March 2010 was a month of extremes across Puerto Rico and the U.S. Virgin Islands. The month started off with several 90 degree days across the San Juan metropolitan area, followed by record cold temperatures and record precipitation - both associated with a cold front that stalled across the region over the first weekend of the month. However, dry weather quickly returned and temperatures rebounded to levels well above normal by the middle of the month. In fact, by the end of March, the average temperature of 80.7 degrees in San Juan and 80.9 degrees recorded at the airports on both Saint Thomas and Saint Croix, represented temperatures much more characteristic of May than March.

Over the course of the month, a total of 42 climate records were either tied or broken at the official reporting sites in San Juan, Saint Thomas and Saint Croix. The vast majority of these new records were record warm minimum temperatures - likely influenced by the above normal water temperatures that have been recorded across the local Atlantic and Caribbean waters for the past several months. Below is a summary of all the new climate records either tied or broken across the local islands during the month of March and a complete climate report for March 2010 can be found in the Local Data/Records section of our Climate web page under Local Climate Studies
