10 years of last frost dates, East Malling, Kent

[ef23432]

Hi everyone

I've tried to make a last frost guide using 3500 or so daily measurements from a local weather station in East Malling, Kent.

I'm not sure how reasonable it its - what do you think?

I did the following:

1. Take 10 years of daily minimum temperatures of air (1.25m above ground) and grass (25mm - 50mm above ground).
2. Categorise them by week number (1 - 52 weeks).
3. Group all the same weeks together (e.g. daily minimum temperatures of week 5 from 2010 to 2019) and find the 10th percentile temperature of each week.
4. Graph the data by week

I think doing the percentile thing is trying to make a reasonable worst case scenario: if I plant now, I will be ok according to the past 9 years out of 10 years. I don't know stats though so I'm not sure if this is really the correct way of describing it.

Cheers

Well that`s all too clever for me - I have only just learned how to stick my hand out of the window to see if it`s raining - so I think I`d have a nice big lump of fleece ready just in case
