NOTE The Average Minimum Dew-Point Temperature could
be a little out due to my weather stations range only going as low as 0°C (only
for Dew-Point Temps). I have set an out-of-range value of -3.0°C for this (still
my default value). I recorded 24 days which were out of the Dew-Point
Temperature range for the month of July.
RECENT ADDITIONS TO STATISTICS LIST
1.
I have now included the Monthly Prevailing Wind Direction in my monthly
weather summaries (as you may have noticed).
2.
I have changed the wording from Minimum Ground Temperature to be Minimum
Grass Temperature as I think that this is more technically correct and it
should be less likely to be misunderstood.
Random Weather Data Additions:
FURTHER I recorded an average Minimum Grass
Temperature of -0.98°C with 23 days being recorded below 0°C. I recorded a
Minimum Grass Temperature of -6.4°C on the 12th, -5.2°C on the 3rd & 19th
& -4.7°C on the 13th.
The Lowest Minimum Temperature of
0.3°C was recorded on a morning where it was reported to be windy in many
areas. This resulted in no minimum temperatures (that I’ve heard) being
recorded below 5.0°C within at least 50 km. I however recorded virtually no wind
until about 1330 (
