Climate Change Chart of Boracay, Philippines

Overview of climate changes

Temperature changes

The mean difference across calendar months was an increase of +0.80 °C in monthly mean temperature; 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 was in May, at a difference of +1.14 °C. That identifies the strongest increase among the supplied monthly differences, rather than describing every month or a continuous change between periods.

Changes in rainfall

Averaged across calendar months, mean daily rainfall had a difference of +0.58 mm/day; this unweighted mean of monthly means is not a monthly rainfall total or a day-weighted annual average. The largest monthly increase was in July, with a difference of +2.42 mm/day in mean daily rainfall, while November had the largest decrease, at a difference of -0.58 mm/day. These monthly contrasts show that the overall mean difference does not describe each month’s rainfall pattern.

Changes in sunshine duration

Mean daily sunshine duration decreased by -0.48 hours/day when averaged across calendar months; the figure summarizes an unweighted comparison of monthly means, not conditions on every day. The largest monthly decrease occurred in July, with a difference of -1.51 hours/day hours per day. By contrast, March recorded the largest monthly increase, a difference of +0.09 hours/day hours per day. These monthly differences describe contrasts between the reference periods, not a continuous trend.
