Climate Change Chart of Nha Trang, Viet Nam

Overview of climate changes

Temperature changes

Averaged across calendar months, monthly mean temperatures show a difference of +0.42 °C between the reference periods; this is an unweighted mean of monthly means, not a day-weighted annual average or a measure of daytime maximum temperatures. The largest monthly increase was in May, at a difference of +0.88 °C. By contrast, July recorded the largest monthly decrease, with a difference of -0.06 °C; these extrema describe individual monthly means, not a uniform change throughout the year.

Changes in rainfall

Mean daily rainfall, averaged across calendar months, had a difference of +1.57 mm/day between the periods. This unweighted mean summarizes the monthly averages; it is not a day-weighted annual figure or a monthly rainfall total. The largest monthly increase occurred in November, with a difference of +5.14 mm/day. This identifies the strongest monthly change in mean daily rainfall, rather than a change in a month’s accumulated total.

Changes in sunshine duration

Averaged across calendar months, mean daily sunshine duration had a difference of -0.47 hours/day. This is an unweighted comparison of monthly means, not a day-weighted annual average. The largest monthly decrease was in July, with a difference of -1.13 hours/day. That monthly result is distinct from the overall mean difference and does not imply the same change in every month.
