Weather Briefing

VFR

Cyril E. King Airport is currently reporting visual flight rules (VFR) conditions with few clouds at 3,000 feet and 10 SM visibility.

Wind Analysis

Winds are from the east-southeast (110°) at 13 knots with gusts to 21 knots. Runway 10/28 is favored with a 13-knot headwind and 2-knot crosswind component (gusting to 4 knots crosswind).

Visibility & Ceiling

Visibility is 10 SM. No ceiling exists. Cloud layers reported: few at 3,000 ft.

Temperature & Moisture

Temperature is 31°C (88°F) with a dewpoint of 23°C, indicating moderate moisture conditions. 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 22 hours. Conditions are expected to remain VFR throughout the forecast period.

Pilot Recommendations

Conditions are favorable for visual flight.

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

About Cyril E. King Airport

Overview

Cyril E. King Airport serves Charlotte Amalie, located in the U.S. Virgin Islands, functioning as a critical medium-sized airport for regional and international transportation. Situated at 23 feet above mean sea level with coordinates 18.337091, -64.977251, the airport provides essential aviation infrastructure for the Caribbean region.

Flying Conditions

Weather conditions at TIST are predominantly favorable for visual flight rules (VFR), with 94.2% of observations supporting VFR operations. The airport experiences consistent easterly winds averaging 8.4 knots, with temperatures ranging from 21°C to 34°C and an average visibility of 9.8 statute miles. January, November, and December represent the most consistently good VFR months for operations.

Notable Features

The airport features a single runway (10/28) measuring 7,000 feet with an asphalt surface. Wind conditions heavily favor runway alignment, with 100% wind compatibility and an average crosswind of only 3.5 knots. The geographic location in the Caribbean creates a relatively stable meteorological environment with minimal adverse weather interruptions.

Approach Considerations

Runway 10/28 presents predictable approach conditions, with easterly winds consistently supporting operations. Pilots can expect minimal meteorological challenges, with IFR conditions occurring in less than 1.2% of observations. The low occurrence of low visibility events (fog at 0%, visibility below 3SM at 0.5%) suggests generally reliable visual approach opportunities.
