Months where the sunniest days routinely exceed the typical reading: March, April, May, June, July, August, September, October. Plan sun protection for the worst case, not the average.

People with asthma, heart conditions, or sensitive children may want to avoid these months or limit outdoor activity. Source: CAMS via Open-Meteo.
