Expect proper heat, including after dark

Guanacaste suits travellers who enjoy hot weather, but February is less comfortable if you prefer being active throughout the day. Temperatures reach 30°C on 78% of days, so treat the heat as the norm rather than an occasional bonus. Against London's February daytime average of 8°C, the adjustment is considerable. Light, loose clothing makes sense, with a hat and sun protection for time outdoors. Humidity averages 66%, adding to the warm feel, and evenings offer only partial relief rather than a cool reset. Prioritise accommodation where you can sleep comfortably in warm conditions, and keep more demanding plans away from midday.

Dry days and a sea made for swimming

February is among Guanacaste's best months for this combination of heat and dry weather. With about 8.7 hours of sunshine within 11.7 hours of daylight, there is plenty of scope for time outside without packing every activity into the hottest part of the day. Rain is unlikely to dictate your plans, although dry averages are not a guarantee of an entirely rain-free stay. The sea is comfortably warm for swimming, with a year-to-year February range of 26°C to 28°C. That makes the month a strong fit for travellers who want regular swims and relaxed days outdoors. The trade-off is that the water offers a warm dip rather than a sharply cooling break from the heat.
