Antigua/Barbuda Weather Summary for April 2004

Monthly Normals | Summary Table | Graphs

Mostly fair conditions and light winds continued form the 11^th as a surface low pressure trough continued to drift South Eastwards. Low level moisture maintained by this system led to a few brief passing showers . Skies remained mostly fair across the islands until the 16^th when patches of low level moisture North Eastwards moved across the islands.  These were due mainly to a mid-to-upper level trough over South America which led to the month's maximum daily rainfall 24.0 millimeters on the 17^th.  Winds during this period were mainly from the East at 10 knots while seas remained mainly slight to moderate with swells up to 1.8 meters or 6 feet and at times marginally safe for small craft operations.

The mid-to-upper level trough over South America continued to affect the weather across the islands from the 20^th as  moisture from the South continued to move North Eastwards across the Caribbean islands. This moisture resulted in a few showers occurring daily until  the 27^th when a high pressure system moved across the islands from the West.  This system led to fairer skies but to quite a few brief scattered showers as surges of moisture move across the islands in a brisk wind flow associated with the high pressure system.  Winds were mainly from the East South East at 14.5 knots resulting in the month's maximum 10-minute wind 22 knots on the 28^th at 15:00 UTC.  Seas became moderate to locally rough, as a result of the high pressure system, with waves 1.8-2.4meters or 6-8feet. A small craft advisory was put in effect for choppy seas and gusty winds.
