Weather Briefing

VFR

Dupage Airport is currently reporting visual flight rules (VFR) conditions with overcast skies at 9,000 feet and 10 SM visibility.

Wind Analysis

Winds are from the northwest (320°) 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 7000 feet AGL (broken), well above standard VFR minimums.

Temperature & Moisture

Temperature is 26°C (79°F) with a dewpoint of 24°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 24 hours. The forecast shows a transition between VFR and IFR conditions. Pilots should monitor the forecast closely and have an alternate airport plan. Expected weather includes: Thunderstorm Rain, Mist. Temporary IFR conditions are forecast with Thunderstorm Rain, Mist between 01:00Z and 05:00Z. There is a 30% probability of IFR conditions with Thunderstorm Rain, Mist between 20:00Z and 00:00Z.

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. 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 Dupage Airport

Overview

DuPage Airport serves the Chicago/West Chicago metropolitan area as a medium-sized airport located west of Chicago. Situated at an elevation of 759 feet MSL, the airport provides crucial general aviation infrastructure for the region, supporting diverse aircraft operations across its four runways.

Flying Conditions

Historical weather data indicates predominantly favorable flying conditions, with 65.1% of observations reporting VFR conditions. Pilots can expect moderate wind conditions, with a prevailing westerly wind at an average of 9.1 knots and occasional gusts up to 30 knots. September through November represent the most consistently favorable VFR months, offering optimal flying weather.

Notable Features

The airport features four runways with varying lengths and surface types, providing flexibility for different aircraft types and operational needs. The two concrete runways (02L/20R and 02R/20L) offer longer surfaces suitable for larger aircraft, while the two asphalt runways (10/28 and 15/33) provide additional operational capacity. Temperature variations range significantly from -24°C to 32°C, indicating potential seasonal operational considerations.

Approach Considerations

All runways demonstrate 100% favorable wind alignment, with relatively consistent crosswind averages between 5.4 and 6 knots. The longer concrete runways (02L/20R at 7570ft and 02R/20L at 5100ft) provide the most substantial landing options. Visibility averages 8.8 statute miles, with only 4.2% of observations reporting visibility below 3 miles and minimal fog occurrence at 1.9%.
