Time of LH surge varies, but it usually comes with a spike in temperature which is noted in the morning of the day of the surge.
LH surge happens when you ovulate and day of ovulation is determined by your menstrual cycle. Discuss with your OBGyn about your length of menstrual cycles to get help regarding ovulation and LH surge. You can also download an app to track ovulation and that would be helpful.

L H surge normally starts approximately 36 hours before ovulation and stays around 14hours after ovulation. This is the most fertile time for pregnancy.

Good luck,

Variable for each person. 36-hour window for beginning of surge to ovulation.
