The continual record heat took a break during April of 2021. The mean temperature was 1.3 degrees below average and several record cold temperatures were set. On April 2, we didn’t get out of the 50s, which caused us to set a record low-high temperature of 56 degrees. This was followed by the seventh coldest temperature of all-time for month of 36 degrees. Cold fronts were true to their name and continuously made it through the First Coast with reinforcing shots of cold air. The month did not see any days reach the 90 degree mark. We usually average at least one 90 degree day.
The other big during the month was the amount of rainfall we saw. Several weekends were washouts as 5.49 inches of rain fell, during what is usually a drier month for Jacksonville. The rainfall kept the wildfire danger below average and helped the yearly surplus continue. Six days saw at least a half-an-inch of rain or more fall from the sky. A couple of the rounds of rains did bring a threat of severe weather; however the storms did not produce widespread damage. It is yet to be seen if the April showers will bring May flowers. Another benefit of all the rain is the pollen. Pollen levels have quickly tapered off from their extreme levels.
The thunderstorms produced strong winds, in fact, the second highest wind gust of all-time during the month of April was reported on April 10th. Winds gusted to 60 mph during a thunderstorm. We saw zero dense fog days during April, normally we usually see 2 days.
