Weather Briefing
VFRJuan Santamaría International Airport is currently reporting visual flight rules (VFR) conditions with scattered clouds at 12,000 feet and 10 miles or greater visibility.
Wind Analysis
Winds are from the east (100°) at 3 knots.
Visibility & Ceiling
Visibility is unrestricted. No ceiling exists. Cloud layers reported: few at 3,500 ft, scattered at 12,000 ft.
Temperature & Moisture
Temperature is 21°C (70°F) with a dewpoint of 20°C. The temperature-dewpoint spread is very narrow, indicating saturated or near-saturated air. Fog formation or low cloud development is likely. High temperatures at this elevation may result in significant density altitude effects. Pilots should calculate density altitude and adjust performance expectations accordingly.
Forecast Outlook
The TAF forecast covers the next 24 hours. The forecast shows a transition between VFR and IFR conditions. Pilots should monitor the forecast closely and have an alternate airport plan. Expected weather includes: Thunderstorm Rain. Temporary IFR conditions are forecast with Thunderstorm Rain between 19:00Z and 23:00Z.
Pilot Recommendations
Conditions are favorable for visual flight. The narrow temperature-dewpoint spread creates risk of fog formation, particularly during evening and early morning hours. The forecast indicates conditions may deteriorate. Ensure you have fuel reserves and a viable alternate airport.
This briefing is generated from real-time METAR and TAF data. Always verify with official sources before flight.

About Juan Santamaría International Airport
Overview
Juan Santamaría International Airport serves as Costa Rica's primary international aviation hub, located near San José in the Alajuela province. As a large airport situated at 3021 feet mean sea level, it provides critical aviation infrastructure for both commercial and regional air transportation in Central America.
Flying Conditions
The airport's elevation of 3021 feet means pilots should anticipate higher density altitude conditions, particularly during warmer periods which can affect aircraft performance. Its geographic location in Central America suggests potential for variable weather patterns, with potential rapid atmospheric changes typical of mountainous tropical environments.
Notable Features
The single runway 07/25 measures 9882 feet in length, constructed with asphalt surface, providing substantial operational flexibility for a wide range of aircraft types. Its orientation suggests potential crosswind considerations, with runway heading aligned approximately east-west and positioned at coordinates 9.993860, -84.208801.
Approach Considerations
Pilots should be prepared for potential terrain-influenced wind variations given the airport's mountainous regional context. The substantial 9882-foot runway length provides significant margin for most commercial and regional aircraft operations, allowing flexible approach and landing strategies across various meteorological conditions.
