Weather Briefing

MVFR

Union Island International Airport is currently reporting marginal VFR (MVFR) conditions with broken clouds at 1,600 feet and 10 miles or greater visibility. Note: This observation is 6 hours old and conditions may have changed.

Wind Analysis

Winds are from the east-northeast (60°) at 4 knots with gusts to 15 knots.

Visibility & Ceiling

Visibility is unrestricted. The ceiling is 1600 feet AGL (broken), placing conditions in the MVFR category.

Temperature & Moisture

Temperature is 26°C (79°F) with a dewpoint of 25°C. The temperature-dewpoint spread is very narrow, indicating saturated or near-saturated air. Fog formation or low cloud development is likely.

Forecast Outlook

The TAF forecast covers the next 24 hours. Conditions are expected to remain VFR throughout the forecast period. Expected weather includes: Showers Rain. There is a 30% probability of VFR conditions with Showers Rain between 18:00Z and 04:00Z.

Pilot Recommendations

VFR pilots should exercise caution. Consider filing IFR if instrument rated, or postponing the flight if conditions are expected to deteriorate further. 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.

About Union Island International Airport

Overview

Union Island International Airport serves the small Caribbean island of Union Island, located in Saint Vincent and the Grenadines. As a medium-sized airport situated at a low elevation of 16 feet above mean sea level, it provides critical air transportation infrastructure for this island community. The airport supports regional and inter-island aviation connectivity in the southeastern Caribbean region.

Flying Conditions

Caribbean maritime environments typically feature consistent trade winds and potential tropical weather systems. Pilots should anticipate potential convective activity and localized wind variations due to the island's topography. The airport's low elevation minimizes significant altitude-related atmospheric complications for arriving and departing aircraft.

Notable Features

Union Island's geographic position presents unique terrain considerations for pilots, with surrounding mountainous landscape potentially influencing local wind patterns and approach dynamics. The airport's coordinates at 12.600135, -61.411945 indicate its location within a complex archipelagic environment that requires careful navigation and situational awareness. Surrounding terrain and coastal proximity will impact standard flight operations.

Approach Considerations

Given the island's location and maritime setting, pilots should prepare for potential crosswind conditions during approach and landing. The airport's low elevation and island setting suggest wind direction may vary rapidly, requiring precise airmanship and continuous environmental assessment. Standard regional Caribbean approach protocols are recommended for safe aircraft handling.
