San Diego International to Lewiston/Nez Perce County SAN → LWS

819 nautical miles (943 statute miles) north on a straight line, true course 001°, about 350° magnetic at the departure end (variation 11E). At 120 knots that is 4 h 46 min at the quickest height in today's winds (30,000 ft, a 52-knot tailwind), arriving about 10:40 pm PDT (05:40 UTC), after sunset at the destination. Right now SAN is VFR, wind from the west-southwest (250°) at 6 knots; LWS is VFR, wind from the west (270°) at 7 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: 1 flights in the DOT's last twelve reported months, the route's page.

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 7 forecast points nearest it (SAN, ONT, WJF, BIH, BAM, BOI, LWS). A plus sign is a headwind, a minus sign a tailwind.

Based on data from the 11th at 18:00 UTC; valid on the 12th at 00:00 UTC for use 20:00 to 03:00 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.
