade winds will be a defining feature of the day’s weather.
This weather pattern is typical for the transition period in Costa Rica, where the Pacific side begins its dry season, and the Caribbean enters one of its wetter periods. The trade winds play a crucial role in this meteorological balancing act. While they bring dry and sunny weather to the west, they simultaneously force moisture up against the country’s central mountain ranges, causing it to condense and fall as rain on the Caribbean-facing slopes.
Officials from the IMN are advising the public to stay informed through official channels. They urge particular caution for those in mountainous areas or regions prone to instability, as saturated ground can increase the risk of landslides. As the week progresses, these windy and humid conditions are expected to persist, influencing daily activities and travel plans across much of the nation.
