George Bush Intcntl/Houston Airport to San Francisco International IAH → SFO

1,419 nautical miles (1,632 statute miles) northwest on a straight line, true course 296°, about 293° magnetic at the departure end (variation 3E). At 120 knots that is 11 h 44 min at the quickest height in today's winds (4,500 ft, a 1-knot tailwind), arriving about 4:22 pm PDT (23:22 UTC). Right now IAH is VFR, wind from the east (090°) at 5 knots; SFO is VFR, wind from the west (260°) at 4 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: 7,204 flights in the DOT's last twelve reported months, the route's page.

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 4W: moderate turbulence above 18,000 ft (due to mountain wave) from 34,000 ft to 43,000 ft. Over the route from 629 to 929 nm out.
AIRMET TANGO 1W: low-level wind shear (due to air speed loss or gain of 20 knots or more below 2,000 ft above the ground). Over the route from 749 to 879 nm out.
AIRMET TANGO 1W: moderate turbulence below 18,000 ft (due to mountain wave) up to 12,000 ft. Over the route from 849 to 1179 nm out.
AIRMET SIERRA 1E: mountains obscured by cloud (due to mountains obscured by clouds, precipitation, mist). Over the route from 859 to 999 nm out.
AIRMET SIERRA 2E: low cloud or poor visibility (IFR conditions) (due to ceilings below 1,000 ft, visibility below 3 miles, precipitation, mist). Over the route from 879 to 989 nm out.
AIRMET ZULU 2C: moderate icing up to 23,000 ft. Over the route from 1079 to 1089 nm out.
AIRMET TANGO 1W: moderate turbulence above 18,000 ft from 18,000 ft to 39,000 ft. Over the last 180 nm of the route.
AIRMET SIERRA 2E: mountains obscured by cloud (due to mountains obscured by clouds, precipitation, mist). Over the route from 1249 to 1309 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 IAH.

Winds aloft along the route, and the time en route the forecast for use 08:00–15:00 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 12 forecast points nearest it (CLL, ABI, LBB, INK, ROW, ABQ, FMN, PRC, LAS, BIH, FAT, SFO). A plus sign is a headwind, a minus sign a tailwind.

Based on data from the 12th at 06:00 UTC; valid on the 12th at 12:00 UTC for use 08:00 to 15:00 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.
