Weather Eye
with John Maunder

Temperatures have been recorded in the Tauranga area at several sites during the last 101 years, including the current Tauranga Airport site from June 1990.

The average afternoon temperature for February 2021 was 23.9 degrees, 2.6 degrees cooler than the 26.5 degrees Celsius recorded in February 2020, which was the warmest February since records began in 1913. February 2021 was the coolest February in terms of average afternoon temperatures for nine years.

It is very common for areas such as Tauranga to have had different observation sites during the years; and the readings from the earlier sites have been adjusted to the present site using ‘standard climatological procedures'. It's considered the temperature series described here is a fair and true record of what the temperature would have been if the current observation site (Tauranga Airport) had been used throughout the period. It's important to note that in considering ‘climate change', the methodology used in computing an 'official' set of climate observations is very important – as otherwise erroneous conclusions may be drawn.

Traditionally, temperature observations have been recorded with a set of maximum and minimum temperature thermometers. These record the daily maximum temperature (usually recorded in mid-afternoon), and daily minimum temperature (usually recorded just before dawn).

This analysis of February temperatures for Tauranga is for the average daily maximum temperatures.

The graph above shows details of the average daily maximum temperatures (called simply ‘afternoon'), for Tauranga for February from 1913-2021.
