It's definitely cooler than normal, but as someone like myself who works outside can tell you, April can be the nastiest month. 65 and sunny one day, and 40 and rain the next. I've been working outside for 18 years, I can't remember a single April (though I'm sure theirs at least one) where we didn't get some form of snow. April Imo is the worst month of the year. The weather is bi polar. At least in dec/jan/Feb the weather is consistent
