What is each month like in Goose Creek?
NOAA's grid estimates the normals every 5 km or so from the stations around each point, terrain included. It smooths between stations, so night lows at the heart of a large city can run warmer than the grid shows: at five big-city airports we compared, the grid's highs were within about 1°F of the station and its lows 1-6°F cooler. The nearest record's high and low are beside each month.

How much snow, how late a frost, what zone and how much sun in Goose Creek?

The USDA's 2023 Plant Hardiness Zone Map puts Goose Creek in zone 8b (ZIP code 29445).
Over a year 81% of the sunlight that would reach the ground under clear skies gets through the clouds in the area (4.8 kWh per square metre a day, NASA POWER 2001-2020); July is the sunniest month (84%) and February the cloudiest (75%).
Charleston's page has its months, frost probabilities, records by month and recent years. NOAA's grid has monthly figures only, so there are no day-by-day month pages for Goose Creek; the nearest record's month pages have them.
