Climate Change Chart of Huế, Viet Nam

Overview of climate changes

Temperature changes

Averaged across calendar months, monthly mean temperature shows a difference of +0.73 °C compared with the earlier reference period; 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, with a difference of +1.55 °C. This identifies the strongest increase among the supplied monthly temperature differences, rather than describing every month's change.

Changes in rainfall

Averaged across calendar months, mean daily rainfall has a difference of +0.23 mm/day in the more recent period; this unweighted summary of monthly means is not a day-weighted annual average, and the figures describe daily amounts rather than monthly totals. The largest monthly increase in mean daily rainfall occurred in December, with a difference of +1.65 mm/day. By contrast, the largest monthly decrease was in August, with a difference of -1.38 mm/day; these extremes show that the monthly differences did not all move in the same direction.

Changes in sunshine duration

Averaged across calendar months, mean daily sunshine duration shows a difference of -0.69 hours/day compared with the earlier reference period. This is an unweighted summary of monthly means, not a day-weighted annual average. The largest monthly decrease in mean daily sunshine duration was in December, with a difference of -2.05 hours/day. That monthly extreme is distinct from the across-month average and does not establish that sunshine decreased by the same amount in every month.
