It might seem like we're seriously getting into warm winter coat and snuggly scarf weather, but don't start packing away your cute summer clothes juuuust yet.
Why? We're going to have what can only be called a September heatwave later this week. For REAL.
Met Eireann has forecast that top temperatures will reach 19 degrees Celsius tomorrow in Leinster, with "a mix of cloud and bright or sunny spells."
You need to make the most of this Indian summer however, 'cos from Wednesday onwards we're back to scattered showers and blustery winds.
Take the day off and have cans in the park anyone?
