St. George's, Grenada perches in the southeastern Caribbean. Yet its climate data upends the cliché of endless tropical heat. The headline is rainfall: across all twelve months, St. George's receives only around 3mm of rain, so the island stays essentially dry year-round. There is no wet season to dodge. What shifts the mood month to month is temperature, tracing a neat arc from cool winters through warm summers and back, all under a steady humidity of around 70%. That 70% humidity matters when you pack. It sits at the milder end of tropical readings. Yet it lingers every day. In winter it adds a damp chill. Layers beat one bulky coat. In summer it lends gentle weight to otherwise pleasant warmth. The pairing of near-zero rainfall with moderate humidity is rare, and it makes St. George's good for travelers who crave reliable dry skies without calendar gymnastics. Temperatures in St. George's follow a textbook curve. December through February is the coolest stretch, with daytime highs around 7-9°C (44-48°F) and nights that can dip to 2-3°C (35-38°F). Spring warms gradually, and by June the shift into the warm season is clear. July and August top out at 22°C (72°F), after which a steady cooling carries through to December. For a Caribbean address, winter readings are surprisingly brisk, so arriving in January in shorts and sandals is a rookie error.

Best Time to Visit

Recommended timing for different travel styles.

Beach
July and August deliver the kindest weather in St. George's, with highs of 22°C (72°F) and lows of 14°C (57-58°F) keeping nights agreeable. The 3mm of rain stays steady, so outdoor plans rarely wash out.
Cultural
Culture hounds favor April and May. Temperatures climb into the mid-teens Celsius, crowds thin after the winter rush, and the same dry skies hold.
Adventure
Hikers and trail seekers lean toward May or June. Warming days make exertion pleasant. Yet visitor numbers remain below the summer crest.
Budget
Budget travelers who can shrug off cooler nights will find September and October the quietest months in St. George's, with fewer tourists vying for rooms and tours.

What to Pack

Year-Round Essentials
compact waterproof shell
Even with a 3mm monthly average, brief showers can pop up, and the 70% humidity can feel damp even when skies stay clear.
moisture-wicking base layers
Synthetic fabrics handle the humidity better than cotton, which clings and chafes.
sturdy walking shoes with good grip
important given St. George's hilly terrain.

reusable water bottle
makes sense given the reliably dry conditions.

rounds out the practical kit.

Thermal base layers, a mid-weight fleece or wool layer, a windproof outer jacket
Footwear

Summer (June-August)
Clothing
light daytime clothing
Layering Tip
Even in summer, bring a light layer for evenings when lows dip to 12-14°C (54-57°F).
Autumn (September-November)
Clothing
summer layers still work early in the season, By October the cooler mornings and evenings demand the same mid-weight system that works in spring.
Layering Tip
Early autumn still allows summer layers. Yet by October the cooler mornings and evenings call for the same mid-weight strategy that serves spring travelers well.
Plug Type
Type G
Voltage
230V at 50Hz
Adapter Note
North America runs on 120V at 60Hz. Your gadgets may not. Inspect each power label. Laptops, phone chargers, and camera chargers are usually dual-voltage. Just pack the plug adapter. Hair dryers, curling irons, and single-voltage toys demand a real voltage converter. Bring one. Safe travels.
