Notes:
1. Mean daily temperature and pressure are averaged from the standard 24 hourly observations and not as the average of the maximum and minimum values.
2. Precipitation day has = or >0.01". Trace amounts (< 0.01") are not included in data.
3. Departures from the normal are based on the 1971 to 2000 normals where available (with the exception of the Sea Surface Temperature, which is based on the 1985 to 2000 normal).
Notes:
1. Mean humidity is averaged from the standard 24 hourly observations.
2. Weather Notes indicate a specific condition was observed at least once that day.
3. Departures from the normal are based on the 1971 to 2000 normals where available (with the exception of the Sea Surface Temperature, which is based on the 1985 to 2000 normal).
Key:
PN = Precipitation, PC = Partly Cloudy, MC = Mostly Cloudy, OV = Overcast, DZ = Drizzle, SH = Showers, BS = Blowing Spray GR = Hail, FC = Funnel Cloud, HZ = Haze, RA = Rain, BR = Mist, TS = Thunder Storm/Shower
