Not only is the height above ground important so is the shelter the
thermometer is in e.g. protected from dirct sunlight but with free flowing
air around it to get the AIR temp not the SURFACE temp the thermometer is
on. (I think 2 meters is a bit high I think its only 1 but don't take that
as gospel ask a Weather service type what the real deal is.) Also it is
very important to note how the micro climate in your garden differs from
the reports by the weather service. Where I live the temerature can vary
from 32 on the west side of town to 48 out at the east side near the beach
due to the moderating effects of the ocean, not to mention the geography of
your location itself, are you on a hill or down in a low spot? One can
leave you frost free the other a frozen waste! So by all means get the
hi-lo reading thermometer or better yet a digital one with recording
capabilities to our computers and keep a weather log for your garden. (Wind
& Weather in Mendecino, California has some very nice ones along with
shelters etc.)
