To find the three-day moving average, we need to take the average of the past three days.

Day 1 to 3: (93 + 94 + 93) / 3 = 93.33
Day 2 to 4: (94 + 93 + 95) / 3 = 94
Day 3 to 5: (93 + 95 + 92) / 3 = 93.33
Day 4 to 6: (95 + 92 + 86) / 3 = 91
Day 5 to 7: (92 + 86 + 98) / 3 = 92

Therefore, the best choice for the forecasted humidity today based on the three-day moving average is 92.
