Parnaíba, with wind speed values measured at 78 m. As was the

to the seasonal hydro regime is easily identified: Parnaíba
shows the highest wind speed values between September and
December (most of the values higher than 8.5 m/s); even in other
periods, as between April and August, a good wind potential is
available (values higher than 6 m/s). Considering the daily patterns,
the highest values are found between 1 pm and 1 am in all the
observed months.
