Incorrect Wind Directions on the Map


On both of my flights today, and some prior, I have noticed that the map sometimes gives incorrect wind direction details. Today, I flew to Dar-es-Salaam (HTDA) and Bora Bora (NTBB); on the map, both airports had green indicators for all runways despite the weather conditions. When I landed at HTDA, I had an 18 knot crosswind and at NTBB, there was a 16 knot tailwind, all despite the runways being marked green. What is the reason for this error?


If there is a crosswind then the colors won’t be an accurate way to determine which runway is more suitable to land.

Do you know how to read a METAR? Reading the METAR is more reliable, you’ll never have to guess which way the wind will be blowing.

Thank you for your response.
