The Southern Delta-Aquarids meteor shower runs from from 12 July to 23rd August, peaking on Thurday July 29 to 30. The number of meteors you will see depends on how high the radiant is above the horizon, and how dark your sky is. This shower is fairly faint, with the highest rate of around a meteor every 7 minutes. This year the shower occurs when the Moon is close to the radiant so lower rates will be seen than usual.
At 11 pm, face east, and look towards Jupiter (the brightest object above the eastern horizon). The radiant is just below Jupiter. This meteor shower should be visible from 10.00 pm until dawn. However, after Moon rise the rates will fall off considerably.
Venus is visible in the late twilight. I have been able to see Venus from 10 minutes after sunset and it is easily seen up to 90 minutes after sunset. Venus has passed Mars and heading towards the bright star Spica
Mars is visible in the evening sky above the north-western horizon in the early evening. Mars is being left behind by Venus but like Venus is heading for Regulus. On the 30th Mars is closest to Regulus.
Jupiter is now above the eastern horizon around 9 pm. Saturn and Jupiter form a line in the sky.
