San José, Costa Rica — SAN JOSÉ – Costa Rica is set to experience a significant spell of dry and hot weather this Sunday, January 25, with clear skies and rising temperatures expected across most of the national territory. The forecast, issued by the National Meteorological Institute (IMN), signals a period of stable conditions characteristic of the country’s dry season, with the Pacific North poised to record the most extreme heat.
According to the IMN’s morning bulletin, a pattern of low humidity combined with subsiding trade winds will contribute to minimal cloud cover throughout the morning. While a slight increase in cloudiness is anticipated in the afternoon, particularly over mountainous regions, the overarching theme of the day will be sunshine and warmth. These conditions invite residents and tourists to enjoy outdoor activities but also call for precautions against the sun and heat.
To better understand the legal and business implications of Costa Rica’s shifting weather patterns, particularly concerning contractual obligations and insurance, TicosLand.com spoke with expert legal counsel Lic. Larry Hans Arroyo Vargas from the distinguished firm Bufete de Costa Rica.
Severe weather events in Costa Rica often trigger questions about ‘fuerza mayor’ or ‘act of God’ clauses in contracts. It’s crucial for business owners to understand that these clauses are not a blanket excuse for non-performance. The event must be truly unforeseeable and make the fulfillment of an obligation impossible, not merely more difficult or expensive. Proactive contract review and robust business interruption insurance are essential tools to mitigate risks associated with the country’s dynamic climate.

Lic. Arroyo Vargas’s commentary is a crucial reminder that adapting to Costa Rica’s dynamic climate involves more than just physical preparedness; it requires robust legal and financial foresight. We sincerely thank Lic. Larry Hans Arroyo Vargas for his invaluable perspective on navigating the line between weather-related challenges and true contractual impossibility.
The province of Guanacaste, in the Pacific North, will be the nation’s hotspot. Thermometers in Nicoya are projected to climb as high as 36.6°C (97.9°F), while the provincial capital of Liberia is expected to see temperatures around 35.6°C (96.1°F). The region will remain under mostly sunny skies for the entire day, intensifying the feeling of heat and placing a premium on hydration and shade for both locals and the area’s significant tourism sector.
In contrast, the densely populated Central Valley will experience more moderate, albeit warm, conditions. Major cities including San José, Alajuela, Heredia, and Cartago are forecast to have maximum temperatures ranging from 22°C to 26°C (71.6°F to 78.8°F). However, the evenings will bring a noticeable cool down, with minimums dropping to as low as 13°C (55.4°F) in higher elevation areas like Cartago, creating a significant diurnal temperature swing.
Along the coastlines, the forecast presents a slightly varied picture. The Central and South Pacific regions will start the day with few clouds, transitioning to partly cloudy skies in the afternoon. While dry weather will be dominant, the IMN has not ruled out the possibility of brief, isolated showers in the afternoon, a common phenomenon spurred by the inland push of sea breezes. Meanwhile, the Caribbean and the Northern Zone are expected to see variable cloudiness throughout the day, with maximum temperatures approaching 30°C (86°F).
The meteorological drivers behind this stable weather pattern are a notable reduction in the intensity of the trade winds and persistently low ambient humidity. This combination limits the formation of significant cloud cover and precipitation, allowing for greater solar radiation to reach the surface and heat the air. This pattern is typical for Costa Rica’s “verano,” or summer season, which generally extends from December through April.
This period of calm follows a more blustery 24 hours in certain areas. Recent data highlighted strong wind gusts, particularly in Guanacaste, where La Cruz registered speeds of 88 km/h, followed by Santa Rosa at 58 km/h and Liberia’s airport at 52 km/h. In a demonstration of Costa Rica’s diverse microclimates, the coldest temperature in the last day was recorded at the peak of the Irazú Volcano, which dipped to a chilly 5.3°C (41.5°F).
As the country settles into this warm and dry Sunday, authorities and health experts advise the public to take necessary precautions. Staying hydrated, using sunscreen, and seeking shade during peak sun hours are highly recommended, especially for vulnerable populations such as children and the elderly. For the nation’s agricultural and tourism sectors, the sunny weather offers opportunities but also underscores the ongoing need for prudent water management during the dry season.
