Wind Analysis

Winds are from the south (170°) at 13 knots with gusts to 19 knots. Runway 18/36 is favored with a 13-knot headwind and 2-knot crosswind component (gusting to 3 knots crosswind).

Visibility & Ceiling

No ceiling exists. Cloud layers reported: few at 12,000 ft.

Temperature & Moisture

Temperature is 26°C (79°F) with a dewpoint of 22°C. The narrow temperature-dewpoint spread suggests high humidity and potential for visibility restrictions, especially during cooling periods.

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.
