After the long wintertime minimum, meteor activity starts growing in April. Most significant shower in this period is medium-rate Lyrids, peaking April 22, 07h UT. An IMO investigation in the period 1988-2000 has shown that Lyrids maximum time was variable from year to year between λsol= 32.0 - 32.47 degs (equivalent to 2024 April 21, 23h 20m UT to April 22, 11h UT). Activity was variable too: the closer the peak to the ideal time (λsol= 32.32 degs), the higher the ZHR (up to about 23 hr-1), while the further the peak happened from ideal time, the lower the ZHRs were, down to 14 hr-1. Even shower's peak length was inconstant, with FWHM ranging between 14.8 to 61.7 hours; however, typically Lyrids have a short, quite sharp maximum, so the best rates are normally achieved for just a few hours or so. The analysis also indicated that occasionally, as the highest rates occurred, the Lyrids produced a brief increase in fainter meteors. The last very high maximum was in 1982, when a short lived ZHR of 90 was recorded. For 2024 there are no predictions for any activity increase from theoretical modelling.

Southern Emisphere observers will pay attention to π-Puppids shower; its ZHR is periodic and reached values up to 40 hr-1 when its parent comet (26P / Grigg-Skjellerup) was at perihelion (as in 1977 and 1982). Little activity has been seen at other times, like in 1983 (ZHR=13 hr-1) perhaps suggesting that material has begun to spread further along the comet's orbit. The comet's perihelia in 2018 and 2013 produced no significant meteor activity, though.

Sporadic Meteors annual minimum is over, and SPO rates have started increasing towards their seasonal maximum in late summer. Moreover, some daytime minor showers are also able to increase overall meteor activity. A modest recurring peak in radio rates typically occurs around April 24, due to combined rates of April Piscids, δ-Piscids and ε-Arietids.

For Radio Observers, the (Theoretical) UT peaks for upcoming showers in April 2024 are as follows:

April Piscids (Daytime shower)
Active: April 20 - April 26
Maximum: April 22 (λsol= 32.6 degs)
ZHR: Low

Active: April 14 - April 30
Maximum: April 22, 07h UT (λsol= 32.32 degs)
ZHR: 18 hr-1

π-Puppids (Southern emisphere shower)
Active: April 15 - April 28
Maximum: April 23 (λsol= 33.5 degs)
ZHR: Variable, but typically Low
