Weather Briefing
IFRNantucket Memorial Airport is currently reporting instrument flight rules (IFR) conditions with overcast skies at 10,000 feet and 10 SM visibility.
Wind Analysis
Winds are from the north-northwest (340°) at 8 knots. Runway 33 is favored with a 8-knot headwind and 1-knot crosswind component.
Visibility & Ceiling
Visibility is 10 SM. The ceiling is 800 feet AGL (broken). Only precision approaches may be usable depending on minimums.
Temperature & Moisture
Temperature is 13°C (55°F) with a dewpoint of 11°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 21 hours. Conditions are expected to remain IFR throughout the forecast period. Expected weather includes: Light Showers Rain, Mist, Mist.
Pilot Recommendations
An instrument rating and IFR flight plan are required. Verify that destination and alternate approach minimums are above current and forecast conditions. 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 Nantucket Memorial Airport
Overview
Nantucket Memorial Airport serves as the primary aviation gateway to Nantucket Island, located off the coast of Massachusetts. As a medium-sized airport with three runways, it supports commercial, private, and seasonal aviation traffic. The airport's elevation of 47 feet MSL reflects its coastal island environment.
Flying Conditions
Weather at Nantucket Memorial Airport demonstrates significant variability, with Visual Flight Rules (VFR) conditions predominating at 71.7% of observations. Prevailing westerly winds averaging 12 knots and temperatures ranging from -9°C to 26°C create diverse flying conditions. October, November, and September offer the most consistently favorable VFR weather, with minimal precipitation and stable atmospheric conditions.
Notable Features
The airport features three asphalt runways with lengths ranging from 2,696 to 6,303 feet, providing flexibility for different aircraft types. All three runways demonstrate 100% favorable wind alignment, with modest average crosswind components between 7.3 and 7.9 knots. The coastal location influences local meteorological patterns, with occasional fog events occurring in 4.3% of observations.
Approach Considerations
Pilots should anticipate potential reduced visibility scenarios, as 3.1% of observations report visibility below 3 statute miles. The longest runway (06/24 at 6,303 feet) offers the most comprehensive approach options. Wind data suggests westerly approaches are typically most favorable, with calm conditions present in 3.3% of observations. Standard maritime coastal approach considerations should be employed, accounting for potential wind shear and rapidly changing conditions.
