Weather Briefing

VFR

San Salvador Airport is currently reporting visual flight rules (VFR) conditions with overcast skies at 3,700 feet and 10 miles or greater visibility.

Wind Analysis

Winds are from the south (180°) at 3 knots.

Visibility & Ceiling

Visibility is unrestricted. The ceiling is 3700 feet AGL (overcast), well above standard VFR minimums.

Temperature & Moisture

Temperature is 24°C (75°F) with a dewpoint of 23°C. The temperature-dewpoint spread is very narrow, indicating saturated or near-saturated air. Fog formation or low cloud development is likely.

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.

This briefing is generated from real-time METAR and TAF data. Always verify with official sources before flight.

Flying Conditions

The airport experiences predominantly VFR conditions 80.2% of the time, with occasional MVFR conditions at 14%. Temperatures range from 15°C to 33°C, with an average of 25.9°C. Wind conditions are consistently from the east at 90 degrees, averaging 7.6 knots with maximum gusts up to 23 knots, and calm periods occurring 2.5% of the time.

Notable Features

The airport's low elevation of 24 feet MSL indicates a flat terrain environment with minimal terrain-related challenges. Wind patterns are remarkably consistent, with 100% favorable wind conditions for runway 10/28. Average crosswind components are relatively mild at 3.9 knots, suggesting generally stable approach conditions.

Approach Considerations

Optimal VFR flying conditions are most prevalent during October, November, and September. The consistent easterly winds favor runway 10/28, providing predictable approach and departure scenarios. With an average visibility of 10 statute miles and zero reported fog incidents, pilots can expect generally clear approach conditions.
