Monday 28 September · ALL DAY

08:00 - 18:00 · 9-17 °C · D+1, hour confidence · models disagree
  • crosswind 0-2 kt, runway 15
  • est. base 200-3400 ft at 0-15% low cloud
  • visibility 0-24 km
  • models disagree - treat the timing as provisional
  • ceiling is a model estimate - no observation exists for EVAD

Sunrise 07:19, sunset 19:06, on the ground by 18:06 (Europe/Riga). The landing deadline is 60 min (the default margin) before sunset. Sun times are computed from the solar position, not taken from the AIP.

Hour by hour

Every value is the median of the three models. Under crosswind, base, low cloud and visibility, a small second line gives each model's own figure (ECMWF · ICON-EU · GFS), so you can see when they disagree. A gust marked (?) came from a model whose gust figure is implausible at that wind speed.

The base is an estimate

The base is an Espy estimate from model temperature and dew point, read beside low-cloud cover. It is not a measured ceiling. Aim for 2000 ft and make the final call on the day.
