Kilflynn centre is currently 59m above sea-level, but the village elevation is between 45 and 70m. Its latitude and longitude are 52.3505 and -9.6253 respectively (52° 21' 2" N, 9° 37' 31" W). As with most of the West of Ireland, the weather of the area is strongly affected by the North Atlantic drift and the prevailing south-westerly winds. Being 10 km inland and well beyond the hills to the south-west, Kilflynn is somewhat sheltered from extremes of wind speed and precipitation experienced largely in the south and west of County Kerry. The average yearly rainfall is 1278mm with the wettest months between October and January. The average high/low summer and winter temperatures are 19 °C/12 °C and 9 °C/4 °C respectively. For agriculture and horticulture, the last spring air frost is typically in late March or April, that is to say about five to six weeks later than coastal areas (on exposed land). This is still favourable compared to areas further inland. The agricultural land surrounding the village is regarded as good and mostly unspoilt.
