Climate Change Chart of Malabo, Equatorial Guinea

Overview of climate changes

Temperature changes

Averaged across calendar months, monthly mean temperature shows a difference of +0.62 °C in the more recent period. This is an unweighted average of the monthly means, rather than a day-weighted annual average, and it describes the aggregate comparison rather than every month. The largest monthly increase was in July, with a difference of +0.87 °C; this is a monthly mean, not a daytime maximum.

Changes in rainfall

Mean daily rainfall, averaged across calendar months, had a difference of -2.49 mm/day compared with the earlier reference period. This unweighted average of monthly means is not a monthly total and does not imply that every month was drier. The largest monthly decrease was in April, with a difference of -6.13 mm/day, while the largest monthly increase was in August, with a difference of +5.72 mm/day. These contrasting monthly shifts show why the overall mean difference should not be read as a uniform change through the calendar.

Changes in sunshine duration

Mean daily sunshine duration averaged across calendar months had a difference of -1.22 hours/day in the more recent period. This is an unweighted summary of the monthly means, not a day-weighted annual figure, and it does not mean sunshine declined in every month. The largest monthly decrease was in September, with a difference of -1.91 hours/day. Both figures describe mean daily hours, rather than total sunshine accumulated over a month.
