These are my Temperature & Rainfall Graphs and Figures for Belmopan, BELIZE 2003 - 2015 part
The early Temperature records are not daily, so not so accurate, but by 2008, they are daily Maximum and Minimum temperatures, show by the thin Red line and thin Blue line.. . . . .It is hard to properly see the general temperatures, so the heavy Brown and dark Blue show the 31 day running Averages. . .. .. . The heavy Green is simply a smoothed Median between the max and min. . . .It can't be an Average, because the max could have been only for a few hours during the day and the min could have been for many hours at night. . ..So it is only a Guide, being a Median.
What is very clear is that each year has been very different.
There really were some very high maximum temperatures in 2003 and 2005 ( not shown here at 106░F ) not seen in recent years.
There have been some long periods of Cold in earlier years, but you can't go by the graph for 2003 - 2008 to see how long any period might have been, only showing the extremes.

One pattern that does show through though is that we have two temperature peaks, one in May and one in August, due to the Sun being overhead twice. ( Two Summers ? ). . . . . . .The March and May highs show through due to often no cloud around. . . .August often masked by Rain clouds.. . ..So Rain Clouds plays a big influence in the Summer maximum Temperatures, mainly from June to October usually, but that is highly variable.
Minimum temperatures are different. .. .With random minimums, due to cold fronts from the North coming down, at random, any time from November to March. . . . .But then, during the wet season, the minimums become very common and stable.
I have only been recording Rainfall since 2011. . . . .But I have shown the official Average monthly rains for Belmopan in the 2010 box, for a useful reference.
The vertical Blue lines are the Actual Rain on each Day, left scale 0 - 150mm/Day.. . . . .The heavy Turquoise line is the 31 day running average, but obviously on a different scale, 0 - 600mm/Month. ... It does naturally match exactly the official Monthly averages. . . . . . But look how erratic it is on the real year recordings.. . . . The ▒15 day running averages are shown in heavy light blue and the ▒6 month running average is shown in a thin light blue line. And yet the Yearly average Rains are still fairly similar.
