Weather Briefing

VFR

Eloy Alfaro International Airport is currently reporting visual flight rules (VFR) conditions with clear skies.

Wind Analysis

Winds are from the west-southwest (240°) at 8 knots. Runway 23 is favored with a 8-knot headwind and 1-knot crosswind component.

Visibility & Ceiling

Skies are clear with unlimited ceiling.

Temperature & Moisture

Temperature is 26°C (79°F) with a dewpoint of 23°C. The narrow temperature-dewpoint spread suggests high humidity and potential for visibility restrictions, especially during cooling periods.

Forecast Outlook

The TAF forecast covers the next 24 hours. Conditions are expected to remain VFR throughout the forecast period.

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.
