Bank Holiday Monday was declared the warmest day of the year so far - but yesterday the mercury climbed just as high.
There were more than 15 hours of sunshine at Aldergrove and the temperature was 25.1C at Castlederg on Monday.
Similar temperatures were recorded in parts of Northern Ireland yesterday.
The warm sun saw tourists and day-trippers flock in their tens of thousands to bask in the sun at beaches, parks and visitor attractions throughout Northern Ireland.
And after a day in which ice cream vendors did a roaring trade, the evening was fine and warm.
Today is also expected to be a scorcher, although the mercury may not climb quite as high, with a maximum temperature of 22C forecast.
The Met Office said there would be low cloud and patchy mist this morning.
However, any fog would clear to leave a dry day with some long spells of sunshine.
The outlook for Thursday through to Saturday is to be a bit more unsettled with a mix of sunny spells and some slow moving and heavy showers or thunderstorms.
