I'll be trekking in and around the French Alps in the end of April (around the time the snow is melting). A lot of the trails are going to be snowy at this time, especially above 1000m

I'm not looking for a product recommendation, but where should I start in estimating the snowline at this time of year (this will dictate kit necessary and routes available)?

Some additional notes:

  • I have considered using temperature, but this will not be reliable (often hot in ski resorts during the day around this time but still plenty of snow).
  • I realise this will be different depending on the year's snow conditions/temperature/weather
  • @downvoter care to explain? – User632716 Jan 15 '18 at 19:12
  • I don't see how anyone could begin to answer this. Are you asking for a weather forecast 3 months ahead? – user67901 Jan 15 '18 at 21:01

    You can likely google what past conditions are and prepare for the average predictions. igluski.com/snow-history – doctordonna Jan 15 '18 at 21:48
  • You’ll probably have a very different results on the north and south sides of a valley, won’t you? – jcaron Jan 16 '18 at 13:21

It depends on too many variables - the overall snowpack, the duration of snowstorms between now, the duration and depth of cold snaps, cloud cover (10 C on a cloudy day melts much less snow than 10 C on a sunny day)... all you can really do is look at historical norms to get a sense of what your probabilities are.
