Monthly Weather Summary





Mainly fair and dry weather prevailed during Sunday 1st and Monday 2nd as a light east-southeasterly airflow dominated at the surface and low levels. A broad ridge pattern aloft across northern Central America and the Caribbean supported a convergent / subsident southwesterly flow. Early morning showers affected some coastal areas at first then spread to inland areas during Tuesday 3rd as an inverted trough developed over the western Caribbean over-night and low level winds backed to the east-northeast. Southeasterly surface and low level flow returned to the area during Wednesday 4th as a frontal low deepened over the northwestern Gulf of Mexico. By Thursday 5th, the low ejected northeastwards over the southeastern United States as a ridge of high pressure developed across the Gulf of Mexico and into the northwestern Caribbean Sea. The ridge supported a pre-frontal shear-line moving offshore Yucatan - northern Belize accompanied by showers moving from the northwest to the southeast Rain fall was heaviest over the elevated terrain as the tweenty-four hours rainfall for Baldy Beacon was 35.8mm.

A cold front crossed the country to position over southern coastal waters by mid-day Friday 6th and ushered in cooler and drier air across northern and central areas of the country, while brief showers and periods of light rain continued along southern coastal areas. Weather conditions continued mainly fair, cool and dry during Saturday 7th through Wednesday 11th. High pressure influence dominated and supported a northwesterly flow over the area with only shallow low level moisture along with  a dry / subsident pattern at the upper levels.

Another frontal boundry stalled across the Yucatan Peninsula by Thursday 12th as the associated continental high dominated the Gulf of Mexico. Through Sunday 15th patches of layered low clouds and periods of light rain affected the south of the country as the flow backed to the northeast. During Monday 16th a light east-southeasterly airflow developed and persisted during Tuesday 17th as a retreating surface ridge extended southwestward from the northern Atlantic into the Gulf of Mexico.  

Some early morning fog developed over valleys and low lying areas during Wednesday 18th and a pre-frontal trough pre-ceeded a cold front across Yucatan, Guatemala and Belize with the cold front crossing the country over-night Wednesday 18th into Thursday 19th. The associated high pressure influence supported a gusty northwesterly airflow in the wake of the cold front. Cloudy and cool conditions with periods of light rain prevailed over southern and central areas of the country through Friday 20th with Punta Gorda recording highest rainfall accumulation of 27.6mm.

Mainly fair and dry conditions prevailed during Saturday 21st through Tuesday 24th due to a light northeasterly flow over the area. The flow veered to east-southeasterly during Wednesday 25th. Relatively warm conditions prevailed and except for isolated afternoon thunderstorms over the Cockscomb Range / Basin and light isolated showers over the interior of the Orange Walk and Corozal Districts, little or no rainfall was recorded at most stations. 

By Thursday 26th a pre-frontal trough was analyzed across Yucatan and northern Belize with the cold front trailing across south Florida and into the Bay of Campeche. Shower activity continued generally isolated. Mainly fair weather prevailed during Friday 27th and Saturday 28th with a light easterly flow over the area.
