  Studies of radio galaxies at TeV energies are fascinating because their jets
are misaligned concerning our sightline. Thus, it provides us with a unique
opportunity to study the structure of their jets, the radiative processes, and
the acceleration mechanisms involved in them. In addition, some radio galaxies
have presented variability in their emission, like the giant radio galaxy M87,
which has reported several activity periods. Due to its duty cycle >95% and
instantaneous field of view of 2 sr, HAWC provides daily monitoring of variable
sources visible from the Northern Hemisphere. In this work, we show the results
of monitoring M87 between January 2015 and December 2018. HAWC's observations
are consistent with the low activity state reported by other instruments (like
H.E.S.S and MAGIC). However, after September 2017 (~MJD 58000), the HAWC
measurements of M87 show hints of higher activity.
