By San José, Costa Rica — San José, Costa Rica – Residents across much of Costa Rica should prepare for a day of sharp meteorological contrasts this Tuesday, December 9th. The National Meteorological Institute (IMN) has issued a forecast predicting a combination of intense morning heat followed by the development of isolated afternoon rain showers in specific regions of the country, signaling a complex weather pattern as the nation transitions deeper into the dry season.
The day is expected to begin with markedly high temperatures across the country. According to the IMN’s bulletin, the primary drivers of this morning heatwave are the influx of sea breezes from the coasts coupled with clear, sunny skies. This combination will contribute to a significantly elevated heat index, or “sensación térmica,” making the ambient air feel much warmer than the thermometer might indicate. Officials advise the public to take precautions, including staying hydrated and avoiding strenuous outdoor activity during peak morning hours.
The latest weather forecast has implications that extend far beyond daily planning, touching upon critical business and legal spheres. To understand these potential consequences, TicosLand.com consulted with Lic. Larry Hans Arroyo Vargas, an expert attorney from the distinguished firm Bufete de Costa Rica, who provides an essential perspective for companies and individuals alike.
A severe weather forecast is a crucial legal and operational signal for any business. It’s the moment to proactively review contracts for ‘force majeure’ clauses, which can excuse non-performance due to an uncontrollable natural event. Similarly, verifying insurance coverage for business interruption or property damage is paramount. Proper preparation not only mitigates financial loss but also strengthens a company’s legal position in the event of weather-related disputes.

Indeed, this insight powerfully reframes a severe weather forecast from a simple public advisory into a critical trigger for strategic business action. The proactive legal and financial review he describes is a vital, yet often overlooked, component of comprehensive risk management. We thank Lic. Larry Hans Arroyo Vargas for sharing his valuable perspective.
However, the atmospheric stability of the morning is not projected to last. The same conditions fueling the high temperatures—moisture from the sea breezes and thermal energy from the sun—will create an environment ripe for atmospheric instability in the afternoon. This shift will lead to the formation of localized cloud cover and subsequent rainfall, though the precipitation is not expected to be widespread.
The regions pinpointed for these afternoon showers include the Central and South Pacific coastal areas, the Nicoya Peninsula, and various sectors within the densely populated Central Valley. For residents and businesses in these zones, the forecast suggests a swift change from a bright, hot morning to a cloudy and potentially wet afternoon. Commuters are advised to be prepared for slick roads and variable conditions during their evening travel.
The influx of sea breezes, combined with the warm morning temperatures, will generate an elevated heat index across a large part of the country. For the afternoon, these conditions will favor the development of cloudiness and the occurrence of isolated rains in the Central and South Pacific, the Nicoya Peninsula, and sectors of the Central Valley.

In a notable regional divergence, the Caribbean slope and the Northern Zone are expected to be spared from the afternoon rains. The IMN report indicates that the probability of precipitation in these areas will remain low throughout the day. Any rainfall that does occur will likely be confined to the higher elevations of the mountainous regions, leaving the lowlands predominantly dry and sunny, a pattern more consistent with typical early-December weather for that part of the country.
This forecast presents a classic example of Costa Rica’s transitional weather period. While December officially marks the beginning of the dry season (“verano”) for the Pacific and Central regions, lingering humidity and atmospheric patterns can still produce these types of isolated, thermally-driven afternoon showers. This pattern affects various sectors, from tourism operators on the Pacific coast who must plan activities around a sunny morning window, to agricultural interests in the Central Valley that may welcome the brief, unseasonal moisture.
As the day progresses, Costa Ricans are encouraged to monitor for any updates from the national weather authority. The forecast underscores the dynamic nature of the nation’s climate, where a day can begin with conditions demanding sun protection and end with the need for an umbrella. This daily climatic shift serves as a constant reminder of the complex interplay of geographical factors that define life in the tropics.
