Their press releases surely won’t admit it, but NOAA’s PREDICTED SUNSPOT NUMBER AND RADIO FLUX dataset appears to show a ‘full-blown’ Grand Solar Minimum running from the 2030s through at least 2040.
NOAA’s Space Weather Prediction Center (SWPC), who’s solar forecasts generally come out higher than NASA’s, are sticking with their originally prediction that it won’t be until mid-2025 before we see the peak of Solar Cycle 25 (SC25) with a sunspot max of 114.6:
NOAA sticks to their guns, predicting that Solar Cycle 25 will max out during the summer of 2025.
The agency then goes on to plot the descent into the minimum of SC25, which they say will run from mid-2025 to 2031 and be comparable to the historically weak cycle just gone, SC24.
Next is where things get interesting.
When sunspots numbers ought be increasing, in line with a ramping-up of Solar Cycle 26, the agency’s data (linked again here) shows that spots do the opposite, they actually continuing dropping
NOAA is forecasting practically ZERO sunspots throughout the 203
There is no ramp-up into Solar Cycle 26
According to NOAA, there won’t be a Solar Cycle 26.
