The phrase "average spring temperature" is correct and usable in written English.
It can be used when discussing climate data or weather patterns, specifically referring to the typical temperature during the spring season.
Example: "The average spring temperature in this region has been steadily increasing over the past decade."
Alternatives: "typical spring temperature" or "mean spring temperature".
These were: for birth date, total autumn rainfall (mm) between September and December in the autumn of gestation [ 55]; for birth weight, the average spring temperature (°C) between February and April [ 55]; and for first year survival, total winter rainfall (mm) between November and January of the first winter of life [ 49, 54].
In Thoreau's time, the average spring temperature was 42 degrees and the average date of first flowering of the 32 species in the study was May 15.
The authors found that, for both time periods, the early spider orchid's peak flowering time shifted identically and precisely in response to changes in the average spring temperature: they found that flowering times occurred six days earlier for every degree Celsius increase in average springtime temperatures.
The study found that both the herbarium data-set and the more recent field observations showed that for every 1°C (1.8°F) increase in the average spring temperature, the orchids flowered six days earlier.
Birth weight was also affected by the sex of the calf, the mother's status, the mother's age as a quadratic term, birth date and average spring temperature (table 2).
Previous analysis of this population suggested an interaction between average spring temperature and inbreeding effects on birth weight using a marker-based measures [mean d2 [ 47]] but there was no evidence for this using our pedigree-based measure (F1,1108 = 0.73, p = 0.392).
This time last year was the beginning of a record-busting heat wave that gripped Texas, with several cities experiencing 50-plus consecutive days of 100-degree-plus temperatures and an average 2011 summer temperature of 86.7 degrees.
India does have a much younger population than Europe, with a median age of just 26 years, and its people may be better schooled in ways to cope with heat, given India's higher average summer temperature.
Average summer temperature is 30°C from June to September, and average winter temperature is 15°C from November to March.
