======================== Monthly Weather Summary, August 2020
National Meteorological Service of Belize
Climatologically speaking, August is known for its two weeks dry spell known locally as the "maga season". As a result, a marked drop in rainfall can be seen around August when looking at the annual rainfall distribution for the country. Weather systems that typically affect Belize during the month of August are Tropical Waves (TWs), Tropical Upper Tropospheric Troughs (TUTTs) and an occasional Tropical Cyclone (TCs) (tropical depression, tropical storm or hurricane).
The first day of August 2020 started off mostly dry with showers and thunderstorms being generally isolated and confined to the south. Generally fair weather persisted from the 2nd through to the 4th of the month with only isolated showers and thunderstorms over northern and inland areas during the afternoons and over the south at nights. A tropical wave approached the area on the 5th and supported an increase in moisture which resulted in a few showers and thunderstorms over southern areas in the morning then mostly northern and central areas in the afternoon. The activity decreased and then resumed overnight mainly along the coast and over the north.
The tropical wave crossed the country on the 6th morning and maintained relatively moist conditions. This resulted in a few showers and thunderstorms affecting central and northern districts in the morning with the activity increasing over central inland areas during the night. By the 7th the moisture gradually decreased but a few showers and isolated thunderstorms lingered over the area. A gusty easterly airflow prevailed on the 8th and showers and thunderstorms affected central and northern areas in the morning then the activity decreased during the afternoon.
The second tropical wave for August 2020 approached the country on the 9th and moved across the country during the evening of the 10th. The approach of this wave supported an increase in moisture resulting in some showers, thunderstorms and periods of rain mainly over the Belize district and over inland areas in the afternoon then over the Toledo district during the night. Conditions continued cloudy on the 10th but showers and thunderstorms gradually decreased during the day then redeveloped and affected most areas overnight.
Mainly fair weather prevailed over the area from the 11th to the 12th with the exception of the Toledo district at nighttime where a few showers and thunderstorms developed. A weak tropical wave crossed the country on the 13th and supported early morning isolated showers over the Toledo district and along the coast then the activity shifted to the interior by midday.
Relatively dry conditions prevailed from the 14th to the 16th with slightly more activity over southern areas in the nighttime and over inland areas during the afternoon hours. Another weak tropical wave moved across the country early on the 15th.
A relatively moist easterly to northeasterly airflow prevailed on the 17th which supported cloudy conditions along with showers and thunderstorms over central areas after mid-morning then over inland areas in the afternoon. Overnight a further increase in moisture supported the development of some showers and a few thunderstorms across the country that persisted through to the 18th morning with the activity becoming generally isolated during the afternoon. Generally fair conditions dominated most of the country on the 19th except for isolated afternoon thunderstorms that developed over the Orange Walk and Cayo districts.
The 20th morning saw the development of Tropical Depression Fourteen over the west-central Caribbean Sea with maximum sustained winds of 35 miles per hour. A light easterly to southeasterly flow prevailed over the country and weather conditions were mostly fair except for isolated thunderstorms that developed over the mountains in the afternoon and over the Toledo district during the night. Tropical Depression Fourteen was about 240 miles east of Corozal Town on the 21st but mainly fair weather prevailed on the mainland and isolated thunderstorms remained mostly offshore.
Another weak tropical wave crossed the country on the 22nd resulting in isolated thunderstorms and showers over the Belize district in the morning then over northern districts and the mountains in the afternoon as well as over the Toledo district overnight. Slightly moist conditions and an easterly airflow prevailed from the 23rd to the 24th with only isolated thunderstorm and shower activity.
Mainly fair and warm weather prevailed across the country from the 25th to the 26th as a light easterly to southeasterly flow dominated the area. Showers and thunderstorms continued isolated and developed primarily over the mountains during the afternoon time and over the Toledo district at night time. A weak tropical wave passed south of the country on the 25th.
A relatively dry easterly to southeasterly airflow dominated most of the country from the 26th to the end of the month. During this period a tropical wave crossed on the 27th afternoon but this system was weak and produced only isolated showers and thunderstorms over the Corozal and Cayo districts in the afternoon then over the Toledo district overnight. The last tropical wave for the month crossed early on the morning of the 30th but was also very weak and inactive with only isolated showers and thunderstorms confined to the Toledo district.
Several tropical waves crossed the country in August 2020 but they were mostly weak and did not produce significant amounts of rainfall. As a result rainfall was below normal for most of the country except for inland areas. The graph and maps below summarize the total rainfall and average maximum and minimum temperature recorded during the month of August 2020. They also give an indication of how these readings compare to the normal for the month across the stations sampled. As can be seen, rainfall was above normal only in the Cayo district while the remainder of the country received significantly lower than average rainfall. In terms of maximum/daytime temperatures, all of the stations sampled show that daytime temperatures were warmer than normal during August 2020. Nighttime/minimum temperatures were warmer than normal, except for Punta Gorda where nighttime temperatures were slightly cooler than normal.Monthly Rainfall SummaryMonthly Maximum TemperaturesMonthly Minimum TemperaturesRainfall Observed: August 2020 (mm)Rainfall Observed: August 2020 (% Above/Below Average)
