Oakland San Francisco Bay Airport to Daniel K Inouye International OAK → HNL
2,091 nautical miles (2,407 statute miles) west on a straight line, true course 252°, about 238° magnetic at the departure end (variation 14E). At 120 knots that is 13 h 29 min at the quickest height in today's winds (24,000 ft, a 35-knot tailwind), arriving about 8:50 am HST (18:50 UTC). Right now OAK is VFR, wind from the south-southwest (210°) at 7 knots; HNL is VFR, wind from the east-northeast (060°) at 9 knots. For planning, not a briefing: the legal preflight briefing comes from Flight Service (1-800-WX-BRIEF) or the FAA's own tools. Airlines fly this pair: 2,272 flights in the DOT's last twelve reported months, the route's page.
The route the straight line, the warnings crossed, restrictions, pilot reports and the airports along the way · click a mark for its words
Green, blue, red and purple airport dots are the flying conditions reported there now (VFR, marginal VFR, IFR, low IFR); grey means no report. Red areas are SIGMETs, orange areas AIRMETs, hatched red areas temporary flight restrictions. Map tiles: OpenFreeMap, data © OpenStreetMap contributors.
Warnings the route crosses SIGMETs and AIRMETs whose area the line passes through or comes within 25 nm of
- AIRMET TANGO 1W: moderate turbulence above 18,000 ft from 18,000 ft to 39,000 ft. Over the first 139 nm of the route.
- AIRMET TANGO 2W: strong surface winds (30 knots or more) (due to sustained surface winds greater than 30 knots). Over the route from 120 to 139 nm out.
A SIGMET warns of weather hazardous to all aircraft; an AIRMET of weather that matters to small aircraft and to flying without instruments. "From 60 to 180 nm out" is measured along the route from OAK.
Pilot reports along the route within 50 nm of the line, last three hours, the serious ones first
- B38M at 25,000 ft, 4 nm south, 8:31 pm PDT (03:31 UTC): moderate turbulence from 21,000 ft to 25,000 ft, remarks: entered by zoa fdcs. At the departure end, 4 nm south of the line.

Winds aloft along the route, and the time en route the forecast for use 02:00–09:00 UTC · at 120 knots true airspeed
The westbound cruising heights for this course (VFR: even thousands plus 500 ft; above 18,000 ft the forecast levels), with the wind averaged along the line from the 2 forecast points nearest it (SFO, FOT). A plus sign is a headwind, a minus sign a tailwind.

Based on data from the 12th at 00:00 UTC; valid on the 12th at 06:00 UTC for use 02:00 to 09:00 UTC; temperatures above 24,000 ft are below zero. Heights are above sea level; a height is left out when the forecast has no wind for it over most of the line (the ground is higher). Ground speed is the airspeed less the headwind; the time en route is for the straight line and ignores climb, descent and routing around weather.
