Is there a certain time of the year when pool water evaporation is more significant than others? This is my first March with a pool and it seems more noticeable than previous months (last June until now).

To answer the reason for your question, it's probably normal right now. While we can have large daily temperature swings at any point in the year, in the early spring and late fall we consistently get large temperature swings. The bigger the difference between the warmer pool temp and the cooler air temp, the more it evaporates, typically overnight. Wind makes it even worse.
Several years ago we had a big issue with our local lake loosing lots of water. It depends totally on precipitation. Our state University set up monitoring stations for a few years, and found the month for the highest evaporation rate was....November (!) December would have beaten it, but the lake freezes over usually later in that month, putting an end to any substantial evaporation.
Why? Higher average winds, lower to much lower comparative humidity levels. That month accounted for as much water loss as the period between June and September, combined.
But the real reason for the lake water loss - ground water pumping. The deepest area of the lake acted like a bathtub drain into the aquifer, and all the agricultural/industrial/home owner well use exceed that that precipitation replenished. The rains came back, so all is well now. But the lawsuits will go on forever and ever.
