Weather Briefing

VFR

Semnan Municipal Airport is currently reporting visual flight rules (VFR) conditions with few clouds at 3,500 feet and 10 miles or greater visibility. Note: This observation is 410.6 hours old and conditions may have changed.

Wind Analysis

Winds are from the north (360°) at 10 knots with gusts to 19 knots. Runway 04/22 is favored with a 8-knot headwind and 6-knot crosswind component (gusting to 12 knots crosswind).

Visibility & Ceiling

Visibility is unrestricted. No ceiling exists. Cloud layers reported: few at 3,500 ft.

Temperature & Moisture

Temperature is 25°C (77°F) with a dewpoint of 5°C, indicating very dry conditions. High temperatures at this elevation may result in significant density altitude effects. Pilots should calculate density altitude and adjust performance expectations accordingly.

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.
