Climate Change Chart of Lome, Togo

Overview of climate changes

Changes in sunshine duration

Averaged across calendar months, mean daily sunshine duration showed a difference of -0.39 hours/day compared with the earlier reference period. This is an unweighted comparison of monthly means, rather than a day-weighted annual average. The largest monthly decrease in mean daily sunshine was in June, with a difference of -1.05 hours/day; the largest increase was in August, at a difference of +0.14 hours/day. These month-specific differences show that the comparison varied by calendar month, rather than describing the same change throughout the year.

Changes in rainfall

Averaged across calendar months, mean daily rainfall had a difference of -0.15 mm/day in the more recent period. This unweighted mean of monthly means describes an overall comparison, not a day-weighted annual average or a monthly rainfall total. The clearest monthly contrast was between April, where mean daily rainfall had a difference of -1.99 mm/day, and September, where it had a difference of +1.62 mm/day. These mark the largest monthly decrease and increase respectively; they do not imply that every day or month followed the same pattern.

Temperature changes

Averaged across calendar months, monthly mean temperature showed a difference of +0.93 °C in the more recent period; this is an unweighted comparison of monthly means, not a day-weighted annual average or a measure of daytime maximum temperatures. The largest monthly increase in mean temperature was in November, at a difference of +1.29 °C compared with the earlier reference period; this identifies the strongest monthly increase, not a uniform change across all months.
