Lying near the [[equator]], Guyana has a [[tropical climate]],<ref>{{cite web |last1=Sánchez-Dávila |first1=Gabriel |title=Clasificación climática de Sudamérica |url=https://storymaps.arcgis.com/stories/b74200791dda49958d6d39eddaca74a0 |website=ArcGIS StoryMaps |access-date=6 November 2024 |language=Spanish |date=15 Sep 2022}}</ref> and temperatures do not vary much throughout the year.<ref name=":0" /> The year has two [[wet season]]s, from December to early February and from late April to mid-August.<ref>Shaw, A.B. (1987), An analysis of the rainfall regimes on the coastal region of Guyana. J. Climatol., 7: 291-302. https://doi.org/10.1002/joc.3370070307 p291</ref>

Although the temperature never gets dangerously high, the combination of heat and humidity can at times seem oppressive.<ref name=":0" /> The entire area is under the influence of the northeast trade winds, and during the midday and afternoon sea breezes bring relief to the coast. Guyana lies south of the path of Caribbean hurricanes and none is known to have hit the country.<ref name=":0" />

Temperatures in [[Georgetown, Guyana|Georgetown]] are quite constant, with an average high of {{convert|32|°C|1}} and an average low of {{convert|24|°C|1}} in the hottest month (July), and an average range of {{convert|29|to|23|°C|°F|1}} in February, the coolest month.<ref name=":0" /> The highest temperature ever recorded in the capital was {{convert|34|°C}} and the lowest  {{convert|20|°C}}.<ref name=":0" /> Humidity averages 70 percent year-round.<ref name=":0" /> Locations in the interior, away from the moderating influence of the ocean, experience slightly wider variations in daily temperature, and nighttime readings as low as {{convert|12|°C|1}} have been recorded.<ref name=":0" /> Humidity in the interior is also slightly lower, averaging around 60 percent.<ref name=":0" />

Rainfall is heaviest in the northwest and lightest in the southeast and interior.<ref name=":0" /> Annual averages on the coast near the Venezuelan border are near {{convert|2500|mm|in|1}}, farther east at [[New Amsterdam, Guyana|New Amsterdam]] {{convert|2000|mm|in|1}}, and {{convert|1500|mm|in|1}} in southern Guyana's [[Rupununi Savannah]].<ref name=":0" /> Areas on the northeast sides of mountains that catch the trade winds average as much as {{convert|3500|mm|in|1}} of precipitation annually.<ref name=":0" /> Although rain falls throughout the year, about 50 percent of the annual total arrives in the summer rainy season that extends from May to the end of July along the coast and from April through September farther inland.<ref name=":0" /> Coastal areas have a second rainy season from November through January.<ref name=":0" /> Rain generally falls in heavy afternoon showers or thunderstorms.<ref name=":0" /> Overcast days are rare; most days include four to eight hours of sunshine from morning through early afternoon.<ref name=":0" />
