In this paper, we present new spectropolarimetric and velocimetric observations of the prototypical classical T Tauri star TW Hya obtained with SPIRou at the Canada-France-Hawaii Telescope, expanding our previous monitoring over two new seasons (2024 and 2025). We confirm that the large-scale magnetic field of TW Hya varied with time and find that it showed fluctuations on a timescale of about a year in addition to the longer term variations outlined in the previous study. Using Zeeman-Doppler imaging, we find that the large-scale field of TW Hya mostly consists of a poloidal dipole of mean polar strength 0.83 kG, inclined at an average 17° to the rotation axis. We also find that the radial velocities of TW Hya, once fully filtered from telluric contamination, were dominated by rotational modulation induced by activity, with residuals of 32 m s ⁻¹ rms. No signal from a putative close-in planet is found, with an upper limit on the planet mass ranging from 0.33 to 0.98 M for distances of 0.053 to 0.41 au from the central star. Emission lines indicate that the mass-accretion rate was equal to 10 ^{−8.33±0.20} M _⊙ yr ⁻¹ on average, with peak-to-peak fluctuations by a factor of ≃5 from season to season. This confirms that accretion onto TW Hya is unstable, with the magnetospheric gap carved by the large-scale field at the center of the disk extending to no further than 33–40% of the corotation radius on average, where the disk’s Keplerian angular velocity equals the rotation rate at the stellar surface.
