How cold, when, and is it for the Houston area? It may be wise to wait before I start my garden.
Thanks.
It shows a low of 33 here on the 18th. We shall see - that's a long way out from here. A few runs had predicted a hard freeze this current week and that didn't pan-out, so I am optimistic that we may be done with our freezes and spring is finally here.
Everyone has an opinion on this, but here is how I generally define spring:
Spring for your location: date of last freeze; the date the growing season begins. This is the most specific criteria and changes every year depending on your location. Note: this is how spring was defined before there was lunar calendar.
Meteorological spring or spring in general: March, April, & May. This is the meteorological spring and probably the best definition when speaking in general terms (i.e., the US transitions into spring, etc.), or when referring to spring without citing a specific location and year.
Astronomical "Spring" or general public use: Spring begins on ~March 21st, the date of the vernal equinox. I put spring in quotes because I feel this is completely arbitrary and a very poor method to define spring. It has little to do with one's location, climate, or growing season - the whole purpose for "defining" Spring on the first place. I realize this is what spring means to probably 99.9% of the population but, in my opinion, it just doesn't make any sense to use the equinox as the marker for a seasonal change, when:
a) meterologically, most of the US is well into spring as defined by warmer weather, increased insolation, and a pattern change and
b) more specifically, a good chunk of the southern US has recorded its last freeze while up north, many places still have a long way to go.
Just my $.02, but the authors on Wikipedia share many of the same sentiments: http://en.wikipedia.org/wiki/Spring_(season)#Definition
