Weather Briefing

MVFR

Sendai Airport is currently reporting marginal VFR (MVFR) conditions with overcast skies at 2,000 feet and 10 miles or greater visibility.

Wind Analysis

Winds are from the west (270°) at 3 knots.

Visibility & Ceiling

Visibility is unrestricted. The ceiling is 1200 feet AGL (broken), placing conditions in the MVFR category.

Temperature & Moisture

Temperature is 12°C (54°F) with a dewpoint of 9°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 30 hours. The forecast shows a transition between VFR and IFR conditions. Pilots should monitor the forecast closely and have an alternate airport plan. Temporary IFR conditions are forecast between 19:00Z and 22:00Z.

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. The forecast indicates conditions may deteriorate. Ensure you have fuel reserves and a viable alternate airport.

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

About Sendai Airport

Overview

Sendai Airport is a significant international airport located in Natori, Miyagi Prefecture, Japan. Serving the Sendai metropolitan area, this large airport operates at an elevation of 15 feet above mean sea level. Its strategic location and two asphalted runways make it an important transportation hub for the Tohoku region.

Flying Conditions

The airport's low elevation of 15 ft MSL suggests minimal terrain-related weather challenges. Situated at coordinates 38.139702, 140.917007, Sendai experiences typical maritime climate conditions characteristic of northern Japan. Pilots should anticipate potential seasonal variations in wind and visibility that are common to coastal airport environments.

Notable Features

Sendai Airport features two runways: a primary 9,842-foot runway (09/27) and a secondary 3,940-foot runway (12/30), both constructed with asphalt surfaces. The dual-runway configuration provides operational flexibility for different wind conditions and aircraft types. Its coastal location near 38°N latitude indicates potential for complex local meteorological interactions.

Approach Considerations

The runway orientation (09/27 and 12/30) offers multiple approach options depending on prevailing wind conditions. The substantial length of the primary runway (9,842 ft) accommodates a wide range of aircraft types and provides ample landing and takeoff capabilities. Pilots should carefully assess wind direction and runway conditions when planning arrivals and departures.
